Two parallel lines are crossed by a transversal.What is the value of m?

Answer:

No solution

Step-by-step explanation:

Suppose the number is [tex]y[/tex] so ([tex]y = ...[/tex]).

Now [tex]y[/tex] is equal to twice a smaller number plus 3. Assuming the smaller number as [tex]x[/tex], we can write it as:

[tex]y = 2x + 3[/tex] --- (1)

Also, the same number [tex]y[/tex] is equal to twice the sum of smaller number and 1:

[tex]y=2x+1[/tex] --- (2)

Now for both of these equations, we need to find a point which satisfies them.

For example, for equation 1, take [tex]y=5[/tex] which means [tex]2(1) + 3[/tex] so the solution will be (1, 3).

Substituting the same value of y here in equation 2:

[tex]5=2(2)+1[/tex] so the solution for this will be (2, 5).

It means that there is no such point which can satisfy both the equations. Hence, there is no solution possible for these two equations.

Answer: The system of equations HAS NO SOLUTION.

Step-by-step explanation:

Let be "y" the first number and "x" the smaller number.

Since the first number  is equal to twice a smaller number plus 3, then:

[tex]y=2x+3[/tex]  (Equation 1)

Since the same number is equal to twice the sum of the smaller number and 1, then:

[tex]y=2(x+1)[/tex]

[tex]y=2x+2[/tex]  (Equation 2)

We need to remember that the equation of the line in Slope-Intercept form is:

 [tex]y=mx+b[/tex]  

Where "m" is the slope and "b" is the y-intercept.

You can observe in the Equation 1 that the slope of this line is 2 and you can notice in the Equation 2 that the slope of that line is also 2. Therefore, the lines are parallel and the system of equations has no solution.

the answer is D cuz 45+45=90 and 90+90=180

Answer:

D. [tex]45^{o}[/tex], [tex]45^{o}[/tex], [tex]90^{o}[/tex]

Step-by-step explanation:

Angles of a triangle always add u to [tex]180^{o}[/tex]. If one angle measures [tex]90^{o}[/tex], then the two remaining angles must add up to 180 - 90 = 90.

Since the two angles have equal measures, we can set up an equation:

2a = 90 (where a = angle of one equal measure)

a = 45.

Therefore, the angle measures of the triangle are [tex]45^{o}[/tex], [tex]45^{o}[/tex], [tex]90^{o}[/tex], or answer choice D.

Answer:

C) x = y - 6

Step-by-step explanation:

you have to make it in terms of x, or isolate x:

y = x + 6

- 6 from both sides

y - 6 = x + 6 - 6

combine 6 and -6

y - 6 = x

so, x = y - 6

Answer:

D. 49 sq. units

Step-by-step explanation:

Find the area of the triangle up top first then multiply it by 4 to get the area of the rhombus up top:

4 x 3 = 12  

12/2 = 6

6 x 4 = 24

now solve the lower square:

5 x 5 = 25

now add the two together:

25 + 24 = 49

Answer:

Correct option is:

D. 49 sq. units

Step-by-step explanation:

The irregular polygon shown is the combination of rhombus and square

The lower part of the polygon is square with side 5 units

and the upper part of the polygon with rhombus with diagonal (4+4)=8 and (3+3)=6 units

Area of irregular polygon=Area of square+Area of rhombus

                                         = side²+Product of diagonals/2

                                         = 5²+(8×6)/2  sq. units

                                         = (25+24) sq. units

                                         = 49 sq. units

Hence, Correct option is:

D. 49 sq. units

Answer:

y=-3/2 x +12

Step-by-step explanation:

Solve for y.

2y+3x=24

We want 2y by itself so I will subtract 3x on both sides giving:

2y=-3x+24

Now I will divide both sides by 2 giving:

y=-3/2 x+24/2

Simplifying this gives:

y=-3/2 x+12

The slope is -3/2

The y-intercept is 12

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2y + 3x = 24 into this form

Subtract 3x from both sides

2y = - 3x + 24 ( divide all terms by 2 )

y = - [tex]\frac{3}{2}[/tex] x + 12 ← in slope- intercept form

Answer:

Range of the given function is [ 5 , ∞ )

Step-by-step explanation:

Given function is [tex]y\:=\:\sqrt{x}+5[/tex]

We need to find Range of the given function.

The Range of function is the set of all possible values of the dependent variable ( here, y )  , after substituting the value of domain.

We know that square root can not have negative value. So, Domain of the given function is all non negative real number.

That is Domain = { x : x ∈ R and x ≥ 0 } = [ 0 , ∞ )

Now for range,

put x = 0 in given function,

[tex]y\:=\:\sqrt{0}+5=5[/tex]  

⇒ Minimum value of range is 5

put x = ∞ in given function,

[tex]y\:=\:\sqrt{\infinity}+5=\infinity+5=\infinity[/tex]  

⇒ Maximum value of range is ∞

Thus, Range  = { y : y ∈ R and y ≥ 5 } = [ 5 , ∞ )

Therefore, Range of the given function is [ 5 , ∞ )

Step-by-step explanation:

The value of the discriminant determines the nature of the roots

• If b² - 4ac > 0 then roots are real and distinct

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 then roots are not real

Here b² - 4ac = 4 > 0

Hence roots are real and distinct

Answer:

Part 1)

-31x - 19y=95

-14x + 19 y = 76

The solution is the point (-3.8,1.2)

The system is consistent independent

Part 2)

31x - 19y=95

14x + 19y = 76

The solution is the point (3.8,1.2)

The system is consistent independent

Part 3)

31x + 19y = 95

14x - 19y = 76​

The solution is the point (3.8,-1.2)

The system is consistent independent

Step-by-step explanation:

Part 1) we have

-31x-19y=95 -----> equation A

-14x+19y=76 ---> equation B

Solve the system of equations by elimination

Adds equation A and equation B

-31x-14x=95+76

-45x=171

x=-3.8

Find the value of y

-14(-3.8)+19y=76

19y=76-53.2

y=22.8/19=1.2

The solution is the point (-3.8,1.2)

The system has only one solution

therefore

The system is consistent independent

Part 2) we have

31x-19y=95 -----> equation A

14x+19y=76 ---> equation B

Solve the system of equations by elimination

Adds equation A and equation B

31x+14x=95+76

45x=171

x=3.8

Find the value of y

14(3.8)+19y=76

19y=76-53.2

y=22.8/19=1.2

The solution is the point (3.8,1.2)

The system has only one solution

therefore

The system is consistent independent

Part 3) we have

31x+19y=95 -----> equation A

14x-19y=76 ---> equation B

Solve the system of equations by elimination

Adds equation A and equation B

31x+14x=95+76

45x=171

x=3.8

Find the value of y

14(3.8)-19y=76

-19y=76-53.2

y=-22.8/19=-1.2

The solution is the point (3.8,-1.2)

The system has only one solution

therefore

The system is consistent independent

To determine the type of system, we need to look at the coefficients of the variables and the constants. For the system of linear equations:
```
31x - 19y = 95
-14x + 19y = 76
```
Let's perform the steps to find the solution:
1. We will use elimination or substitution to solve for the variables x and y.
2. We will verify the resulting solution to ensure that it solves both equations.
**Step 1: Elimination**
By adding the two equations together, the y terms will eliminate each other:
```
31x - 19y = 95
-14x + 19y = 76
-----------------
(31x - 14x) + (-19y + 19y) = 95 + 76
17x = 171
```
Divide both sides by 17 to solve for x:
```
x = 171 / 17
x = 10
```
**Step 2: Substitution**
Now that we have x, let's substitute it into one of the original equations to find y. We can use the first equation:
```
31(10) - 19y = 95
310 - 19y = 95
``
Subtract 310 from both sides:
```
-19y = 95 - 310
-19y = -215
```
Divide both sides by -19 to solve for y:
```
y = -215 / -19
y = 11.3158
```
The estimated values of x and y are (10, 11.3158). Since these are not exact values from the multiple choices, it seems there might be a rounding or calculation error. Let's recheck:
```
y = -215 / -19
y = 11.3158...
```
Given the options, the rounded value would be y = 11.3.
**Type of System:**
Given that we were able to find unique values for x and y, the system is "consistent-independent" because it has one solution.
**System with the Same Solution:**
A system with the same solution will have the same coefficients for the variables or will be multiples of one another.
**Estimated Solution:**
As worked out above, x = 10 and y ≈ 11.3. Since this isn't precisely written in the choices, we have to consider rounding for y, which would be approximately 11.3.
With these considerations, the answer to fill the table is:
- Type of System: consistent-independent
- System with the Same Solution: Not provided precisely, but typically it would have proportional coefficients.
- Estimated Solution: (10, 11.3 - considering the second decimal place)
Please note that since we're manually calculating the solution, there may be some approximation in the final values. If exact arithmetic were applied, you should expect to find a precise value for y that matches one of the options more closely.

Answer:

Total Cost = 14.50

Step-by-step explanation:

We have to assume that the third child pays a regular fee to get in.

2 adults = 2 * $4.50 =      $9.00

2 children = 2*$2.75/2=   $2.75

1 more child=1*$2.75   =   $2.75

Total                                   $14.50              

The 2 children 1/2 price is rather tricky. You could firgure out what 1/2 price is and then just double it, but that is rather long. And it will come to what I have. So let's try it

1/2 of 2.75 = 1.375

2 * 1.375 = 2.75

It is just as easy to show it rather than doing it.

Answer:

x = -5/4, y = 0

Step-by-step explanation:

Solve the following system:

{4 x + 6 y = -5 | (equation 1)

{8 x = 12 y - 10 | (equation 2)

Express the system in standard form:

{4 x + 6 y = -5 | (equation 1)

{8 x - 12 y = -10 | (equation 2)

Swap equation 1 with equation 2:

{8 x - 12 y = -10 | (equation 1)

{4 x + 6 y = -5 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{8 x - 12 y = -10 | (equation 1)

{0 x+12 y = 0 | (equation 2)

Divide equation 1 by 2:

{4 x - 6 y = -5 | (equation 1)

{0 x+12 y = 0 | (equation 2)

Divide equation 2 by 12:

{4 x - 6 y = -5 | (equation 1)

{0 x+y = 0 | (equation 2)

Add 6 × (equation 2) to equation 1:

{4 x+0 y = -5 | (equation 1)

{0 x+y = 0 | (equation 2)

Divide equation 1 by 4:

{x+0 y = (-5)/4 | (equation 1)

{0 x+y = 0 | (equation 2)

Collect results:

Answer:  {x = -5/4, y = 0

The system of linear equations provided has an infinite number of solutions. This is concluded after subtracting the second equation from twice the first equation, resulting in 0 = 0, which implies the system's equations are equivalent.

The system given is a system of linear equations. We can solve it using either substitution or elimination method. However, in this case, the elimination method seems easier as you can simply subtract the second equation from twice the first equation.

Answer:

∞ or undefined

Step-by-step explanation:

The slope of a line that passes through two points A(x₁,y₁) and B( x₂,y₂) is found by finding the ratio of the change in y (y₂-y₁) to the change in x (x₂-x₁)

Thus the provided line has a slope of:

(13-⁻8)/(4-4)= 21/0

= ∞

This is a vertically perpendicular line through x=4

To find the two numbers, we can set up a system of equations using the given information. Solving this system of equations, we find that the two numbers are 2 and 2, or -2 and -2.

To solve this problem, we can use the given information to set up a system of equations. Let's assume the two numbers are x and y. From the problem, we know that

[tex]x^2 + y^2[/tex] = 8 and xy = 4.

We can solve this system of equations by substituting the value of y from the second equation into the first equation. This gives us [tex]x^2 + (4/x)^2[/tex] = 8. Multiplying both sides by [tex]x^2[/tex] gives us [tex]x^4 + 16 = 8x^2[/tex]. Rearranging the equation and factoring, we get [tex]x^4 - 8x^2[/tex] + 16 = 0.

This equation can be factored as [tex](x^2 - 4)(x^2 - 4)[/tex] = 0. Taking the square root of both sides, we find that [tex]x^2[/tex] = 4. Solving for x, we get x = ±2. Substituting these values back into the second equation, we find that the two numbers are 2 and 2, or -2 and -2.

Therefore, it's the first choice– [tex]\frac{x-3}{x^{2}-4 }[/tex]

Answer:

[tex]x^2-3/x^2-4[/tex]

Step-by-step explanation:

An excluded value of x for any rational function or expression is when you have any value of x that makes the value of the function undefined. Thus, these values ​​must be excluded from the domain of the function.

in order to know if a value is an excluded value you have to calculate it in the expression:

x=-2

[tex]x^2-3/x^2-4[/tex]=[tex](-2)^2-3/(-2)^2-4[/tex]=[tex]4-3/4-4[/tex]= function undefined (because denominator 0 is undefined)

380 square feet

Step-by-step explanation:

Area of composite solid = Base area + area of side rectangles + area of triangles

To find the area of base

Base area = length * width

 = 240 ft²

To find the area of triangle

Here base of triangle = 10 ft and height = 7 ft

Area  of 4 triangles =4 * area of single triangle = 4 * (bh)/2

 = 4 *(10 * 7)/2 = 140 ft²

Without additional context, the measure of angle 2 cannot be specific. However, the three given angles do not comprise a valid triangle. More information is required.

To find the measure of angle 2, we need to use the properties of angles formed by parallel lines and a transversal. Angle 2 is an alternate interior angle with angle 5, as they are on opposite sides of the transversal line and between the parallel lines. Therefore, angle 2 is also equal to angle 5, which measures 120°. So the measure of angle 2 is 120°.

The question didn't provide enough context or information to specifically determine the measure of angle 2. However, if we look at the three angles provided – 30°, 120°, and 60° – it's plausible that these angles might comprise a triangle since the sum of all angles in a triangle is 180° (30° + 120° + 60° = 210°, so not a valid triangle). We'd need more information to accurately determine the measure of angle 2.
