Please help determine the relationship of the following linear equations

For this case we have that the area of the kite is given by the area of two triangles, the triangles share the same base of 3 + 3 = 6 meters and one has height of 2m and the other height of 4m.

So, the total area is given by:

[tex]A = \frac {1} {2} * 6 * 2 + \frac {1} {2} * 6 * 4\\A = \frac {1} {2} 12+ \frac {1} {2} *24\\A = 6 + 12\\A = 18[/tex]

Thus, the area of the kite is [tex]18m ^ 2[/tex]

Answer:

D on edge

Step-by-step explanation:

Step-by-step explanation:

You need to look for where f(x) and g(x) have the same value.  That's at x=0 and x=2.

Answer: If you want to see in what value of x there is true that f(x) = g(x), you need to see in the table when f(x) and g(x) has the same value, this is lock in in table when the second and third values are the same.

This is true for x = 2, where f(2) = 0 and g(0) = 2, and for x = 0, wher f(0) = -3 and g(0) = -3.

Answer :

[tex]\frac{7}{15}[/tex]×[tex]\frac{2}{15}[/tex] = [tex]\frac{14}{225}[/tex]

Step-by-step explanation:

P([tex]Event_{1}[/tex]) = choosing yellow marble from paper bag = [tex]\frac{favourable outcomes}{possible outcomes}[/tex] = [tex]\frac{7}{15}[/tex]

P([tex]Event_{2}[/tex]) = choosing yellow marble from cloth bag = [tex]\frac{favourable outcomes}{possible outcomes}[/tex] = [tex]\frac{2}{15}[/tex]

∵ Resultant outcome is dependent upon both the events and both events are independent from each other, so we can apply intersection rule [ P(A∩B)=P(A)×P(B) ] here

∴ Probability ( Both marbles are yellow) = P([tex]Event_{1}[/tex]) × P([tex]Event_{2}[/tex]) = [tex]\frac{7}{15}[/tex] × [tex]\frac{2}{15}[/tex]

The probability that Tim will draw a yellow marble from both bags is found by multiplying the probability of drawing a yellow marble from each bag, giving a result of 14/225 or approximately 0.0622.

The question is asking to find the probability of Tim drawing two yellow marbles, one from each bag, so this is a question about probability.

We know that there are 7 yellow marbles out of 15 in the paper bag, so the probability of drawing a yellow marble from this bag is 7/15. In the cloth bag, there are 2 yellow marbles out of 15, making the probability of drawing a yellow marble from this bag 2/15.

To find the overall probability that both marbles Tim draws are yellow, we multiply the two independent probabilities: (7/15) × (2/15) = 14/225.

So the probability that Tim will draw a yellow marble from both bags is 14/225, or approximately 0.0622 when expressed as a decimal.

Answer:

Discriminant D = -4 , no real solution

Step-by-step explanation:

Here our equation is

[tex]x^{2}-4x+5=0[/tex]

Discriminant (D)= [tex]b^2-4ac[/tex]

where

a = coefficient of term containing [tex]x^{2}[/tex]

b= coefficient of the term containing [tex]x[/tex]

c is the constant term

hence

a=1 , b =-4 and c=5

Hence

[tex]D=b^2-4ac\\D=(-4)^2-4*1*5\\D=16-20\\D=-4\\[/tex]

Hence D is less than 0 , therefore we do not have any real solution to this quadratic equation.

Answer:

b on edge-The discriminant is −4, so the equation has no real solutions.

Answer:

Perimeter = 20 units

x = 120°

Step-by-step explanation:

We are given a triangle ABC with known side lengths for all three sides and an inscribed circle.

We are to find the perimeter of triangle ABC and the value of x.

Perimeter of triangle ABC = 2 + 2 + 5 + 5 + 3 + 3 = 20 units

The kite shape at the end is a quadrilateral which has a sum of angles of 360 degrees.

Two out of four angles are right angles and one is 60 so we can find the value of x.

x = 360 - (90 + 90 + 60) = 120°

Answer:

6.  20                      8.  120

Step-by-step explanation:

add the side measurements up of the triangle:

2+5+2+3+3+5=7+5+8=20

That shape where the x is a quadrilateral so is't interior angles must add to 360 so you have 90+90+60+x=360

Solving:  230+x=360

So x=360-240=120

Answer:

6π ft

Step-by-step explanation:

I believe you meant CIRCUMFERENCE, the distance around the outer edge of this circle.  The appropriate formula for the circumference is C = 2πr, where r is the radius.  In the illustration we see that line segment PA has length 3 ft.  Thus, the circumference of this circle is C = 2π(3 ft) = 6π ft (the next to last answer choice).

Answer:

=6π ft

Step-by-step explanation:

The circumference of a circle is calculated using the formula C=2πr where r is the radius and C the circumference of the circle.

In the circle provided r= 3ft

C= 2π × (3ft)

=6π ft

We do not use the approximate value of pi as the question demands us to leave pi unsolved.

Answer: se necesitan 4 medidas de B para obtener una de D

Step-by-step explanation:

Las medidas serán entendidas como unidades de.. (A , B o C)

Entonces, de esta manera

1A + 1C = 5B

1A + 1B = 1 C

1B + 1C = 1D

Para lograr el cometido debo combinar las 3 relaciones de cambio de tal manera que se cancelen totalmente las partes A y C utilizando los multiplicadores adecuados

Entonces,

Uso 5 unidades de B para conseguir una de A y una de C

5B = 1A + 1C

Con esa A y otra de B obtengo otra C

1A + 1B = 1C

Por último con esas dos unidades de C y dos unidades mas de B consigo 2 de D

2B+ 2C = 2D

En total utilicé 5 + 1 + 2 = 8 unidades de B para obtener 2 de D

Entonces para obtener una de D necesitaría 4 unidades de B

For a system of linear equations to have a solution, it means that they would cross over at some point, thus if we are looking for a system of linear equations that do not have a solution (ie. they do not cross over), we are looking for two parallel lines.

Now for two lines to be parallel, they must have the same gradient. Thus, we must find the value of a for which both the equations have the same gradient. In order to do this, we should first write both equations in the form y = mx + c, where m is the gradient and c the y-intercept.

1) Equation 1:

(1/2)x - (2/3)y = 7

(3/4)x - y = 21/2 (Multiply both sides by 3/2)

(3/4)x = 21/2 + y (Add y to both sides)

(3/4)x - 21/2 = y (Subtract 21/2 from both sides)

Thus, the first equation may be written as y = (3/4)x - 21/2

2) Equation 2:

ax - 8y = -1

(a/8)x - y = -1/8 (Divide both sides by 8)

(a/8)x = -1/8 + y (Add y to both sides)

(a/8)x + 1/8 = y (Add 1/8 to both sides)

Thus, the second equation may be written as y = (a/8)x + 1/8

Now that we know the equations of the two lines, we can compare their gradients.

Equation 1: m = 3/4

Equation 2: m = a/8

Remember, for the two lines to be parallel, their gradients must be the same. Thus, we must equate the two gradients above to find the value of a:

3/4 = a/8

24/4 = a (Multiply both sides by 8)

6 = a

Therefor, if the system of linear equations has no solution, and a is a constant, the value of a is 6 (answer D).

Answer:

They should expect 30% of 40 out of every 300 of the 12,600, so ...

  0.30 × 40/300 × 12,600 = 504

About 504 residents might be expected to join.

To estimate the number of residents that Muscles can expect to join its new branch, multiply the total number of residents within driving distance by the percentage of respondents who would actually join the gym. Muscles can expect about 1,680 residents to join its new branch.

To estimate the number of residents that Muscles can expect to join its new branch, we can multiply the total number of residents within driving distance by the percentage of respondents who would actually join the gym.

First, we need to calculate the percentage of respondents who would join the gym:

Percentage = (Number of respondents who would join the gym / Total number of respondents) * 100

Percentage = (40 / 300) * 100 = 13.33%

Next, we multiply the estimated percentage by the total number of residents within driving distance:

Number of residents who would join the gym = (Percentage / 100) * Total number of residents within driving distance

Number of residents who would join the gym = (13.33 / 100) * 12,600 = 1,678.5

Therefore, Muscles can expect about 1,680 residents to join its new branch.

The second relation is a degenerate hyperbola. It graphs as the pair of lines y=x and y=-x. It is symmetrical about both the origin and the y-axis. (It also has other lines of symmetry.)

The third relation is a line with slope -1 (represented by dots). It is symmetrical about the origin, but not the y-axis. It is only an odd relation.

Answer:

A. -19

Step-by-step explanation:

There are lots of ways to get there. One of them is to realize that the average rate of change between two adjacent numbers is the negative of their sum. -(9+10) = -19.

Step-by-step explanation:

In order to find the orientation of the parabolas we can follow following steps.

1. if in the equation x is squared , the parabola opens up. Also if its coefficient is negative it opens down.

2. If y is squared , the parabola opens right , and its coefficient is negative , it opens left

but before that we have to convert our function in standard form of the parabola. Our equation is

[tex]y=\sqrt{x-4}[/tex]

hence we square on both sides

[tex]y^2=x-4[/tex]

which is now into one of the standard form of a parabola. here y is squared and its coefficient is not negative hence it opens towards right.
