Which Graph Represents A Line With A Siope Ofand A Y-intercept Equal To That Of The Line Y= 2x-22Answers

Answers

Answer 1

Answer:

last choice

Step-by-step explanation:

So the y-intercept is -2 and the slope is -2/3

The only choices I'm going to look at is first and last because they go through -2 on y-axis.

Now -2/3 is the slope that means the graph should be going down reading it left to right so the last choice,

Answer:

2/3

Step-by-step explanation:

We can find the slope of the line by using points

We have 2 points (-2,0) and (1,2)

Using the formula for slope

m = (y2-y1)/(x2-x1)

   = (2-0)/(1--2)

  = 2/(1+2)

  = 2/3

What is the range of the following data set?

7.7, 8.4, 9, 8, 6.9


0.8


2.1


0.4


1.4

I am pretty sure its 2.1

Answers

The range is given by: largest number in the data set - smallest number in the data set.

In our case, the largest value is 9 and the smallest value is 6.9. Therefor:

Range = 9 - 6.9 = 2.1

Thus, you have correctly identified the answer as the second choice (2.1). It is easy to get confused with much larger data sets but always keep in mind that the range is simply the largest value minus the smallest value. This makes sense since 'range' refers to the spread in something, for example if you were testing your vocal range you would find the highest note you could sing and the lowest note - this is the same here, we are just finding the range of a data set instead.

Answer:

The correct answer is second option

2.1

Step-by-step explanation:

Points to remember

Range of a data set

The range of a data set means that, the difference between the highest and lowest value of the data set.

To find the range of data set

It is given that, a data set

7.7, 8.4, 9, 8, 6.9

Highest value = 9 and lowest value = 6.9

Range = Highest value - lowest value

 = 9 - 6.9 = 2.1

Therefore the correct answer is second option

write the standard equation of a circle with the center at (-1,-4) that passes through the point (-1,-1)​

Answers

Answer:

(x+1)^2+(y+4)^2=9

Step-by-step explanation:

First equation in what I like to call center-radius form is (x-h)^2+(y-k)^2=r^2 where (h,k) is center and r is radius.

So we are given (h,k)=(-1,-4) so we have so far that

(x+1)^2+(y+4)^2=r^2

Passes through the point (-1,-1) means at some point (x,y) takes on the point (-1,-1) so guess what we are going to find r^2 by plugging in that point where x and y are.

(-1+1)^2+(-1+4)^2=r^2

(0)^2+(3)^2=r^2

9=r^2

so the equation of the circle is (x+1)^2+(y+4)^2=9

Answer:

(x + 1)² + (y + 4)² = 9

Step-by-step explanation:

The equation of a circle is:

(x - h)² + (y - k)² = r²

where (h, k) is the center and r is the radius.

The center is (h, k) = (-1, -4).  The radius is the distance from the center to any point on the circle.  (-1, -1) is 3 units above the center, so r = 3.

(x + 1)² + (y + 4)² = 9

What is the range of y =|3x + 1|?


Answers

Answer:

[0,∞), {y|y≥0}

Step-by-step explanation:

The graph of y =|3x + 1| is attached.

By observation, we can see that the the least y-value that the graph can take is y =0 (i.e the x-axis) and the greatest y-value that the graph can take is positive infinity.

Hence the range is [0,∞), {y|y≥0}

Final answer:

The range of the function y = |3x + 1| is [0, infinity), as absolute value functions always yield non-negative values.

Explanation:

The range of the function y = |3x + 1| can be determined by understanding the behavior of absolute value functions. The absolute value function |x| always yields a non-negative value. Therefore, for any real number x, |3x + 1| will also be non-negative. Hence, the range of y = |3x + 1| is [0, ∞), meaning that y can be any real number greater than or equal to zero.

If 2x + y = 6 and m - n = 2, what is the value of (4x + 2y)(4m - 4n)

Answers

Answer:

96

Step-by-step explanation:

If m - n = 2, then 4m - 4n = 4(m - n) = 4(2).

Then (4x + 2y)(4m - 4n) equals (4x + 2y)(8), or 8(4x + 2y).

But we are told that 2x + y = 6.  Multiplying all terms by 2, we get

4x + 2y = 12.  Substituting 12 for 4x + 2y, we get our final answer:

(4x + 2y)(4m - 4n) equals (4x + 2y)(8), or 8(4x + 2y), or 8(12) = 96

Answer:

96

Step-by-step explanation:

(4x + 2y)(4m - 4n) = ?

We have an equation

2x+y =6

Multiply it by 2

2(2x+y) = 2*6

Distribute

4x+2y = 12

Substitute 12 in for 4x+2y into the original problem

12(4m - 4n) = ?

We have an equation

m-n = 2

Multiply this by 4

4(m-n) = 4*2

Distribute

4m-4n = 8

Substitute 8 in for 4m -4n in 12(4m - 4n) = ?

12 * 8 = ?

Answer:  x = 7

`Step-by-step explanation:

Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:

 9 cm       72 cm

----------- = -----------

3x - 20      56 cm

Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²

Dividing both sides by 72 cm, we get:

3x - 20 = (504 cm²) / (72 cm) = 7

Then 3x - 20 = 7, and 3x = 27.  Then x must be 9.

The value of x in the triangle with parallel lines is 9.

To find the value of x in the equation involving a triangle with parallel lines, we can start by simplifying the equation and then solve for x.

The given equation is:

9/72 = (3x - 20)/56

Let's first simplify the left-hand side of the equation:

9/72 = 1/8

Now, the equation becomes:

1/8 = (3x - 20)/56

To isolate x, we can cross-multiply:

1 * 56 = 8 * (3x - 20)

56 = 24x - 160

Next, add 160 to both sides of the equation:

56 + 160 = 24x

216 = 24x

Finally, divide both sides by 24 to solve for x:

x = 216/24

x = 9

So, the value of x in the given equation is 9.

True or false? In a mapping diagram, a relation that is a function can have two arrows coming from the same input value.

Answers

Answer:

Step-by-step explanation:

In a mapping diagram, a relation that is a function can have two arrows coming from the same input value

false

Answer: False.

Step-by-step explanation:

By definition, a relation is a function if each input value has only one output value.

Knowing this, we can say that in a mapping diagram, a function will never have two arrows coming from the same input value.

 In other words, if in a mapping diagram a relation has two arrows coming from the same input value, this means that this input value has two output values, and according to the definition mentioned above, this relation cannot be a function.

Therefore, the statement "In a mapping diagram, a relation that is a function can have two arrows coming from the same input value", is FALSE.

Solve the equation x4 – 26x2 + 25 = 0 in the real number system.

Answers

Answer:

x = -1, 1, -5 , 5.

Step-by-step explanation:

x4 – 26x2 + 25 = 0

Factoring:

(x^2 - 25)(x^2 - 1) = 0

So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.

x^2 - 1  gives  x^2 = 1 and x = +/- 1.

Follow below steps:

To solve the equation x4 − 26x2 + 25 = 0, we can use substitution to simplify the equation. Let's set u = x2, which turns our equation into a quadratic form: u2 − 26u + 25 = 0.

Now, we apply the quadratic formula where a = 1, b = -26, and c = 25 to find the values of u. The quadratic formula is u = (-b ± √(b2 - 4ac))/(2a). Substituting the values, we get the roots for u which are u = 25 and u = 1.

Now we substitute back for x by setting x2 = u, which gives us two separate equations to solve: x2 = 25 and x2 = 1. Solving these, we find the solutions for x to be x = 5, x = -5, x = 1, and x = -1.

For the following system, use the second equation to make a substitution for y in the first equation.

2x + y = 5

Answers

Answer:

Slope of JK = -4/5

Step-by-step explanation:

We know that GHJK is a parallelogram. If GHJK is a parallelogram then the sides of parallelogram will be:

GH, HJ, JK, GK

Hence the opposite sides will be:

GH and JK

HJ and GK

We know that opposite sides of parallelogram are parallel to each other and the slopes of parallel lines is equal.

So the slope of GH and JK will be equal.

And slopes of HJ and GK will be equal.

As we are given the slope of GH which is -4/5, the slope of JK will also be -4/5 because both lines are parallel.
