Answer:

v = -8

Step-by-step explanation:

First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get 448=-5v-40-56v. After this, we would have to simplify like terms by subtracting 56v from -5v to get 448=-61v-40. We now have to get the variable on one side and to do that, we can add 40 to both sides to get 488=-61v. Finally to get the variable alone, we would have to divide both sides by -61 to get v=-8.

If the area of a circle is 16pi what is the circumference of the circle, circle b, if its radius is 1/2 that of the circle a
Natasha2012 [34]
First find the radius of circle A. You know that the equation is r^2*pi, so just divide both by pi.
r^2*pi=16pi
/pi          /pi
r^2=16
R is 4. That means that circle B is 2, since its radius is half that of circle A.
C=pi2r
C=pi2(2)
C=pi4
C=4pi
The answer is 4pi.

In the xy-plane, the line with equation
Nonamiya [84]
<h3>Answer:  E.  7</h3>

=======================================================

Explanation:

Any point on the x axis always has its y coordinate equal to 0.

Plug in y = 0 and solve for x

y = 4x-28

0 = 4x-28

4x-28 = 0

4x = 28

x = 28/4

x = 7

Therefore, the point (7, 0) is on the line y = 4x-28 and also on the x axis. This is known as an x intercept.

Comparing (7, 0) this to (a, b) shows that a = 7 and b = 0.
