So we know that:
3(-8 + 4v) = 8v
To find v, first simplify the left hand side:
-24 + 12v = 8v
Then group the "v's" over to the right:
-24 = -4v
-6 = -v
So v = 6

Hope this helped

Which of the following best describes the Constant Question 1 options: The number in a term before the variable. a letter that r

Serjik [45]

Constant is otherwise called term independent. It should not contain any other letters.

So, a constant without a variable best describes a constant.

Can someone help me out with this?

Answer:

-7.5x -12.5, x < -1
7.5x +2.5, x ≥ -1

Step-by-step explanation:

The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:

|x| = -x . . . for x < 0

|x| = x . . . for x ≥ 0

for (x+1) < 0

y = -7.5(x +1) -5 = -7.5x -12.5

for (x+1) ≥ 0

y = 7.5(x +1) -5 = 7.5x +2.5

This means we can write the piecewise function as ...

$y=\begin{cases}-7.5x-12.5,&\text{if }x$
