Answer:

y = 4

Step-by-step explanation:

This looks like a direct variation or constant of proportionality question.

If so, then use the following explanations:

y = kx

-8 = 2k

k = -8 ÷ 2

k = -4

y = -4x

when x = -1

y = -4(-1)

y = 4

If this is the correct answer, then please make this the brainliest answer.

Solve for v in terms of w, x, and y.<br> y=w+v–x

gladu [14]

Answer:

y - w + x

Step-by-step explanation:

y = w + v - x

or y - w + x = w + v - x - w + x [adding x and subtracting w from both sides]

or y - w + x = v

Therefore, v = y - w + x

7/28 in simplest form

vampirchik [111]

$\frac { 7 }{ 28 }$

28 is 4 times 7, so we will rewrite it like that.

$28=4\cdot 7\\ \\ \frac { 7 }{ 28 } =\frac { 7 }{ 4\cdot 7 }$

7 is 7 times 7, so we will rewrite it like that.

$\frac { 7 }{ 28 } =\frac { 7 }{ 4\cdot 7 } =\frac { 1\cdot 7 }{ 4\cdot 7 } =\frac { 1 }{ 4 } \cdot \frac { 7 }{ 7 } =\frac { 1 }{ 4 } \cdot 1=\frac { 1 }{ 4 }$

So the simplest form is,

$\boxed { \frac { 1 }{ 4 } }$
