4 (negative one-half x + 7) + 5 x = 15
Ronch [10]

Answer:

Step 3 is incorrect

Step-by-step explanation:

4(-1/2x + 7) + 5x = 15

-2x + 28 + 5x = 15

What is the rate of change between (-8,- 8) and (0,8)
iren [92.7K]

{ \qquad\qquad\huge\underline{{\sf Answer}}}

We need to find thr rate of change (slope) of the line joining these two points ~

\qquad \sf  \dashrightarrow \: m =   \dfrac{rise}{run}

\qquad \sf  \dashrightarrow \: m =  \cfrac{8 - ( - 8)}{0 - ( - 8)}

\qquad \sf  \dashrightarrow \: m =  \cfrac{8  +  8}{0  + 8}

\qquad \sf  \dashrightarrow \: m =  \cfrac{16}{8}

\qquad \sf  \dashrightarrow \: m = 2

Slope of the line (m) joining the two points is 2 ~

6. – 4y + 8x = 32 for y
MatroZZZ [7]

Answer:

The answer is: y=2x−8

Step-by-step explanation:

Step 1: Add -8x to both sides.

8x−4y+−8x=32+−8x

−4y=−8x+32

Step 2: Divide both sides by -4.

−4y−4=−8x+32−4

y=2x−8
