What is the answer for -3 -4m = -7(-4m+4)-7m

1. Expand

- 3 - 4m = 28m - 28 - 7m

2. Simplify 28m - 28 - 7m to 21m - 28

- 3 - 4m = 21m - 28

3. Add 4m to both sides

- 3 = 21m - 28 + 4m

4. Simplify 21m - 28 + 4m to 25m - 28

-3 = 25m - 28

5. Add 28 to both sides

- 3 + 28 = 25m

6. Simplify - 3 + 28 to 25

25 = 25m

7. Divide both sides by 25

1 = m

8. Switch sides

m = 1

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

55/i dont know i do it for the points
