-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = -4 + m
or
-7m - 8 = m - 4
or
-8 - 7m = -4 + m
Answer
2) -7m - 8 = m - 4
4) m - 4 = -7m - 8
5) -8 - 7m = -4 + m
Normally you would divide something like this by the cuts made. So if there were cuts of 2 inches on a 10 inch rope, then you should divide 10 by 2. It's the same with this:

Multiply by the reciprocal when you are dividing fractions.
Answer:
{-3, 29, 21, 33}
Step-by-step explanation:
Substitute the x values (domain) to find y, do this for all x's-
f(x) = 6(-2) + 9 = -3
f(x) = 6(0) + 9 = 9
f(x) = 6(2) + 9 = 21
f(x) = 6(4) + 9 = 33
Range-
Take the y values and arrange it from least to greatest <em>(this matters and your teacher may most likely count it wrong if you do not put it in increasing order)</em>
{-3, 29, 21, 33}
