Answer:
15
Step-by-step explanation:
if you put x=-15
f(x) = 5*-5 +40
=-25+40
=15
Answer:
It's division because to get x by itself, you need to divide both sides. X = 9
Step-by-step explanation:
6x = 54
Divide both sides by 6
54/6 = 9
Answer:
-5/7
Step-by-step explanation:
remember slope is eqaul to rise over run.
6-11 = -5 so it rose down by 5 units
10 - 3 = 7 so it ran 7 units
thus
slope= -5/7
