Answer:
Step-by-step explanation:
x^-12/ x^-7
= x^(-12-(-7))
= x^-5
= 1/x^5
13.5 * 12.2 = 164.7 i think that's the answer
D -9 because it has a -3 and its going to be the same - sign
To find the slope take your points, they should be (x1,y1) (x2,y2), proceed to subtract y2-y1 over x2-x1. after you calculate that simplify and put it in y=mx+B (the slope goes in the m position and x is usually left open)
Answer:
