Answer:
f(-1) = -4
Step-by-step explanation:
f(-1) simply means that what is f(x) when x = -1?
Just plug in -1 for <em>x</em> to find your answer:
f(-1) = -3(-1) + 2(-1) - 5
f(-1) = 3 - 2 - 5
f(-1) = 1 - 5
f(-1) = -4

R = x(A+B)
distribute
R=Ax+Bx
subtract Ax from each side
R-Ax=Bx
divideby x
(R-Ax)/x =B
Choice C
Answer:
m = 9
Step-by-step explanation:
1) Find scale factor
12/8 = 3/2 = 1.5
2) 6x1.5 = 9
OR
1) Set up proportion -> 6/8 = m/12
2) Cross multiply -> 8m = 72
3) Divide both sides by 8
4) m = 9
