Answer:
$4.60
Step-by-step explanation:
(fg)(x) = [f(x)][g(x)]
(fg)(x) = (4x - 5)(3) = 12x - 15
Answer:
15, 6 and - 3
Step-by-step explanation:
Given x - y = 3 , then
(a)
5(x - y) = 5(3) = 15
(b)
2x - 2y ← factor out 2 from each term
= 2(x - y) = 2(3) = 6
(c)
y - x ← factor out - 1 from each term
= - 1(x - y) = - 1(3) = - 3
Step-by-step explanation:
Use properties of similar triangles.

There you are!
