F(x) = 2x + 1 and g(x) = -5x + 2
f(g(x)) = 2(-5x + 2) + 1 = -10x + 4 + 1 = -10x + 5
f(g(3)) = -10(3) + 5 = -30 + 5 = -25
Answer: where’s the picture?
Step-by-step explanation:
Step-by-step explanation:
y = 4 when x = 8 So, 4 = 8k
k = 1/2
y = (1/2)x
Therefore, when x = 10, y = (1/2)(10) = 5
This should be recognized as the difference of perfect squares which is of the form:
(a^2-b^2) and the difference of squares always factors to:
(a-b)(a+b) in this case:
(3x-8)(3x+8)
