Answer:
h(-6) = 3(-6)² - 6(-6) + 4
= 3(36) + 36 + 4
= 148
You basically just substitute x with -6 that's all
A.) x (5 + x) = 5x + x^2
B.) 2 (5 + x) = 10 + 2x
Answer:
17
Step-by-step explanation:
Substitute "x" for "5" in the equation
3(5) + 2
15 + 2

Answer: 45.71 - 6x = y
Step-by-step explanation:
45.71 - 6x = y
x= the amount 1 pack of markers cost
y= how much money Heather has after the donation
Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)} and G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)} (F + G) (2) =

Answer:
9
Step-by-step explanation:
(F+G)(2)
=F(2)+G(2)
Stop!
F(2) means what is y when x=2 looking at function F.
F(2)=4 since F has the ordered pair (2,4) which says when x=2, y=4.
G(2) means what is y when x=2 looking at function G.
G(2)=5 since G has the ordered pair (2,5) which says when x=2, y=5.
G(2)=5.
Continue!
(F+G)(2)
=F(2)+G(2)
=4+5
=9
