Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4(x - 3)
f(9) is x = 9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(9) = 4(9 - 3)
- Subtract: f(9) = 4(6)
- Multiply: f(9) = 24

Answer:
Yes
Step-by-step explanation:
Substituting in x = -7, we get y = 6(-7) = -42, which is the same as the y coordinate of the given point.
1) f(x)=2x+6
f(2)=2(2)+6
=4+6
=10
2)f(x)=3x
f(a+1)=3(a+1)
=3a+3
3)f(x)=3x-1 and g(x)=5x+3
f(2)=3(2)-1
f(2)=6-1
=5
g(3)=5x+3
=5(3)+32
=15+3
=18
f(2)+f(3)=5+18
=23.
Answer: L=45, W=9
Step-by-step explanation:
Perimeter P=108 so if L=5W,
P=2(L+W)=2(5W+W)=2(6W)=12W
108=12W
W=108/12=9
L=5*9=45
