I guess try A I really don’t know
F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8
f^-1(4) = 2(4) - 8
f^-1(4) = 0
Answer:
4th option
Step-by-step explanation:
-2a^2-a
Answer:
108
Step-by-step explanation:
- Base+Base÷2 × height
- 10+7+7=10+14
- 24÷2=12
- 12×9=108
For these problems, there's a rule. For example, in the first problem, the answer is going to be (t+?)(t+?), and the ?s are going to multiply to get the constant and add to get the coefficient in the second term.
