The second one because the answer to the first one is a two digit number and the answer to the second is a one digit number, so #2 only uses two 2-digit numbers
F(x) = (-1/2) * (x-3)
y = (-1/2) * (x-3)
⇒ -2y = x - 3
⇒ -2y + 3 = x
⇒ x = -2y + 3
Thus f^-1(x) = -2x + 3
Answer:
n = -14
Step-by-step explanation:
n/2 = -7
Multiply by 2 on both sides to isolate n
n = -7 x 2
n = -14
Comparing forms, you see that
4 = ∛c
The value of c is found by cubing both sides of this equation.
4³ = c = 64
