Answer:

$8*12$

Step-by-step explanation:

First, the problem asks for an expression; this means that there should be no equal sign. Also, the keyword "product" means that both the terms must be multiplied. So, $8*12$ is the final expression; this equals 96.

What is the inverse of f(x) = -5x-4

elena55 [62]

Answer:

$\displaystyle f^{-1}(x) = -\frac{1}{5}x - \frac{4}{5}$ .

Step-by-step explanation:

The question has provided an expression for the function $f(x)$ and is asking for its inverse, $f^{-1}(x)$ .

Based on the definition of inverse functions,

$f(f^{-1}(x)) = x$ .

Let $y = f^{-1}(x)$ .

$f(y) = x$ .

$-5 y - 4= x$ .

Solve this equation for $f^{-1}(x) = y$ :

$-5y = x +4$ .

$\displaystyle y = (-\frac{1}{5})\cdot (x + 4) = -\frac{x}{5} -\frac{4}{5}$ .

However, $f^{-1}(x)=y$ As a result,

$\displaystyle f^{-1}(x) = -\frac{x}{5} -\frac{4}{5}$ .

Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)} and G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)}

Snezhnost [94]

Answer:

Step-by-step explanation:

The ordered pair (2, 4) in the relation for function F tells you F(2) = 4.

The ordered pair (2, 5) in the relation for function G tells you G(2) = 5.

Then the sum is ...

(F+G)(2) = F(2) +G(2) = 4 +5

(F+G)(2) = 9
