Answer:

The solution would be (6, -11)

Step-by-step explanation:

In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.

x = -2y - 16

x = -2(-3x + 7) - 16

x = 6x - 14 - 16

x = 6x - 30

-5x = -30

x = 6

Now that we have the value of x, we can find the value of y.

y = -3x + 7

y = -3(6) + 7

y = -18 + 7

y = -11

Let f(x) = x2 − 81. Find f−1(x)

valkas [14]

This equation states that x equals -1. So you plug in -1 to all the x's and solve.
So, your equation would be f(-1) = (-1)(2) - 81
So, f(-1) = -2 - 81
Then, this means that f(-1) = -83
So........
f(-1) is equal to -83
