If g(x) = 3x - 5, then g -1(x)= 3x + 5

ludmilkaskok [199]

Hey!

-------------------------------------------------

This just shows to substitute all of x with -1.

g(-1) = 3(-1) - 5

g(-1) = -3 - 5

g(-1) = -8

-------------------------------------------------

Hence, the answer is -8!

Hope This Helped! Good Luck!

F(0) = -5, f(4) = -3

Karolina [17]

Answer:

y = $\frac{1}{2}$ x - 5

Step-by-step explanation:

Given f(0) = - 5 and f(4) = - 3 , then we have the coordinate points

(0, - 5) and (4, - 3)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, - 5) and (x₂, y₂ ) = (4, - 3)

m = $\frac{-3+5}{4-0}$ = $\frac{2}{4}$ = $\frac{1}{2}$

The line crosses the y- axis at (0, - 5) ⇒ c = - 5

y = f(x) = $\frac{1}{2}$ x - 5 ← equation of line

Find QR. A).12 B).-8 C).9 D).6

mihalych1998 [28]

Answer:

D. 6

Step-by-step explanation:

Let's first find x :-

$\sf 3 + 2x + 22 = x + 17$

$\sf 2x + 25 = x + 17$
$\sf 2x - x = 17 - 25$
$\sf x = - 8$

Now that we found x, let's find QR :-

QR = 2x + 22

$\sf QR = 2( - 8) + 22$
$\sf - 16 + 22$
$\sf 6$

Therefore, QR = 6 !!!
