D is the correct answer

Radda [10]2 years ago

4 0

Answer:

Step-by-step explanation:

let y = f(x), that is

y = $\frac{2x-3}{5}$

Rearrange making x the subject

Multiply both sides by 5

5y = 2x - 3 ( add 3 to both sides )

5y + 3 = 2x (divide both sides by 2 ) , then

x = $\frac{5y+3}{2}$

Change y back into term of x, hence

$f^{-1}$ (x) = $\frac{5x+3}{2}$ → D

Eric, Cam, and Brooke are playing a game of mini golf on a computer. The computer program for the game stores

andrew-mc [135]

Answer:

Eric

Step-by-step explanation:

First, we determine the distance of each player to the hole using the distance formula.

Given points $(x_1,y_1)$ and (x_2,y_2)$

Distance $=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Eric

The hole is at (3,2)

Eric's golf ball is at point (-6,6)

Distance= $\sqrt{(-6-3)^2+(6-2)^2}$

$=\sqrt{(-9)^2+(4)^2}\\=\sqrt{97} \\\approx 9.85$

Cam

The hole is at (3,2)

Cam's golf ball is at point (8,-6)

Distance= $\sqrt{(8-3)^2+(-6-2)^2}$

$=\sqrt{(5)^2+(-8)^2}\\=\sqrt{89} \approx9.43$

Brooke

The hole is at (3,2)

Brooke's golf ball is at point (10,8)

$Distance=\sqrt{(10-3)^2+(8-2)^2}\\=\sqrt{(7)^2+(6)^2}\\=\sqrt{85} \approx 9.22$

Since Eric's ball is the farthest from the hole, Eric should shoot next.
