Question

Given the function r(x)=-2/3x+4, find each value. Question 1: r(-6)= Question 2: r(1/2)= Question 3: For what value of x is r(x)=-4? Pls make it simple

Answer 1

1: 8

2: 11/3

3: 12

Explanation:

Basically in the first two parts you need to replace the X from the given equation by the given number, and in the third part replace r(x) by the given value.

1: (-2/3) × (-6) + 4 = 8

2: (-2/3) × (1/2) + 4 = 11/3

3: -4 = (-2/3) × x + 4 Subtract four from both sides

-8 = (-2/3) × x Divide each side by (-2/3)

x = 12
