Question

What is the x-intercept of the equation y = 16 - 0.05x?

a) x = 0
b) x = 16
c) x = 320
d) x = -16

Answer 1

The x-intercept of the equation y = 16 - 0.05x is found by setting y to 0 and solving for x, which yields x = 320.

Step-by-step explanation:

The x-intercept of an equation is the value of x when y is equal to 0. In the equation y = 16 - 0.05x, we can find the x-intercept by setting y to 0 and solving for x:

0 = 16 - 0.05x

Multiplying both sides by -1 to isolate the x term:

-16 = -0.05x

Divide both sides of the equation by -0.05:

x = 320

Therefore, the x-intercept of the equation y = 16 - 0.05x is x = 320.
