Find the x intercept of the graph of -5x + 10y = 20

a. -2
b. 2
c. 4
d. -4

D. -4

Step-by-step explanation:

-5x+10y = 20

To find the x intercept set y = 0 and solve for x

-5x+0=20

-5x = 20

Divide by -5

-5x/-5 = 20/-5

x = -4

To answer the question, the first thing we must do is rewrite the following expression:

4 times as many as 25

We rewrite this expression in algebraic form.

We have then:

4 times as many as 25 = 4 * 25

Making the corresponding calculation, we will obtain:

100 is 4 times as many as 25
