Which of these are the intercepts of the graph of y = 3x – 12?

x-intercept: 4

y-intercept: -12

Step-by-step explanation:

Well our formula is y=mx+b where m is the slope and b is the y-intercept. -12 takes the place of the b, so -12 is the y-intercept.

To find the x-intercept, we need to make y=0.

0=3x-12

Add 12 to both sides

12=3x

Divide both sides by 3

x=4

The x-intercept is 4 and the y-intercept is -12.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
