B is a point between A and C, where AC = 5x, AB = 12, and BC = 3x +2. What is the measure of the length of AC¯¯¯¯¯¯¯¯?

A/Q

AC=BC+AB

Put the given values to find value of x

→5x=12+3x+2

→5x-3x=14

→2x=14

→x=14/2

→x=7✓

As given AC=5x

.°. AC=5×7

AC=35✓

correct answer is b. 27/8

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
