(3) y= 5x+ 13

you have to do the rise (ryse - with a y because it is the y value) over the run to get your slope and then subtract your slope from 18 to get 13.

Use the factoring to find the solution to the following equation
NikAS [45]

Hello from MrBillDoesMath!

Answer:  Choice C, -(3 +2/3)

Discussion:

Start with

13x^2 + 56x + 75 =  4x^2 -10x - 46

Subtract 4x^2 from both sides:

(13x^2 - 4x^2) + 56x + 75 = -10x - 46

Add 10x to both sides

(13x^2 - 4x^2) + (56x + 10x) + 75 =  (-10x + 10x) - 46 or

9x^2 + 66x + 75 = -46.

Add 46 to each side

9x^2 +66x + (75 + 46) = 0 =>

9x^2 + 66x + 121 = 0.

This factors as follows:

9x^2 + 66x + 121 =  (3x + 11)^2 = 0 =>

3x + 11 = 0 =>

x = -11/3  = - (3 + (2/3))     which is choice C


Thank you,

MrB
