What is the solution set of x2 – 10 = 30x? {–220, 250} {–250, 220} {15 – , 15 + } {–15 – , –15 + }

x^2 - 10 = 30x

x^2 = 30x + 10

x^2 - 30x = 10

x^2 - 30x + 225 = 235

(x - 15)^2 = 235

x - 15 = √235

x = 15 ± √235 is the solution set.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
