Simplify completely x2 + 7x - 30 X + 10 O x² + 4 O x² - 4 Ox-3 Ox+3 x + 3

x - 3

Step-by-step explanation:

sum = 7

Product = -30

Factors = 10 , -3

x² + 7x - 30 = x² + 10x - 3x - 3 *10

                  = x(x + 10) - 3(x + 10)

                  =(x + 10)(x -3)

             = x - 3

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
