What is the product of (3x-7)(3x-5)

The answer is 9x² - 36x + 35

FOIL Method or Box Method can be useful in solving this problem.

First Terms Product: 3x × 3x = 9x²

Outside Terms Product: 3x × -5 = -15x

Inner Terms Product: -7 × 3x = -21x

Last Terms Product: -7 × -5 = +35

Combining like terms results in the answer given above.

3x(3x-5)-7(3x-5)

9x^2-15x-21x+35

9x^2-36x+35

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)
