Subtract. Your answer should be a polynomial in standard form.
(3x^3 + 4x²) - (2x^3+ 3x^2– x) =

x³ + x² + x

Step-by-step explanation:

(3x³ + 4x²) - (2x³ + 3x² - x) ← distribute parenthesis

= 3x³ + 4x² - 2x³ - 3x² + x ← collect like terms

= x³ + x² + x

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)
