Which polynomials are in standard form?
Choose all answers that apply:
10-n
5n+3n^3-1
n+4n^2 -7n^3
none of the above

none of the above

Step-by-step explanation:

The largest square must be the first in the polynomial. Because 10-n, 5n+3n^3-1, and n+4n^2-7n^3  do not follow that rule, the answer must be none of the above.

c

step-by-step explanation:

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)
