Simplify the expression

2v+8v-5v

5v

Step-by-step explanation:

First you convert all the subtraction to addition: 2v+8v+(-5v)

Then you combine like terms: 2v+3v:

5v

2v + 8v - 5v    combine like terms

= (2 + 8 - 5)v

= (10 - 5)v

= 5v

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)
