Classrooms on one side of the language arts building are all numbered with consecutive even integers. If the room with the smallest classroom number, on this side of the building is numbered y, write an expression in y for the sum of the first five classroom numbers in a row

10 you would take 50/ .2

step-by-step explanation:

3.how is solving radical equations different than solving linear equations?

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)
