Math problems suck. can someone me out?

y = 1/3 x +2

Step-by-step explanation:

y = -3x+7

This is in the form y= mx +b so the slope is m which is -3

We want a line the is perpendicular so the new slope is the negative reciprocal

m new = - (-1/3) = 1/3

We have the slope and a point, so we can use point slope form

y-y1 = m(x-x1)

y-1 = 1/3(x--3)

y-1 = 1/3 (x+3)

Distribute the 1/3

y-1 = 1/3 x +1

Add 1 to each side

y-1+1 = 1/3x+1+1

y = 1/3 x +2

This is in slope intercept form

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
