The linear function is y = .25x + 1
6(a+3) = 18 + 6a
6(a+3)=6(3+a)
a+3=3+a
a-a=3-3
0a=0
<span>B. all real numbers</span>
As the complete angle is right angle that is 90°
So both the angles should add up to 90°
(3x+2) + (x+16)=90
combine the like terms
4x+18 = 90
Subtract 18 from both sides
4x= 72
divide both sides by 4
x=18
9 ways. I'm not sure how to show work on this
