A is the answer since if you graph it, it has those points, or you may just simply plug in the x points that are given and see if they equal the y number
If angles are complementary, they add up to 90 whereas when they are supplementary, the add up to 180. So now let's focus on this problem. It says angle 1 and 2 are complementary. Therefore;
angle 1 + angle 2 =90
x+(3x+30)=90
x+3x+30=90
4x+30=90
-30 -30
4x=60
4/4x=60/4
x=15
Therefore, the value of x is 15
Y = 11.5x + 22
y = -13x + 218
when will their balance be the same.....ur basically just subbing in 1 y for the other and u get :
11.5x + 22 = -13x + 218....now we solve for x
11.5x + 13x = 218 - 22
24.5x = 196
x = 196 / 24.5
x = 8 <== they will be the same at 8 weeks
11.5(8) + 22 = 114
-13(8) + 218 = 114
and they will both have $ 114 at 8 weeks <===
P=S1+S2+S3
P=2.3x+14+2x-0.2x+15
P=4.1x+29
The answer is the first one
Hope this helps
