First answer is 19600, 17200, 14800, 12400
21/150=.14 or 14%. This is a good answer.
Your points are (1.5,0) and (0,3.5)
The equation for slope-intercept is y2-y1 over x2-x1
3.5-0 over 0-1.5
3.5 over -1.5
Complementary angles are two angles that add up to 90 degrees
So, 2x + 3x = 90 we have to solve for x
5x = 90
Divide each side by 5
x = 18
Plug 18 into x for 3x and 2x
3x = 3(18) = 54
2x= 2(18) = 36
Its 5 because if u do 3x 5 it equals 15 then subtract 2 it gives u 13
