Find all points on the circle x 2 + y 2 = 100 where the slope is 3 4
1 answer:
(x/sqrt(100-x^2)) = 3/4
x^2 / 100 - x^2 = 9/16
16x^2 = 9(100 - x^2)
16x^2 = 900 - 9x^2
25x^2 = 900
5x = (+-) 30
x = 0 +6 , x = 0 - 6 , and you can find the corresponding y coordinate for each.

Answer:
q = 3 + 1/2r
Step-by-step explanation:
10q - 5r = 30
We want to solve for q
Add 5r to each side
10q - 5r+5r = 30+5r
10q = 30+5r
Divide by 10
10q/10 = 30/10 +5r/10
q = 3 + 1/2r
