xy = is a constant (k) so k = -360. When y = - 36, x = 10

find x+x+x when x=15 15+15+15=45
The x-intercept is (15 0)
you wanna find out 15n=1275 you have to find out what times what equals 1275 alright =) by a fifth grader Majd Merai =) i rock hehehe

y = 8
y = 3x y = 3*19 = 57
The phrase "varies directly as" means that there is a number k such that w = k(2x - 1). From the results given for w = 9 when x = 2, 9 = k(4 - 1), or k = 3. Then when w is 15, 15 = 3(2x - 1), or 15 = 6x - 3, or 6x = 15 + 3, or x = 18/6 = 3.
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
If P varies jointly as q, r and s - assume this is in direct proportion, then P ∝ qrs so P = kqrs where k is a constant.70 = k x 7 x 5 x 4 = 140k : k = 140/70 = 0.5When q = 2, r = 15 and s = 7 then,P = 0.5 x 2 x 15 x 7 = 105

k = 2 Explanation: when z varies directly proportional to x means a division c = z x where c is a constant of proportionality when z varies inversely proportional to x it means a product z y = c now with both k = z y x z = 8 ; x = 12 and y = 3 k = 8.3 12 k = 2
The question is incomplete and unanswerable as written
First, find 15% of 2037.00, by doing (2037*0.15), which equals 305.55; then subtract this 15% amount from 2037, so (2037-305.55) which equals 1731.45.
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
