k(x,9) = (-10,-6)
k*x = -10
k*9 = -6 Distributive property of multiplication
k*9 = -6
k = -6/9
k = -2/3 Get the value of k to solve for the value of x.
k*x = -10
-2/3 * x = -10
x = -10 ÷ -2/3
x = -10 * -3/2
x = (-10 * -3)/2
x = 30/2
x = 15 Choice D.
Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.
The answer is -2 4/5. This is in simplest form because my calculator does everything into simplest form.
Answer:
Both triangles are right triangles because the angle d is 90 degrees in both sides
3 ^ 2 - 2.25^2 = 1.98
4^2 - 1.98^2 = 3.48
x = 3.48
I think it's the last one Which is 160° :)
