Y=2/3x+4
I’m pretty sure this is right but tell me if not
Answer:
-2
Step-by-step explanation:
Dividing the given equation by x, we find y to be ...
y = -2/x
Then ...
dy/dx = 2/x^2
and ...
dy/dt = (2/x^2)dx/dt
dx/dt = (x^2/2)dy/dt
When dy/dt = -4 and x=-1, this is ...
dx/dt = (-1)^2/2(-4) = (1/2)(-4)
dx/dt = -2
Answer:
2 (x - 5) (x^2 + 5 x + 25)
Step-by-step explanation:
Factor the following:
2 x^3 - 250
Factor 2 out of 2 x^3 - 250:
2 (x^3 - 125)
x^3 - 125 = x^3 - 5^3:
2 (x^3 - 5^3)
Factor the difference of two cubes. x^3 - 5^3 = (x - 5) (x^2 + x 5 + 5^2):
2 (x - 5) (x^2 + 5 x + 5^2)
5^2 = 25:
Answer: 2 (x - 5) (x^2 + 5 x + 25)
