If f(x) = (2x+9)^3, f '(x) = 3(2x+9)^2*(2), or f '(x) = 6(2x+9)^2. Here we used the power rule with chain rule to find the derivative.
Since both the expressions in x are equal to y then they are equal to each other, so
-2x + 3 = 13x - 4
-15x + 3 = -4
-15x = -7
x = 7/15
and y = -2(7/15) + 3 = 31/15 = 2 1/15
It states that a(b + c) = ab + ac
Answer:
I'm not sure but you can try to snap a pic next time for better answer
Step-by-step explanation:
I'm not sure what you mean
The point-slope form:
We have the point (4, -6) and the slope m = 3/5. Substitute:
