Answer:
y' = 9x^2 + 8x^-5
Step-by-step explanation:
General Principle
y' = ax^b
y' = a*b * x^(b-1)
Solution
3x^3 = 3*3x^(3-1)
3x^3 = 9x^2
-2x^-4 = -2*-4 x ^(-4 - 1)
-2x^-4 = 8 x ^-5
Answer
y' = 9x^2 + 8x^-5
8 ÷ (2/3)
Divide 2/3 first, because it's in the parenthesis.
Divide 8 by the product of 2/3 = 12.
Answer:
25^2
5^4
Step-by-step explanation:
625 = 25*25 = 25^2
=5*5 *5*5 = 5^4
100=100%
15=X
15/100 x 100= 15%
Answer:
-7
Step-by-step explanation:
8x - 2 = 7x - 9
8x - 2 - 7x = 7x - 9 - 7x
x - 2 = -9
x - 2 + 2 = -9 + 2
x = -7
