Answer:
ƒ(a + h) = 2(a^3 + 3a^2h + 3ah^2 + h^3)
Step-by-step explanation:
Put (a+h) in place of x and "simplify" the expression.
f(x) = 2x^3
f(a +h) = 2(a +h)^3 = 2(a^3 +3a^2h +3ah^2 +h^3) . . . . matches 1st choice

It helps to know the expansion of a binomial:
(a +b)^3 = a^3 +3a^2b +3ab^2 +b^3
Even if you don't, you can multiply it out.
(a +b)^3 = (a +b)(a^2 +2ab +b^2) = a^3 +2a^2b +ab^2 +a^2b +2ab^2 +b^3
= a^3 +3a^2b +3ab^2 +b^3
It is 50% because it is half of the total
257,650 rounded to the nearest hundred is 257,700 because it is right at the border (50) we have to round up.
Answer: A module learning
Step-by-step explanation:
The equation of a line in the slope intercept form is expressed as
y = mx + c
where
m represents slope
c represents y intercept
The given equation is
12x + 2y = 6
we would make this equation to look like the slope intercept equation.
12x + 2y = 6
If we subtract 12x from both sides of the equation, it becomes
12x - 12x + 2y = 6 - 12x
2y = 6 - 12x
2y = - 12x + 6
Dividing both sides of the equation by 2, it becomes
y = - 6x + 3
Thus, by comparing with the slope intercept equation,
slope = - 6
y intercept = 3
