Answer:
it's -7 + 5= -2 I think im not sure
So, we first want to think about PEMDAS - parentheses (in this case, brackets first), exponents (that 2³), then multiplication division addition subtraction, from left to right.
First, we take a look at what's inside the bracket:
2³[(15-7)(4-2)] ← Solve the stuff inside the bracket first. Now, we look at parentheses, and solve the things inside the parentheses
2³[(8)(2)] ← Multiply them together since they are inside the bracket
2³[16] ← Now that the bracket is taken care of, we look at the exponent. 2³=8, so:
8*16 ← Now multiply...
The answer is <u>128</u>
The answer is A there you go
X=(7y -1y)

"When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h) Therefore, the slope of the secant line between any two points on this function is 2x + h."
