Answer:

Step-by-step explanation:
we know that
The "power rule" tells us that to raise a power to a power, just multiply the exponents
so

we have

Applying the "power rule"

Answer:
9
Step-by-step explanation:
x-5+7=11
First think of what +7 = 11 then subtract by 5
check :)
You can solve this in two ways.
1. Graphical. Plot the graph for x between -5 and 1 (see attachement).
The vertex of the graph is the peak of the curve, which has the coordinates x=-2, y=-9.
2. Analytical. Calculate the derivative of the function f(x)

Solve the equation:

will give the solution x=-2.
Replace x=-2 in the f(x) function and you'll get the value of y:

You get the same answer: x=-2, y=-9
So the answer is
<span>B. (-2, -9)</span>
In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.
12x + 4
divide 4 from each monomial
12x/4 = 3x
4/4 = 1
4(3x + 1) is a equivalent expression.
hope this helps
