Answer: The operation preformed is multiplication.

Step-by-step explanation: When you have a integer that is raised to a power, you must evaluate that integer first. For example, if you are asked to solve 2^3 + 4^7, you must first multiply. 2^3= 8 and 4^7= 16,384 then we must add these two products together to get 16,392.

How to find the product of to the power number: 8^3. We take eight and times it by it's self 3 times to get 512.

Hope this helps!

F(x)=-2x-1 and g(x)=x^2-1. Find (fog)(-5).

serg [7]

Answer: - 49

Step-by-step explanation:

f(x) = -2x - 1

g(x) = $x^{2}$ - 1

fg(x) = f ( $x^{2}$ - 1) , we just put in the value of g(x) , the next thing is to substitute $x^{2}$ - 1 for the value of x in f(x) , that is

fg(x) = -2( $x^{2}$ - 1) - 1

fg(x) = -2 $x^{2}$ + 2 - 1

fg(x) = -2 $x^{2}$ + 1

Therefore : fg(-5) means we will substitute -5 for x in fg(x) , that is

fg(-5) = -2 ( $(-5)^{2}$ + 1

fg(-5) = -2(25) + 1

fg(-5) = -50 + 1

fg(-5) = -49

D. 9x-X+5x =260 Bx= 200

yan [13]

Answer:

We first must solve for x

$9x-x+5x=260\\13x=260\\x=30$

When we have x, we put it in to the second equation

$Bx=200\\\\B=\frac{200}{x} \\\\B=\frac{200}{30}\\\\B=\frac{20}{3}$

A high school is conducting a vote to see which class (freshman, sophomore, junior, or senior) can go to see a play performance.

Lady_Fox [76]

The probability of an event is considered fair when the probability of the event happening is equally likely.

Thus, the way each vote should be counted so that the outcome is fair is "The freshman votes count as 1 vote, the sophomore as 1.14 votes, the juniors as 1.45 votes, and the seniors as 1.23 votes."
