8 0

Answer:

<em>3000 books</em>

Step-by-step explanation:

The correct function that describes the number of books sold as a function of the number of months her ads have been posted is expressed as;

f(x) = 1000(∛x) + 1000

x is the number of months the ads have been posted

Required:

Number of books sold after 8 months

To get this we will substitute x = 8 into the expression given

f(8) = 1000(∛8) + 1000

f(8) = 1000(2) + 1000

f(8) = 2000 + 1000

f(8) = 3000

<em>Hence the total number of books that were sold after 8 months is 3000 books</em>

8. The sum of two numbers is 8 less than twice the first number. Their difference is 4 less than twice
Delicious77 [7]

Answer:

14 and 6

Step-by-step explanation:

Let's start by naming the first number x.

We can name the second number y.

We can set up equations to model our situation.

x+y=2x-8

x-y=2y-4

Let's simplify the equations.

x+y=2x-8

Subtract 2x from both sides

-x+y=-8

__________

x-y=2y-4

Subtract 2y from both sides.

x-3y=-4

Add the two equations together to eliminate x.

x-3y=-4

-x+y=-8

________

0x-2y=-12

-2y=-12

Divide both sides by -2.

y=6

The second number is 6.

Plug that back in.

x+6=2x-8

Subtract x from both sides

6=x-8

Add 8 to both sides

x=14

The first number is 14

Franklin rolls a pair of six-sided fair dice with sides numbered 1 through 6.
Zarrin [17]

Answer:

The answer is 7/36.

Step-by-step explanation:

First, you find out how many possible outcomes there are from rolling a pair of dice. On one cube, you can roll a 1,2,3,4,5, or 6; so there are 6 outcomes. Since there are two cubes, you multiply 6 by itself to get a total of 36 possible outcomes. Next, you find the probability of the sum of the numbers rolled being an even number; the possibilities are 2,4,6,8,10, or 12, which is 6/36. The probability of rolling a multiple of 5; the one possibility is just 5, since we already accounted for rolling a 10 as an even number. So that is 1/36. The word <u>or</u> says that we add the two probabilities, so the final answer is 6/36+1/36=7/36.
