Answer:

[-6, 8]

Step-by-step explanation:

Domain: set of all possible input values (x-values)

Range: set of all possible output values (y-values)

The closed circles on the endpoints of the curve mean that those points are included in the interval.

From inspection of the graph, the smallest y-value is -6 and greatest y-value is 8.

To express this in interval notation write the beginning and ending numbers of the interval inside square brackets as the end values are included.

(If the circles were open, and therefore the end values should not be included, use curved brackets).

Therefore the range of the given graph is: [-6, 8]

75% of what equals 30

poizon [28]

Answer:

30 is 75% of 40

Step-by-step explanation:

We have, 75% × x = 30 or, 75/100 x = 30. Multiplying both sides by 100 and dividing both sides by 75, x = 40.

And if you are using a calculator, simply enter 30×100÷75, which will give you the answer.

A company pays 12% commission on sales less than $7,000.00. 14% commission on sales

aleksandrvk [35]

Answer:

The total commission is: $840 + $1,120 + $672 = $2,632

Step-by-step explanation:

Multi-Level Commissions

For sales less than $7,000, a company pays a 12% commission.

For sales between $7,000 and $15,000, the company pays 14%.

For sales greater than $15,000, the company pays 15%.

Let's calculate the commission on sales of $19,480.

For the first $7,000, the commission is:

12*7,000/100 = $840

The remaining sales base is now $19,480-$7,000 = $12,480

For the portion of $8,000 between $7,000 and $15,000, the commission is:

14*$8,000/100 = $1,120

The remaining sales base is now $12,480 - $8,000= $4,480

This portion gets the final 15%:

15*$4,480/100 = $672

The total commission is: $840 + $1,120 + $672 = $2,632

A theme park had 1099 visitors in 3 days.There were twice as many visitors on saturday than on Friday.There were 234 more visito

Blababa [14]

Answer: there were 692 visitors on Saturday.

Step-by-step explanation:

Let x represent the number of visitors that were there on Friday.

Let y represent the number of visitors that were there on Saturday.

Let z represent the number of visitors that were there on Sunday.

The theme park had 1099 visitors in 3 days. It means that

x + y + z = 1099- - - - - - - - - - - - - -1

There were twice as many visitors on saturday than on Friday. This means that

y = 2x

x = y/2

There were 234 more visitors on Sunday than on Saturday. This means that

z = y + 234

Substituting x = y/2 and z = y + 234 into equation 1, it becomes

y/2 + y + y + 234 = 1099

Cross multiplying by 2, it becomes

y + 2y + 2y + 468 = 2198

5y = 2198 - 468

5y = 1730

x = 1730/5

x = 346

y = 2x = 2 × 346

y = 692

z = y + 234 = 692 + 234

z = 926

Which of the following is the solution set to the inequality −25x+14>20? Select one: A. x < -64 B. x > -64 C. x < -1

Sindrei [870]

Answer:

x< -0.24

Step-by-step explanation:

So this is going to sound stupid, but I got x< -0.24 which is just not an option, but this is how I got it...

-25x+14>20

subtract 14 from each side

-25x>6

divide each side by -25

x< -0.24

I switch the way the sign was facing bc I divided by a negative.

Now I know that this must be wrong, but it makes the most sense because I am pretty sure I did all of the math right. Sorry this probably didnt help , but I did a lot of work to try and get the right answer, so Im not putting that work to waste
