A company can buy packages of 500 sheets of paper for $4. At that rate, how much paper can be bought for $2000? Group of answer
Alexandra [31]
Your answer is 250,000. There are two ways to do this problem.

1) Solve 500/4 to find out how many sheets of paper you get per every dollar. — Your answer is 125 sheets for $1. Then you multiply that answer by 2000, and get 250,000. Which means you get 250,000 sheets of paper for $2000.

2) You can divide 2000 by 4 & that gets you 500, you can then multiply that by 500 & you will get 250,000.

Hope this helps.

If y = 3x – 4 and the domain is { -3, -1, 4}, find the range. When the domain is -3, the range is ______. Show your work to find
Dafna1 [17]
<h2>Hello!</h2>

The answer is:

When the domain is -3, the range is -13.

<h2>Why?</h2>

To solve the problem, we need to remember that the domain is also known as the input of the function, and the range of the function is also known as the output of the function.

We are given the inputs and we are asked to calculate the output of the function at -3, so, evaluating -3 into the function, we have:

y=3x-4\\f(x)=3x-4\\f(-3)=3*(-3)-4=-9-4=-13\\

Hence, we have that when the domain is -3, the range is -13.

Have a nice day!
