Answer: (50,-20)

Step-by-step explanation:

Point B is (100,0).

Point A is (0,-40).

To find C you need the midpoint of both A and B, which means you add both coordinate x and coordinate y together to find the middle of both.

Midpoint of x coordinates:

100+0= 100

100÷2= 50

Midpoint of y coordinates:

0+(-40)= -40

-40÷2= -20

Therefore, point C is (50,-20)

For which survey is a sample not necessary?

BARSIC [14]

Answer:

<h2>How many car accidents involve airbag malfunctions?</h2><h2 />

This is because there's no need to survey an entire population for accurate results.

The other 3, regarding Colorado residents, middle school students, and classmates are considered a population.

For testing the amount of car accidents, a population is not needed.

Jason had three more than four times the amount of money that Jeff has. Together they have $72. How much money does each person

adelina 88 [10]

Answer:

Jason has $58.20 and Jeff has $13.80.

Step-by-step explanation:

Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.

We know that together they have $72. So, we can write the following equation:

$x+y=72$

We know that Jason has three <em>more</em> than four <em>times</em> the amount of money Jeff has. So:

$x=3+4y$

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

$(3+4y)+y=72$

Combine like terms:

$5y+3=72$

Subtract 3 from both sides:

$5y=69$

Divide both sides by 5:

$y=69/5=\$13.80$

So, Jeff has $13.80

We know that Jason has three more than four times the amount of money Jeff has.

Therefore, Jason has:

$x=13.8(4)+3$

Multiply and add:

$x=\$58.20$

So, Jason has $58.20 and Jeff has $13.80.

And we're done!
