Train one is going 75 m/s, train two is going 60 m/s, and train three is going 65 m/s.



Explanation:


For number one you could use the slope formula y2-y1/x2-x1, or you could simply just view it from the table that every second that’s passes the distance goes up another 75 meters. This means it would be 75 meters per second.

For the second one it’s a positive correlation that’s related meaning at every whole second (1,2,3...) the line will pass through it, so all you have to do is look at the left and see how much it’s going up by because we know it’s going up by the same amount each time.

Softa [21]

Answer:

Option A, \$607

Step-by-step explanation:

Given: Deborah bought a computer for 25\% off the list price.

The list price is \$2,428.

To find: The amount Deborah spent on the computer.

Solution: We have,

List price of the computer =\$2,428.

Deborah bought the computer for 25\% off the list price.

The amount Deborah spent on the computer =25\% \times 2,428

=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607.

So, Deborah spent \$607 on the computer.

How do you add, subtract, multiply, and divide integers?
aniked [119]
Use a number line to add and subtract. With multiplying and dividing just do it like a whole number. But remember, you take the sign of the larger number (example: -20 + 9 = -29). And when there is two negatives (interger)it equals a positive.I hope this helps!
