Answer:
Step-by-step explanation:
when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.
You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.
When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.

Answer:
if you are being asked what the values of the x and y variables are, x=5/2 and y=4
Step-by-step explanation:
In order to solve this problem you will want to isolate one of the two variables in both equations.
I isolated the y variable in both equations so you have:
4x+y=14, when you isolate the y variable, you will get: y=-4x+14
6x-3y=3, same procedure isolate y: 6x-3=3y, now simplify so you only have y: 2x-1=y.
Now that you have the two equations which a common variable, solve them by making the two equations equal to each other like so:
-4x+14=2x-1, now you want to have all the x variable terms on one side and all the constants on the other, you will add "4x" to each side of the equal sign and then add "1" to each side to leave you with: 15=6x
now divide both sides by 6 to obtain your x value: x=15/6 simplifies to 5/2
then plug your x-value into one of the two equations we made earlier:
y=2x-1
y=2(5/2)-1
y=5-1
y=4
now you have calculated the values of your x and y values
Hi there! Hopefully this helps!

<h2>Answer: r = 7.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2>
Swap sides so that all variable terms are on the left hand side.
Subtract 10 from both sides.
<h2>Subtract 10 from 17 to get, you guessed it, 7!</h2>
