Answer:
(0,4)
Step-by-step explanation:
Subtract the first equation from the second, obtaining y = 4. Then substitute 4 for y in the first equation, obtaining x + 2(4) = 8; it follows that x = 0.
The solution is (0,4).
First, set up an equation that models this statement.
N is your variable because it’s the unknown Number.
8n-13=43
Then, add 13 on both sides so you have the variable and it’s coefficient alone.
8n-13=43
+13.+13
________
8n=56
Then, divide the variable and the coefficient by the coefficient.
8n=56
—. —
8. 8
Now you have your variable all by itself, and you have the persons number.
n=7
Your number is 7.

Yes
Domain: 1, -1, 0, -3, 3
Range: 1, -1, 6
Step-by-step explanation:
The domain is in the left oval, the range is in the right oval. To find if its a function you have to make sure the domain (left side) doesn't "cheat". One number in the domain cant have more than one number in the range (right side), BUT (for future reference) the range can cheat. As shown, the right side numbers 1 and 6 have two different arrow pointed at them. As long as the domain doesnt "cheat" it is a function
