Answer:
The answer is (-5,2)
Step-by-step explanation:
So we have 2 equations and we need to solve them by substitution.
1) y = 4x + 22
2) 4x – 6y = –32
Since we already have y isolated in equation #1, we'll use that value in equation #2:
4x - 6(4x + 22) = -32
4x - 24x - 132 = -32
-20x = 100
x = -5
Then we put that value of x in the first equation:
y = 4 (-5) + 22 = -20 + 22 = 2
The answer is then (-5,2)
Answer:
(10x)^2
Step-by-step explanation:
Answer:
The third one(-20+(n-1)*)
Step-by-step explanation:
It's correct because when you plug in one of the numbers in the list, it makes the equation equal. Example Below.
n=4
n=-20+(n-1)8
4=-20+(4-1)8
4=-20+3*8
4=-20+24
4=4
