Answer:
(-2, 4)
Step-by-step explanation:
y = -3x - 2
y = -x +2
=> -3x - 2 = -x +2
-3x + x = 2 + 2
-2x = 4
x = -2
-x + 2 = y
2 + 2 = y
4 = y
Both variables (x) are 3.
4×3=12
12-2=10
16×3=48
48-8=40
3 fits the variable of the missing number.
#2 #3 and #5 I think but I could be wrong. Good luck!
So in matt's equation, he made a mistake in the a transision from line 2 to line 3
in line 2: -4(-2)2
in line 3: -4(4)
the mistake is that -2 times 2 is not equal +4 it is equal to -4
also from lines 5 to 6 he made a mistake in order of opperations (mulit division then addition and subtract)
line 5: -10+30/5
line 6: 20/5
so he first subtracted 10 then divided, he should have divided then subtracted
so the equation should have equaled
Karen used the correct (-) times (+) property and the order of operations
so Karen is correct and Matt is wrong.
