Answer:
No solution
Step-by-step explanation:
What you have to do is think of two numbers that when times together it equals -1 and when added together it equals -1.
There is no number that can come out to that, so your answer is:
no solution
Answer: B) neither
================================================
Let's isolate y in the first equation. This way we can find the slope.
x-2y = 4
-2y = 4-x
-2y = -x+4
y = (-x+4)/(-2)
y = -x/(-2) + 4/(-2)
y = (1/2)x - 2
This matches with y = mx+b form with m = 1/2 being the slope.
The slope of y = 2x-2 is m = 2
------------------------------
The slope of the first line is 1/2 and the slope of the second line is 2.
Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.
Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.
This leads to B) neither as the final answer.
Answer:
1/2(n+7)
the sum of n and 7 is (n+7). to half it just put 1/2 in front of the parentheses. :)
