<span> x − 2y = −1 => x = 2y -1
2x + y = −12
2(2y - 1) + y = -12
4y - 2 + y = -12

Answer:
0
Step-by-step explanation:
Your slope would be 0. To find the slope of a line given two points, you find the change in y over the change in x.
In this case, the change in y was 6 - 6 which equals 0.
The change in x was -5 - 2 which was -7.
Since your numerator is 0, 0 divided by anything is automatically equal to 0 no matter what the denominator is.
Therefore, your answer would be 0.
I hope this helped :)

Answer:
The length of LM,hypotenuse is 55.866ft
Step-by-step explanation:
Given that LN=39ft and MN=40ft so you can solve it using Pythogoras' Theorem:
side²+side² = hypo²
LN² + MN² = LM²
hypo² = 39²+40²
= 3121
LM = √3121
= 55.866ft (3d.p)
This conjecture is false, A and C don't have to be complementary angles.
Let Angle A be 100 and Angle B be 80 degrees. They are supplementary (sum of 180).
Let Angle C be 100 and Angle B is still 80 degrees. They are supplementary.
However, Angle A and Angle C are not complementary (sum of 90).
