Answer:

x=−3 and y=−2

Step-by-step explanation:

-5x+4(-2x-8)=7

-13x-32=7

-13x-32+32=7+32

-13x=39

divide both sides by -13

x=-3

substitute x for -3

-2(-3)-8= -2

y= -2

Answer:

2. Adjacent and formed a linear pair

3. Adjacent

4. Not adjacent

Step-by-step explanation:

In essence, adjacent angles are two angles side by side. Two adjacent angles can form a linear pair when they are created by two lines intersecting. So, in broad terms, they are adjacent on a flat plane (or a straight line), and together they make a 180° angle.
