Answer:
y=-9
Step-by-step explanation:
If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22
We can solve for multiplication first:
4-2y=22
Then we can subtract four on both sides, canceling out the four on the left side:
-2y=18
Now to isolate y, we divide both sides by -2, resulting in the solution:
y=-9

The expression that represents the distance between -3 and 5 on the number line is “-3-5”.
Recall that
Let
, so that
Since the angle
lies in the second quadrant, you know that the cosine must be negative, so
