bearing in mind that an absolute value expression, is in effect a piece-wise expression, so once we remove the bars, we really end up with two siblings, one is negative, the other positive, of the same expression.

Answer:
B) 5/5
Step-by-step explanation:
5/10 ÷x = 1/2
Divide the top and bottom by 5/5
5/10 ÷ 5/5 = =1/2
If you mean axis then the answer is that the coordinate on the y axis stays the same but the coordinate on the x axis is the opposite.
For example, if the number on the y axis on quadrant 1 is 4 then if it's reflected onto quadrant two, the number will stay the same but if the number on the x axis is 4 then if it's reflected onto quadrant two, the number will be -4
Part A: Equation 1: 20x +120
Equation 2: 25x +80
( I think this is the answer)
Part B:
Answer:
38°
Step-by-step explanation:
2y+2=3y-16
18=y
3(18)-16= 54-16=38
