Answer:
y=4.5x+40
16 pairs of shoes
Step-by-step explanation:
Let the target earnings be represented by y and the number of pairs of shoes that Roger sells be x hence
y=4.5x+40
The equation is therefore, y=4.5x+40.
To solve this equation, substitute the value of y with 112 hence
112=4.5x+40
4.5x=112-40=72
x=72/4.5=16
Therefore, Roger should sell 16 pairs of shoes to achieve his target earnings of $112

Answer:
The other end of the line segment is at (-8, 3)
Step-by-step explanation:
Since we know one end point and the midpoint, all we need to do is take the vector from the end point to the midpoint, and add it again to the midpoint to find the other end point:
dx = -5 - (-2) = -3
dy = -1 - (-5) = 4
-5 + dx = -8
-1 + dx = 3
So the other end of the line segment is at (-8, 3)
