Answer:
(-3, 3)
Step-by-step explanation:
The equation of line AB is
Since the y-intercept of the given line is (0,2), the line AB and the given line intersect at (0,2).
By definition, (0,2) is the midpoint of AA', where A' is the image of A after the reflection.
So, the coordinates of A' are (-3, 3)
1) | x - 2| + 3 = 7
2) |x - 2| = 7 - 3
3) |x - 2| = 4
4) x - 2 = 4 and x - 2 = - 4. Then the answer is x - 2 = - 4

Answer:
The plumber worked 50 hours, and his assistant worked 25 hours.
Step-by-step explanation:
Since a plumber and his assistant work together to replace the pipes in an old house, and the plumber charges $ 30 an hour for his own labor and $ 20 an hour for his assistant's labor, and the plumber works twice as long as his assistant on this job, and the labor charge on the final bill is $ 2000, to determine how long did the plumber and his assistant work on this job the following calculation must be performed:
40 x 30 + 20 x 20 = 1200 + 400 = 1600
50 x 30 + 25 x 20 = 1500 + 500 = 2000
Therefore, the plumber worked 50 hours, and his assistant worked 25 hours.
