Answer:
d
Step-by-step explanation:
Slope intercept form: y = mx + b
y = -x + 7
x + y = 21
x + y = 21
-x -x
y = -x + 21
y = -x + 7
y = -x + 21
Parallel lines have the same slope. Here, our slope is -1
Therefore, our final answer is d.

Answer:
y = 50 + 35x we dont know how many hours they worked
Step-by-step explanation:
The height is 5 m. The area of a trapezoid is (b1+b2/2)h
Answer is Y/2=51
We start with Y=102
We can plug 102 into the equation Y/2=?
We get 102/2=?
102/2=51.
Therefore, Y/2=51
