Y=5x would give them the money they earn after all the car washes. In order to calculate when they make a profit, you could use:
5x>75
So, you can divide 75 by 5 to get that they need to wash at least 15 cars to earn all the money they spent on setup, and to make a profit, they must wash more than that.
21 / \

Answer:
y + 8 = 2x + 2
Step-by-step explanation:
Use the points given to find the slope. Divide the difference in y-values by the difference in x-values.
(-1) - (-7) = 6
5 - (-8) = 3
6/3 = 2
The slope is 2.
Now, pick one of the points to put in point-slope form. It doesn't matter which. You will get the right answer either way. I will use (-1, -8).
y - y₁ = m(x - x₁)
y - (-8) = 2(x - (-1))
y + 8 = 2(x + 1)
y + 8 = 2x + 2
Answer:
A
Step-by-step explanation:
Since DA can be considered a line the whole value of it is 180 degrees. So you do 180-105 which equals 75. You then add 75 to 67 which is equal to 142. The value of a triangle is 180 so you would do 180-142 and you would get 38. Thus, X is equal to 38 degrees.
