Step-by-step explanation:
y = -f(x)
so, everything is mirrored around the x-axis.
what was below the x-axis, is now above the x-axis, what was above is now below. and what was on the x-axis, is still on the x-axis.
pick the corner points of f(x), their x-values stay the same, their y-values flip the sign. the points on the x-axis (y = 0) stay the same of course.
and then connect the points, so that the curve is upside-down to the original.
D is your answer
1/3 of 18 is 6, so 2/3 would be 12
Answer:
Parallel
Step-by-step explanation:
The graphs of these two equations will never intersect. Hope this helps.
So, we have to divide the total amount of the profit they made by the cost per car wash. This is because we have to find the unit rate. So, the problem would be $853 divided by $5. Now the answer would be 170.6, but if you round the answer, it would be approximately 170 cars. We have to round, because 0.6 is NOT a full car, and we need to know how MANY CARS were washed. We wouldn't do anything with the $12 they spent, because the problem does NOT state anything about the amount of cash they have AFTER the supplies were bought.
