Luke earned $54 for 3 lawns
So each lawn = $54/3 = $18
After mowing 7 lawns =
7 X $18 = $126
For this case we have the following function:

By the time the stone is thrown, x = 0.
We must evaluate this value of x in the function.
We have then:
Answer:
The height of the stone at the time is thrown is given by:
h (0) = 15 meters
The answer is B u put them all in a fraction and put them in simpliest form and all the answers in B come up to 7 over 8
Answer:
Option C (1, 0)
Step-by-step explanation:
We have a system with the following equations:

The first equation is a parabola.
The second equation is a straight line
To solve the system, substitute the second equation in the first and solve for x.

Simplify

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.
These numbers are -1 and -1
Therefore

Finally the solutions are
