Answer:
I'm pretty sure the answer is D. You can see that 6 washes is 30 dollars so that would make each wash $5 and all other answers can be proven wrong or not proven to be true.
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x -----> the number of open acres
y ----> the number of developed acres
we know that
-----> inequality A
----> inequality B
Remember that
if the number of open acres, x, can be no more than 1. then the number of open acres, x must be less than or equal to 1
Solve the system of equations by graphing
The solution is the shaded area (Note The number of acres cannot be a negative number)
The graph in the attached figure
This is because when we do verification of an
identity, we must work separately on both sides, and to see in the end
if we can get an equality. Because if we square both sides, that already means
that we assume that the equality exist in the beginning, so no need to
verify the identity.
I believe the answer is the last one (D), because if n is 33 than 33 + (33+1[34]) = 67.
