The construction crew took
days to build
miles of road.
Therefore, in 1 day, the crew built
miles of road
=
miles of road
Thus, the required rate is
miles or
miles per day.
Since x=months,
50x=y
Where x is the number of months times the monthly charge. Y is just the output, or end value.
I hope this helps!

Answer:

Step-by-step explanation:
we would like to solve the following equation for x:

to do so isolate
to right hand side and change its sign which yields:

simplify Substraction:

get rid of only x:

simplify addition of the left hand side:

divide both sides by q+p Which yields:

cross multiplication:

distribute:

isolate -pq to the left hand side and change its sign:

rearrange it to standard form:

now notice we end up with a <u>quadratic</u><u> equation</u> therefore to solve so we can consider <u>factoring</u><u> </u><u>method</u><u> </u><u> </u>to use so
factor out x:

factor out q:

group:

by <em>Zero</em><em> product</em><em> </em><em>property</em> we obtain:

cancel out p from the first equation and q from the second equation which yields:

and we are done!
The first column. The rule for that column is y = x * -4.
