Answer:
Step-by-step explanation:
The point of intersection of
and
is the solution of the two equations.
We add equation (1) and equation(2) to get,
We put 
into equation (1) to get,
Therefore the line passes through the point, 
.
The line also passes through the point of intersection of
and
We subtract equation (3) from equation (4) to obtain,
We substitute this value into equation (4) to get,
The line also passes through
The slope of the line is
The equation of the line is
is the required equation
Given that the value of $50000 car decreases by 4% per year, the value after 3 years will be given by exponential form:
y=abˣ
where:
a=initial value
b=decreasing rate
x=time in years
from the information:
a=50000, b=0.96, x=3
thus
y=50000(0.96)³
simplifying we get:
y=$44, 236.8
~$44237

Dist from slide to fountain: 200 ft, because they are 2 grid spaces away from each other (y axis, coordinate (-2, 0) to coordinate (-2, -2))
dist from fountain to swings is 700 ft, because they are 7 grid spaces away from each other (x axis, coordinate (5, -2) to (-2, -2))
