X-4y=-18
an easy way is to solve for oone variable
solve for x
add 4y both sides
x=4y-18
when y=1, x=-16
when y=0, x=-18
when y=2, x=-10
(x,y)
so some orderd pairs are
(-16,1)
(-18,0)
(-10,2)
A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;
x = 1, y = 5.0125
B) The possible solutions of the given equation will be; x = 3.11 or -3.11
C) The solution to p(x) = g(x) is; x = 0 and y = 0
<h3>How to find the solution to simultaneous equations graphically?</h3>
When we are trying to solve two simultaneous equations, there are three methods we can use namely;
1) Elimination Method
2) Substitution Method
3) Graphical Method
Now, we see that we are to use the graphical method from the given graph.
Now, the solution to the given pair of equation will be the coordinates of the points where both graphs intersect.
A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;
x = 1, y = 5.0125
B) The possible solutions of the given equation will be the point where f(x) = 0 which is where the line crosses the x-axis and so we have;
x = 3.11 or -3.11
C) The solution to p(x) = g(x) is the coordinate;
x = 0 and y = 0

Answer:
Step-by-step explanation:
Opposite angles equal each other, so angle B and angle D are equal.
2x = 74
x = 37
C
P(n) = total monthly profit
Let n = number of markdowns
Total profit = (Markup per car)(Number of car sales)
P(n) = (2000 − 400n)(20 + 6n)
<span>P(n) = −2400n2 + 4000n + 40,000</span>
