Answer:
The equation of the parabola is:
Step-by-step explanation:
The equation of the parabola is:
Where 
is equal to the distance between focus and vertex. Then,
Lastly, the equation of the parabola is:
5 x 4= 20
8 x 2 = 16
36 + 2 + 2 = 40
40 square inches
Answer:
Part A: one solution:
Part B: x = 3, y = 4.
Explanation:
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.
3x + 4 = 2x + 27
3x - 2x = 27 - 4
x = 23 <==
