Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
Answer:
y = (x - 2)² - 4

Square of five = 5^2 = 5 x 5 = 25
answer
c) 25
Answer:
x=-2
Step-by-step explanation:
If the question is asking for the intersection point, the answer is x=-2 or (-2,1) depending on if the teacher is asking for the intersection or value of x where it itersects
If the question is asking what the equation of the parabola is I would guess it is (x+1/2)^2 -4
I say go with x=-2 though
