Identify the "a, b, c" values, find the axis of symmetry (AOS), and plug in the x-coordinate to find the y-coordinate.
a, b, c: y = ax² + bx + c → a = 2, b = -4, c = 1
AOS: x =
=
=
= 1
y-coordinate: y = 2x² - 4x + 1 = 2(1)² - 4(1) + 1 = 2 - 4 + 1 = -1
Answer: (1, -1)

Step-by-step explanation:
x = price of 1 bush
y = price of 1 flower
12x + 30y = 240
7x + 10y = 125
the easiest approach is now to e.g. multiply the second equation by -3 and then add both equations, and then solve the result for x.
12x + 30y = 240
-21x - 30y = -375
-----------------------------
-9x 0 = -135
-9x = -135
9x = 135
x = 15
7x + 10y = 125
7×15 + 10y = 125
105 + 10y = 125
10y = 20
y = 2
so, each bush costs $15, each flower costs $2.
