Answer:
y = 2(x - 2)² + 3 vertex form
y = 2x² - 8x + 11 standard form
Step-by-step explanation:
Vertex form
y = a(x - h)² + k
(h, k) = (2, 3)
y = a(x - 2)² + 3
To find "a" plug in the y-intercept (0, 11)
11 = a(-2)² + 3
11 = 4a + 3
Subtract 3 from both sides
8 = 4a
a = 2
y = 2(x - 2)² + 3
Expand
y = 2(x² - 4x + 4) + 3
y = 2x² - 8x + 11
Answer:
x= 13/22
Step-by-step explanation:
you can substitute y= 34 x on the second equation
34x = -54x +52 add 54x to both sides
34x +54x = -54x +54x +52
88x = 52 divide both side by 4
22x = 13 divide both sides by 22
x= 13/22
