Y= 3( x -2 )² - ( x-5 )² = 3 ( x² - 4 x + 4 ) - ( x² - 10 x + 25 ) =
= 3 x² - 12 x + 12 - x² + 10 x - 25=
= 2 x² - 2 x - 13 =
= 2 ( x² - x + 1/4 - 1/4 ) - 13 =
= 2 ( x - 1/2 )² - 1/2 - 26/2 = 2 ( x - 1/2 )² - 27/2
Answer: D)
Answer:
x = 3 n, y = -2 n, n element Z
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First cuz the y-intercept is 3 so not B or D
And the slope is -2/3
so the answer is C.
i'm not really sure about the slope part.
