Answer:
9x² - 12x + 4
Division Property
Step-by-step explanation:
(3x-2)² = (3x-2)(3x-2)
using the foil method we get:
9x² - 6x - 6x + 4
combine 'like' terms to get:
9x² - 12x + 4
2x = 10 To get 'x' by itself, since it's being multiplied by 2 we must do the inverse operation which is division
If we divide one side of an equation by 2 we must do the same to the other side, giving us:
x = 10/2 which is x = 5
So the vertex formula is A(X - H)^2 + K so find the vertex and plug all numbers in
this gives you (x - 2.5)^2 -3.25 = f(x)
Answer:
y = 1/3x - 7/3
Step-by-step explanation:
y2 - y1 / x2 - x1
-1 - (-3) / 4 - (-2)
2/6
= 1/3
y = 1/3x + b
-1 = 1/3(4) + b
-1 = 4/3 + b
-7/3 = b
can you put a picture or sum i dont understand
