-0.2x^2+0.9x+0.6=y<br>What's the vertex form for this equation?

hjlf

Answer: y = -0.2(x - 2.25)² + 1.6125

<u>Step-by-step explanation:</u>

$y = -0.2x^2 + 0.9x + 0.6\\\\y - 0.6 = -0.2x^2 + 0.9x\\\\y - 0.6 =-0.2(x^2-4.5x)\\\\y-0.6+\underline{(-0.2)(2.25)^2}=-0.2(x^2-4.5x+\underline{2.25^2})\\\\y-0.6-1.0125=-0.2(x-2.25)^2\\\\y-1.6125=-0.2(x-2.25)^2\\\\y=-0.2(x-2.25)^2+1.6125$

Y = -x - 1 and y = 1/2x + k intersect at the point (-2,1). Find the value of k.

Lena [83]

Answer:

k = 2

Step-by-step explanation:

(-2,1) = (x,y) So you substitute -2 and 1 for x and y

1 = -(-2) - 1 1 = 1/2 × -2 + k

1/2 × -2 = -1 -1 + 2 = 1

k = 2 1 = 1/2 × -2 + 2

It's not specific enough to solve...so far it would only be f(3)
