What is the vertex of g(x)=8x^2-64x

2 answers:

8 0

The (x,y) point of the vertex is usually labelled as:
Vertex = (h, k)
h = -b / 2a
h = --64 / 2*8
h = 64 / 16
h = 4


To get “k”, input the “h” value into the equation.
k = 8*(4^2) -64*4
 k = 8*(4^2) -64*4
k = 128 -256
k = -128
Vertex = (4, -128)

To find the slope, use the simple rule rise/run. The change in the y value over the change in the x value. The y changes by -1 when the x changes by positive 2. Therefore, the slope is -1/2.

The length of a rectangle is three times its width. The perimeter of the rectangle is at most 112cm. Which inequality models the

miss Akunina [59]

Answer: w ≤ 14 cm , L ≤ 42 cm

Step-by-step explanation:

width (w): w

Length(L): 3w

Perimeter (P) = 2w + 2L

P ≤ 112

2w + 2L ≤ 112

2(w) + 2(3w) ≤ 112
