Answer:
D.
Vertex form: f(x) = 2/3(x + 3)^2 - 6.
Standard form: f(x) = 2/3x^2 + 4x.
Step-by-step explanation:
The vertex is at (-3, -6) so the vertex form is
y = a(x - (-3))^2 - 6
y = a(x + 3)^2 - 6
Now we find the value of a by substituting x = 0 and y = 0:
0 = a(0 + 3)^2 - 6
9a = 6
a = 2/3.
Vertex form is y = 2/3(x + 3)^2 - 6.
Convert to Standard form:
Multiply through by 3:
3y = 2(x + 3)^2 - 18
3y = 2x^2 + 12x + 18 - 18
3y = 2x^2 + 12x
y = 2/3x^2 + 4x.

boo divide 16.17 by 7 to find 1 pound, i dont get y every time i refresh ur questions pop up looooool XD
Answer:
40 ounces
Step-by-step explanation:
a pound is 16 ounces so 2 and a half is 40 ounces
Answer:
the answer is 151 paper clips
Step-by-step explanation:
Because in one pound = 453.592 grams
Then you will divide 453.592 by 3 and you will get 151
which means there are 151 paper clips in 1 pound
X1= -9, x2 = -1. sooo the third one
