Suppose a parabola has an axis of symmetry at x = -8 , a maximum height of 2, and passes through the point (-7, -1). Write the e
lidiya [134]
As it has a maximum value the coefficient of x^2 will be negative

The vertex will be at (-8,2)  so in vertex form it is

y = a(x + 8)^2 + 2
and as it passes through (-7,-1) we have:

-1  = a(-7+8)^2 + 2

-1 = a + 2  so a = -3

answer is  y = -3(x + 8)^2 + 2

in standard form this is y = -3x^2 -48x  - 190

Bill is shopping for folders, notebooks, and pencils for the first day of school. A notebook costs 4 times as much as a folder.
spin [16.1K]

<u>Answer:</u>

$14

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

Assuming the cost of folder to be x, then the cost of notebook will be 4 x and the cost of set of pencils will be 2 x.

Cost of the folder = $2

Cost of notebook = 4 × 2 = $8

Cost of pencil = 2 × 2 = $4

Total cost of 1 folder, 1 notebook and 1 set of pencils = $2 + $8 + $4 = $14
