Explanation:

f(x) = (x-4)(x+2)

1) For x-intercept, y will be 0

(x-4)(x+2) = 0

(x-4) =0, (x+2) = 0

x = 4, x = -2

<u />

<u>x-intercept</u>: (4, 0), (-2, 0)

2) For vertex: x = -b/2a where ax² + bx + c

<u>Quadratic function</u>:

(x-4)(x+2)

x² +2x-4x -8

x² -2x -8

<u>vertex</u>:

x = -(-2)/2(1)

x = 1

y: (x-4)(x+2) = (1-4)(1+2) = -9

ordered pair of vertex: (1, -9)

3) For y-intercept, x will be 0

(x-4)(x+2)

(0-4)(0+2)

-8

<u>y-intercept</u>: (0, -8)

You are working as a sales clerk in a fabric store and need to determine the price on some fabric. The fabric store sells for $6

mariarad [96]

Answer:

$6.10

Step-by-step explanation:

Given the fabric store sells the fabric for $6.97 per yard

Given that a customer buys 7/8 yard of fabric.

Let the cost the customer pays be x then

$1 yard---->6.97$

$\frac{7}{8} yard---->x$

on cross multiplication we get

$x\time 1=6.97\times \frac{7}{8}$

x=6.01

Therefore the amount the customer should pay is $6.01
