Answer:

X = savings, p= pay per hour

X+4p = 86 - - - - (1)

X+6p=104 - - - - - (2)

Re arrange equation (1)

X=86-4p-----(3)

Substitute (3) in (2)

86-4p +6p=104

86+2p=104. (subtract 86 from both side)

2p = 18. (divide by 2 from both side)

Then p =$9

By substitute in equation (1)

X = $50

jeff wants to buy a phone card for long distance calls. he can buy a 200-minute card for $10.00 or a 300-minute card for $12.00.
Alenkasestr [34]
200 min / $10.00 = 20 minutes / dollar 

<span>300 min / $12.00 = 25 minutes / dollar </span>

<span>The cost of the 300 minute card is cheaper per minute and a better value. </span>

<span>If you don't expect to use more than 200 minutes then save your money and buy the smaller card.</span>

Convert y =(x+1)(x-9) to vertex form
IgorC [24]

Answer:

y = (x - 4)² - 25

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square.

Given

y = (x + 1)(x - 9) ← expand factors using FOIL, thus

y = x² - 8x - 9

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 8x

y = x² + 2(- 4)x + 16 - 16 - 9

  = (x - 4)² - 25 ← in vertex form
