abruzzese [7]3 years ago
5 0

Answer:

x = ±6

Step-by-step explanation:

x^2/4=9

Multiply by 4 on each side

x^2/4 *4=9*4

x^2 = 36

Take the square root of each side

sqrt(x^2) = ±sqrt(36)

x = ±6

Assume that the value of an automobile is inversely proportional to its age. If it is worth $3,000 when it is two years old, wha
Sholpan [36]
As age increases, the value decreases. Older = less valuable 

Value = k x 1/age
$3,000 = k x 1/6 

To find k, use $3,000 = k/2
k = $6,000

Substitute $6,000 for k

$3,000 = $6,000 x 1/6 = $1,000

The weekly sales commission at Company X is 2 percent of the first $2,000 of weekly sales plus 15 percent of the weekly sales in
Marizza181 [45]

Answer:

A) $5900

Step-by-step explanation:

For company X, we have 2% on the first $2000 sales

= (2/100) * 2000

= $40 commission

The remainder = $5000 - $2000

= $3000

For the remainder $3000, we have a commission of 15%

= (15/100)*3000

= $450

The total sales of company X = 450 + 40

= $490

For Y, we have 5% in the first $2000 sale

= (5/100) * 2000

= $100 commission

After the remaining $3000, the commission = 490 - 100

= $390(which is 10% above $2000 sales)

If $390 is 10%, then 100% = $3900

Total sales will be $2000 + $3900

= $5900(A)
