PLZ HELP ASAP!! 100 points!!! <br><br> Are these examples of direct variation? Please explain
Grace [21]

Answer:

mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other. 

8 - direct variation Since the equation can be written in the form y=kx. , y varies directly with x and k. The constant of variation, k, is 3.25

9 - When solving for y, y=5x-9 so y doesn't vary directly with x.

y doesn't vary directly with x

10 - direct variation Since the equation can be written in the form y=kx, y varies directly with x and k. The constant of variation, k, is -2.4

A local diner purchased a jukebox for 9400. The business makes a down payment of 1000 and agrees to pay 36 payments of 275 per m
Rina8888 [55]

Answer:

Finance charge = $1500

Step-by-step explanation:

Cost price of  jukebox = $9400

Down payment made by a local diner = $1000

Balance amount to be paid = 9400 - 1000 = $8400

In order to pay the balance amount diner agreed upon the installments = $275 per month for 36 months

Total amount to be paid in 36 months = 275 × 36 = $9900

So extra payment done = Total balance amount - Amount paid in 36 installments

= 9900 - 8400

= $1500

Therefore, finance charge paid by the diner was $1500.
