Carly and simon are renting formal clothes for a wedding. they found a rental company that charges a fixed fee of $90.00 and an additional fee of $21.00 per hour. which of the following linear equations shows an hourly rate of $21.00? a. y = $0.90x + $0.21 b. y = $90.00x + $21.00 c. y = $21.00x + $90.00 d. y = $0.21x + $0.90

C. y = 21x+90

Step-by-step explanation:

Let x be the number of hours. Each hour costs 21 dollars, so the cost of all the hours would be 21x. Then add a fixed fee of 90 to get C, y = 21x+90

The answer should be C

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
