Which of the following ordered pairs make this equation true?
y = 3x + 2
B. (8,2)
A. (2, 2)
C, (3, 11)
D. (5, 1)

c

Step-by-step explanation:

plug in

y=3x+2

11 = 3(3) + 2

11=11

she must start the work by 11:10 A.M. in order to get ready at 2:00 P.M.

Step-by-step explanation:

Time taken by Vivian to mow the lawn = 1 hour 15 minutes

Time taken to trim some bushes = 40 minutes

Time taken to put down some much = 25 minutes

Time taken to get shower and dressed = 30 minutes

Total time taken by Vivian = 1 hour 15 minutes + (40 + 25 + 30 ) minutes

                                            = 1 hour 15 minutes + 95 minutes

                                            = 1 hour ( 15 + 95) minutes

                                            = 1 hour 110 minutes

60 minutes = 1 hour

110 minutes = 1 hours 50 minutes

⇒ Total time taken by Vivian = 2 hours 50 minutes

Time upto which Vivian needs to get ready = 2 : 00

So, she must start the work by : 2 - 2 hours 50 minutes

                                                  = 11 : 10 a.m.

Hence, she must start the work by 11:10 A.M. in order to get ready at 2:00 P.M.
