Use the function rule, y = 2x + 5 to find the values of y when x = 1, 2, 3 and 4 Write the answers as ordered pairs that would be used to graph the function

(1,7) (2,9) (3,11) (4,13)

Step-by-step explanation:

The function is y = 2x + 5. To find the y coordinates we will insert the values 1, 2, 3, and 4 for x.

y = 2(1) + 5

y = 7

So the first coordinate would be (1,7)

y = 2(2) + 5

y = 9

Second coordinate will be (2,9)

y = 2(3) + 5

y = 11

Third coordinate will be (3,11)

y = 2(4) + 5

y = 13

Fourth and final coordinate will be (4,13)

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
