Question

A fan blade spins at a constant rate. This spinning is known as revolutions. ​The equation y=750x ​represents the number of revolutions (y) the fan blade makes in x minutes. List ordered pairs, (x,y), to represent the number ​of revolutions the fan makes for minutes 0,1,2, ​and 3. ​

Answer 1

Answer:

(0,0)

(1, 750)

(2, 1500)

(3, 2250)

Step-by-step explanation:

To list the ordered pairs (x,y) we need to calculated the number of revolutions for minutes 0, 1, 2 and 3.

To calculated the number of revolutions for 0 minutes, we need to replace x by 0 in the initial equation and solve for y as:

y = 750*x

y = 750*0

y = 0

It means that our first ordered pair is (0,0), because when we replace x by 0 we get y equal to 0

At the same way, if we replace x by 1, we get:

y = 750*x

y = 750*(1)

y = 750

So, our second ordered pair is (1, 750)

Then, replacing x by 2, we get:

y = 750*x

y = 750*(2)

y = 1500

So, our third ordered pair is (2, 1500)

Finally, replacing x by 3, we get:

y = 750*x

y = 750*(3)

y = 2250

So, our last ordered pair is (3, 2250)
