If y=5x-3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
RUDIKE [14]
<h3>Answer: Choice B</h3><h3>(-1,-8), (0,-3), (3,12)</h3>

==========================================

Explanation:

If we plug in x = 2, then

y = 5x-3

y = 5*2-3

y = 7

Meaning (2,7) is on the function instead of (2,5). So this rules out choice A

--------------------------

If we plug in x = 1, then

y = 5x-3

y = 5*1-3

y = 2

Allowing us to rule out choice C because (1,2) is on the function instead of (1,4)

--------------------------

Now let's try x = 5

y = 5x-3

y = 5*5-3

y = 22

Showing (5,22) is on the graph instead of (5,20). We can rule out choice D.

--------------------------

The only thing left is choice B

Plugging in x = -1 leads to

y = 5x-3

y = 5(-1)-3

y = -8

We see that (-1,-8) is on the graph.

Plugging in x = 0 leads to

y = 5x-3

y = 5(0)-3

y = -3

The point (0,-3) is on the graph

Finally, plug in x = 3

y = 5x-3

y = 5*3-3

y = 12

The point (3,12) is on the graph

The points all mentioned in choice B are on the graph of y = 5x-3, so this confirms choice B as the answer.

Serggg [28]

Answer: 23.2 miles per hour

Step-by-step explanation:

He ran 100 meters in 9.63 seconds.

First convert the number of meters he ran to miles:

= 100 * 3.28

= 328 feet

= 328/5,280

= 0.062121212 miles

Convert the seconds to hours:

= 9.63 / 60

= ‭0.1605‬ minutes

= ‭0.1605‬/60

= ‭0.002675‬ hours

Speed in miles per hour is:

=  0.062121212 / ‭0.002675

= 23.22

= 23.2 miles per hour
