Which row of the input/output table is incorrect? y = 2 x - 3 x y Row A 3 3 Row B 5 7 Row C 7 11 Row D 10 15 Row B Row C Row A R
Dmitry_Shevchenko [17]

The row of the input/output is incorrect is Row D.

<h3>What is equation?</h3>

Given equation: y = 2x - 3

For, row A:  

x = 3

y = 2x - 3

So,

y = 2(3) - 3

y = 3, which is correct

For row B:

x = 5

y = 2x - 3

So,

y = 2(5) - 3

y = 7, which is also correct.

For row C:

x = 7

y = 2x - 3

So,

y = 2(7) - 3

y = 11, which is also correct.

For, row D:

x = 10

y = 2x - 3

So, y = 2(10) - 3

y  = 17, which is incorrect.

Hence, the row of the input/output is incorrect is Row D.

Help me please number 16
Virty [35]

200 steps in an hour would be 800 steps in 4 hours.

I see it asks for a table so the table would be...

1 hour - 200 steps

2 hours - 400 steps

3 hours - 600 steps

4 hours - 800 steps

5 hours - 1000 steps

and the pattern is that every 1 hour he can walk 200 steps.

An equation would be mx = 200m.
