Question

What the input and output is

Answer 1

Hello from MrBillDoesMath!

Answer:

Rule: Y  = 5x - 3

Table Line 4: Y (output) = 37

Table Line 5: X (input) = 10

Discussion:

This one had MrBill going for a while!  The rule appears to be

Y =  5 * x - 3

Check it out! Substitute some table values (input) and check the (output) values.

Table line 4: Y(8) = 5 * 8 - 3 = 40 - 3 =  37  (Output)

Table line 5: If Y = 47 = 5*x -3   =>    add 3 to both sides

                               47 + 3= 5x   =>    as 47 +3 = 50

                               50      = 5x   =>    divide both sides by 5

                                x        = 50/5 = 10 (input)

                       

Thank you,

MrB
