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
