X=-5 y=-8
subtract the equation and then substitute it in
Yeah, I agree with letsgoplayd. Your answer doesn't make any sense because 8164 is not a decimal. But we can look at another example:
8164.45678
In this case, the number rounded to the 4th decimal point (ten thousandths) would be
8164.45680
Because the digit after the 7 is 8, we should round the "78" part to "80".
These two rules will help:
5 or more, raise the score (add 1 to the digit, and let the digit directly behind it become 0.)
4 or less, let it rest (keep the digit, and let the digit directly behind it turn to a 0.)
Hope this helps! :)

X
38 -> 24x
x > 38 -> 31(x-38) + 912
912 = 24*38 (You will have to have 38 hours to be able to be in this part of the piece wise function)
(a + b)2 Plug in the a and b values
(2 + 3)2 Add 2 and 3
(5)2 Multiply 5 and 2
10
When a = 2 and b = 3, (a + b)2 will equal 1.) 10.
