Answer:
1
Step-by-step explanation:
So when we raise a number to the zeroth power, that means we multiply the number by itself zero times - but that means we're not multiplying anything at all! ... In short, 0 is the only number such that for any number x, x + 0 = x.
hope this helps
solve for "K", to see what "K" is, or the "constant of variation",
once you found K, plug it back in y=Kx, and that's the equation

Answer:
original number = 53
Step-by-step explanation:
In two digits number:
Let the tens place digit be x and units place digit be y.
So,
Original number = 10x + y
Number obtained after reversing the digits = 10y + x
According to the first condition:
x + y = 8.... (1)
According to the second condition:
10y + x = 10x + y - 18
10y + x - 10x - y = - 18
9y - 9x = - 18
-9(x - y) = - 18
x - y = - 18/(-9)
x - y = 2.......(2)
Adding equations (1) & (2), we find
x + y + x - y = 8 + 2
2x = 10
x = 10/2
x = 5
Plug x = 5 in equation (1), we find:
5 + y = 8
y = 8 - 5
y = 3
10x + y = 10*5 +3 = 50 + 3 = 53
Hence, original number = 53
