y=1 and x=4 means that in an equation/sum, if y or x are written it means they represent those numbers.
if y=1 and x=4, then 4y=4=x
x - 4 = 1 4 + 1 = x Therefore, x = 5
Evaluate x/y when x = 4 and y = 4. x/y = 4/4 = 1/1 = 1
One possible expression is [ 1/(x - 4)+ 1/x ].
4. 1 x 4 equals 4 - - 9 x 4 equals 36
-1/2
x equals 7
If X+Y=5;X=4, then x=4 and y=1
x = -1/4
When x = 1 then y = 4
x-1 = 4 Add 1 to both sides: x-1+1 = 4+1 x = 5
Zero factorial is one because n! = n-1! X n. For example: 4! = (4-1) X 4. If zero factorial was zero, that would mean 1! =(1-1) X 1 = 0 X 1=0. Then if 1!=0, then even 999! would equal zero. Therefore, zero factorial equals 1.
