The answer is 0. In algebra, the multiplication symbol is not used, as it would be too commonly mistaken for the letter x, which looks the same, but serves a completely different purpose. Algebra, is in short, just a way of substituting numbers for letters, to make complicated sums and equations seem more manageable. If x equals 0 and y equals 1, then it is just another way of saying 0 x 1, which is obviously 0, because 0 lots of anything, is always 0.
If Y = 0 then there is no value of X such that XY = 1.
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
That is the commutative property of equality.
xy = x ÷x y = 1
Assuming the two equations are: 3xy - 3 = 0 ............................................. 1 2xy = 0 ............................................. 2 Then from eq 1 xy = 1 from eq 2 xy = 0 That is not possible. Or, assuming the equation is 3xy - 3 + 2xy = 0 Then 5xy = 3 or y = 3/5x Substitute for any value of x to get the value of y
So far you know that: x=-8 xy=1 so xy means x times y. If you split xy. y=1/x or y=1/-8 1/-8= -0.125 You can find out that this is correct with the formula xy=1 because -0.125 x -8 is 1.
The greatest possible slope is 1.
here for least value X=2,y=3hence 2(3)-3(2)=0=0
-1/8 -8*-1/8 = 1
It equals y+1
Its value is 1 when the statement is true and 0 otherwise.Its value is 1 when the statement is true and 0 otherwise.Its value is 1 when the statement is true and 0 otherwise.Its value is 1 when the statement is true and 0 otherwise.
Just plug in the values for x and y. 4(-1) - 2(5) + (-1)(5) = -19
