Y is undefined because the line x=1 never crosses the y axis.
The reciprocal of any expression is 1 divided by that expression.Therefore, the answer for the first part is 1/(y-3).Because of the division, this will be undefined if y-3 is equal to zero, in other words, if y = 3.The reciprocal of any expression is 1 divided by that expression.Therefore, the answer for the first part is 1/(y-3).Because of the division, this will be undefined if y-3 is equal to zero, in other words, if y = 3.The reciprocal of any expression is 1 divided by that expression.Therefore, the answer for the first part is 1/(y-3).Because of the division, this will be undefined if y-3 is equal to zero, in other words, if y = 3.The reciprocal of any expression is 1 divided by that expression.Therefore, the answer for the first part is 1/(y-3).Because of the division, this will be undefined if y-3 is equal to zero, in other words, if y = 3.

y = 2x is defined everywhere (for all values of x)

The value is 1 if (x, y) = (4, 3) and 0 otherwise.

y = 2x is defined everywhere (for all values of x)
Factors are (y + 4)(y - 2) so if the original expression = 0 then y is either 2 or -4
x is the same, so 8 y is undefined
Depends what the expression is. Just plug in 8 for y in the expression and that'll do it for you.
i think it would be like this: 4:25 :: 1:6.25
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
