Assume y = 4.5. Then, the value of x is infinite! Why?
We are given the expression y = 4.5. What if we take x = 1? Then, y = 4.5. What if x = 2? Then, we also have y = 4.5. Same pattern for other x values.
Therefore, there are infinitely many solutions for x.

The value of x is not infinite, it is indeterminate. The number of possible values of x is infinite.

What is the value of x in the equation x and ndash y 30 when y 15?
x is 45.
Each Y value equals the corresponding X value on a 45 degree line?
45 degrees with respect to what?
Can a pair with the same x and y value be a function?
Yes; a line at 45 degrees.
What is the value of the expression 5X-2y when x equals 9 and y equals 4?
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value
What is the value of x in the equation x y 30 when y 15?
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
How do you solve for y and x when x plus y equals 45?
There are infinitely many solutions as x + y = 45 defines a straight line. Pick a value for x and you can calculate the y value so that x + y = 45. It can be rearranged to get y in terms of x: x + y = 45 → -x + x + y = -x + 45 → y = -x + 45 It is a line with slope -1 and intercept 45. You can substitute any value for x and the corresponding y value will be found. eg x = 1 → y = -1 + 45 = 44 x = 25 → y = -25 + 25 = 20

What does x - y?
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
How do you find the sum of xy when x 45 and y1094?
If you mean "What is the answer to x*y when x=45 and y=1094?" then the answer is 49,230. If you mean "What is the answer to x+y when x=45 and y=1094?" then the answer is 1,139.
Can a pair with the same x and y value be a function?
Yes; a line at 45 degrees.
If the difference of the sum and difference of two numbers is 90 and if the sum of the sum and difference is 162 what are the numbers?
The answer is 45 and 81. To find it out you need to use double algebra. 1. (x+y)-(x-y)=90 x-x=0 y+y=2y/2= 1y=y 90/2= 45 y=45 2. (x+y)+(x-y)=162 y-y=0 x+x=2x 2x/2= 1x=x 162/2=81 3. check your work x+y-x-y=90 81+45-81-45=90- x+y+x-y+=162 81+45+81-45=162 81+45= 126 81-45=36 126+36=162 That is how you find the answer.
What is the value of y when the value of x is 3?
It depends on the relationship between x and y.
What is the value of the expression 5X-2y when x equals 9 and y equals 4?
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value
What is the value of x in the equation x y 30 when y 15?
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
What times what equals 2025?
There are infinitely many possible answers. x ≥ 45 and let y = 2025/x Then xy = x*2025/x = 2025 and, since x ≥ 45, then y ≤ 45 so that (x, y) is always distint from (y, x). Then, since these are infinitely many choices for x, there are infinitely many answers.
What is the value of x plus y?
The value of x + y is indeterminate. You need the values of both x and y to determine x + y.
