What is the value of x and y in x plus y equals -7 x-y equals 1?
-6
What is the output value for y in the y equals 5x plus 3 function when the input value of x equals 2?
y = 5x + 3When x=2,y = 5(2) + 3 = 10 + 3 = 13
What happens to the value of y when the value of x changes in y equals 4x?
y = 100 - 4x ( a ) Find the value of y when x = 20.
What is y when x is three?
In mathematics, when we have an equation with two variables like y = f(x), we can find the value of y when x is three by substituting x = 3 into the equation. Without the specific equation provided, it is impossible to determine the value of y when x is three. The solution would depend on the function or relationship between y and x given in the equation.
Y equals x plus 3 and 3x-y equals 5?
Solve this simultaneous equation using the elimination method after rearraging these equations in the form of: 3x-y = 5 -x+y = 3 Add both equations together: 2x = 8 => x = 4 Substitute the value of x into the original equations to find the value of y: So: x = 4 and y = 7
If 2 x y 7 what is the value of y when x 3?
if 2x + y = 7, what is the value of y when x = 3?
When Santana is plotting points on a graph. The ratio of y y -value to x x -value is 3 3 to 4 4 for each point. What will be the x x -value of a point with a y y -value of 12 12?
It will be 16.
if x = 3 and y = 8 then what is the value of x + y?
11
Is y equals x-3 a function?
y = x - 3 is a linear function where for each x-value we find one and only one y-value.
What two numbers can you multiply to get -3?
Let one of the numbers be x and other be y. According to question: xy = -3 Put any value of x then value of y = -3/x. Let us say x = 1 then y = -3/1 = -3. And if x = 3 then y = -3/3 = -1. So for any value of x(except 0) we get a value of y. So there are infinitely many solutions of the given equation.
Does x-3 and y-3 represent the same value?
0
Is the value of y equal to 3 times the value of x?
Then y = 3x.
Substituiotion method to find the value of y y equals 2x plus 5 x plus y equals 4?
y = 2x+5 x+y = 4 Substitute the value of y into the second equation: x+2x+5 = 4 x+2x = 4-5 3x = -1 Divide both sides by 3 to find the value of x: x = -1/3 Substitute the value of x into the original equations to find the value of y: x = -1/3 and y = 4 and 1/3
Which function has a y-value of 6 if the x -value is 3?
3
What is the value of x and y in 8x equals 6y?
8x = 6y (8/6)x = y (4/3)x = y Let x = 3, 6, and 9, then y = 4, 8, and 12. So that for any value of x, you will find a correspoinding value for y.
What is the answer Y and x have a proportional relationship and y 15 when x 3. What is the value of x when y 4?
x is 0.8
What is the value of the expression x equals 4 and y equals 3?
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
