In order to answer that, you need to know how 'x' and 'y' are related to
each other. In the book that you copied this from, there was most likely
an equation with the question. It was there to show how they're related.
Without knowing the specific relationship between x and y, it is impossible to determine the value of x when y is 150. The values of x and y could be related in a variety of ways, such as linear equations, quadratic equations, or exponential functions. To find the value of x when y is 150, you would need to be given the specific equation or relationship between x and y.
Oh, dude, it's like a math problem, but okay. So, if y is 150 and x is not given, we can't really solve for x without more information. It's like trying to find your keys in the dark without a flashlight, you know? So, without knowing the relationship between x and y, we're just stuck in math limbo.
The slope of this equation is 10 and the y intercept is 150
Y=sin X is a function because for each value of X, there is exactly one Y value.
The value of x + y is indeterminate. You need the values of both x and y to determine x + y.
In most cases, x is independent and y is dependent. That is, you choose the value of x, but this x-value will decide the corresponding y-value.
It will be 16.
x-y = 120 x+y = 150 add equations: 2x = 270 x = 135 y = 15
15 (x = 135)
15
Y=sin X is a function because for each value of X, there is exactly one Y value.
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.
X = 135 and y = 15 Solved by addition and substitution
Let x be the number of boys and y be the number of girls. That gives us two equations: x + y = 150 and .25x + .5y = 49.25. Solve the first equation for x: x = 150 - y. Plug that value of x into the second equation: .25(150 - y) + .5y = 49.25 Solve for y: 37.5 - .25y + .5y = 49.25, .25y = 11.75, y = 47. Thus, there are 47 girls. Plug this value back into the first equation to get the number of boys: x + 47 = 150, x = 103.
If your system is x - y = 120 x + y = 150 I would use elimination. Adding the two equations together gives us 2x = 270 and dividing by two tells us that x = 135. Plug x back into either equation to find y: x + y = 150 135 + y = 150 y = 15 So x = 135 and y = 15.
Oh, what a lovely question! When x is 3, we simply substitute x with 3 in the equation to find the value of y. It's like adding a happy little tree to your painting - just plug in 3 for x and see what beautiful value of y comes out!
First you need to know that the equation you are looking for is y = kx^2. Then you need to substitute the numbers in: y = kx^2 150 = k5^2 150 = k25 6 = k Now that you know k, resubstitute it for the new value of y when x = 4: y = kx^2 y = (6)(4)^2 y = (6)(16) y = 96
There are more than 1 set of values that will work. The value's of "x = 1" and "y = -1.5" will work and therefore the values "x = 100" and "y = -150" will work as well. In other words take any number you want for the value of x and multiply that number by negative 1.5 (-1.5) to get the value of y. y = (x multiplied by -1.5)
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
