How do you solve the linear system negative 5x plus 3y equals 51 and y equals 10x minus 8 with substitutions?
5x+3y = 51 y = 10x-8 Substituting the bottom equation into the top equation: 5x+3(10x-8) = 51 5x+30x-24 = 51 5x+30x = 51+24 35x = 75 Divide both sides by 35 to find the value of x: x = 75/35 = 15/7 in its lowest terms. Substitute the value of x into the original equations to find the value of y: So: x = 15/7 and y = 94/7
How do you identify if the given equation is function or not?
A function is an equation (a relation) which has only one y-value for every x-value. If a single x-value has more than one y-value, the equation is no longer called a function.
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
In the equation y 3x 1 what is the value of y when x equals 3?
If you mean: y = 3x+1 then the value of y will equal 10
What function has an output value of 7 for an input value of 4?
You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7

What is the solution to the equation y equals -2.5?
y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.

How do you find the value of y in algebra?
You solve an equation containing y.
What is the value of the y in the equation?
Without an equality sign it is not an equation and so therefore its value can't be determined.
What is the value of y if x equals 0?
Then, y can be any value such that x = 0! If that equation doesn't contain y values, then this means that any y value work for the equation! For instance, if y = 1, then x = 0. If y = 2, then x = 0 and so on.
What is the value of x when y 4 in the equation y 6x - 20?
y=4
What y equal in the equation 82x?
Y = 82x, the value of Y will be 82 times whatever value of x that is chosen
What is the relationship between the y-intercept of the line and the equation?
It is the value of the equation y = f(x) when x = 0.
What is the x intercept when any equation has a y value of?
y must have a value of 0 at the x-intercept.
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 find the magnitude of the y-intercept?
-- In the equation of the graph, set x=0. -- Solve the equation for 'y'. -- The value you get for 'y' when x=0 is the y-intercept.
