What are the two numbers if the sum of two numbers is 82 and the difference is 36?
x = 59y = 23Let:x = the first numbery = the second numberx + y = 82 -- equation (1)x - y = 36 --- equation (2)By Elimination:x + y = 82x - y = 36=========2x = 118 2x/2 = 118/2x = 59x + y = 82y = 82 - xy = 82 - 59y = 23check:x - y = 3959 - 23 = 3636 = 36Let x = 1st numberlet y = 2nd numberX + Y = 82X - Y = 36add above equations2X = 118X = 59Y = 23
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.
If the equation is x equals 2 what is y?
That makes no sense, there is no y in the equation so y cannot equal anything.
How do you find the y-intercept of the graph of the equation?
Set 'x' equal to zero, and solve the remaining equation for 'y'.
What does Y equal in the equation 6 x 0.5 25 x Y?
y=5
What is an equation for nonlinear?
an nonlinear equation can be y=3x m dose not equal 7
Is y a function of x in this equation 5x-3y-150?
That is not an equation because there is no equal sign. In order for y to be a function of x, y must equal the rest of the values. So assuming that your expression was equal to 0. To make y a function of x, add 3y to both sides and then divide the equation by 3. y=5/3x-50
How do you find the x and y-intercepts without using a graph?
-- Take the equation. -- Say to yourself, "At the x-intercept, y=0". Set 'y' equal to zero, solve the equation for 'x', and you have the x-intercept. -- Take the original equation again. -- Say to yourself, "At the y-intercept, x=0". Set 'x' equal to zero, solve the equation for 'y', and you have the y-intercept.
What is the y intercept and slope in this equation y equal x?
The y-intercept is 0 and the slope is 1.
Why is the difference between expression and equation?
Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y
What is y in y equal 4x-2?
Sorry, but it is impossible to solve this equation by itself. Since you have two unknowns, you need two equation.
For the equation y equals 5 plus 6x what does y equal when x is 4?
