How do you change from standard form to slope intercept?
Solve the standard form for the dependent variable, commonly 'y'.
What is the vertex of xyz?
It all depends on what xyz is. If xyz is an arc of a curve, there will be no vertex whereas if xyz is a triangle, each of x, y and z will be a vertex.
How do you find x and y in system of equations?
The basic idea here is to look at both equations and solve for either x or y in one of the equations. Then plug the known value into the second equation and solve for the other variable.
What should be added to both sides of this equation to solve for the variable 37 -5 y?
32
What 2 number multiply to 800 and add to get -70?
Instead of just giving you the answer, I'll tell you how to solve the problem. To solve this problem, write two equations. Let one variable be x and the other y. Then you can say: xy = 800 x + y = -70 Isolate x + y = -70 for y and you get y = -70-x Then plug it back into the first equation, solve for x and plug your answer into the second equation to solve for y. Hope that helps, and let me know if you have any questions :)
What variable is used for y intercept?
you make x=0 and solve for y. for the x intercept you do y=0 and solve for x
How do you use variables to help solve math questions?
You use variable in math problems to help you solve the answer. For example, you could do 50+50=a. The (a) would be the variable. Or for that same problem you could do 50+y=100. Then the (y) would be the variable.
How do you solve for the given variable in fraction?
3/y=5/36
Solve the eqaution of a straight line with a positive slope of 2 and a positive intercept of 2 where y is the dependent variable and the variable x is the nonindependent variable?
y = 2x + 2
How do you solve systems by using the substitution method?
You solve one of the equation for one of the variables. For example, if the variables involved are "x" and "y", you might solve for "y". It doesn't really matter what variable you solve for first, so you can solve for whatever variable is easiest to solve. Then - assuming you got, for example, "y = 3x -1", in this example you would replace every "y" by "3x - 1" in the other equation or equations.
3y equals ab solve for variable y?
3y=ab. Divide by 3 to get y=ab/3
How do you solve x minus y equals 6 and x plus y equals -2?
4
How do you find the value of a variable?
you have to solve for the variable for example. 4x + 2y = 8. you would solve for y. so you subtract the 4x and you do the same to both sides and you get 2y = -4x + 8. you then divide everything by 2 to get y by itself and you end up with y = -2x + 4
How do you rewrite and solve for y 2x less than y plus 7?
your equation is this... 2x < y + 7 Now solve for y... 2x - 7 < y Since you have two variable the most you can get out of (y) is the graph and the y-intercept. the y-intercept is y > -7
How do you solve 9x plus y equals 22?
To solve the equation 9x + y = 22, you need to isolate one of the variables. You can do this by either substituting a value for one variable and solving for the other, or by rearranging the equation to solve for one variable in terms of the other. For example, if you choose to solve for y, you would subtract 9x from both sides to get y = 22 - 9x. If you choose to solve for x, you would subtract y from both sides to get 9x = 22 - y, then divide by 9 to solve for x.
How do you solve for a variable if there are more than one of that same variable in the equation For example how would I solve xyy 4 for the variable y?
Assuming you meant to insert an = between xyy and 4, then xyy=4. Divide by x to get yy=4/x. yy is y^2, so y^2=4/x. Take the square root of both sides to get y=±√(4/x)
How do you change from standard form to slope intercept?
Solve the standard form for the dependent variable, commonly 'y'.
