Find three different ordered pairs that are solutions of the equation y equals 2x-1?
3
Find the inverse variation equation if x equals 5 when y equals 9?
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
How do you find the gradient of y equals 2x plus 3?
It's 2. your equation is y=mx+b, so the gradient, or slope, is the "m" in the equation.
Find the equation of the line tangent to the graph of y equals cos2x at x equals pi divided by 4?
0.5
By inspection find a particular solution to y'' plus 2y equals 10?
y = 5
How many solutions are there in the equation 2x equals 10?
There is one solution. To find it, divide both sides of the equation by 2. This leaves you with x=5, where 5 is your solution.
Suppose x equals 5 is a solution to the equation 4zx plus 1 equals j where z and j are constants. Find a solution to the equation 8zx plus 5 equals 2j plus 3?
It is also x = 5 8zx + 5 = 2j + 3 → 8zx + 2 = 2j → 4zx + 1 = j Which is the first equation, which has a solution x = 5.
Can anyone help solve this equation 5x y equals 10?
Nobody can help you find a solution until you get another equation to go along with this one. Your equation has two variables in it ... 'x' and 'y' ... so it has no unique solution all by itself.
How do you know if a quadratic equation will have one two or no solutions How do you find a quadratic equation if you are only given the solution Is it possible to have different quadratic equation?
Draw the graph of the equation. the solution is/are the points where the line cuts the x(horisontal) axis .
Solve each equation. Check the solution. You may find a model helpful.5 a equals 100?
(Since 5 times 20 does equal 100, the solution is correct.
What is it called when you find the answer to an equation?
The solution
How does square root work?
The idea is to find a number which, when square, equals the given number. For example, asking for the square root of 100 means solving the equation x2 = 100. The solution, in this case, is 10. (Minus 10 is also a solution, but the term "square root" refers to the positive solution in this case.)The idea is to find a number which, when square, equals the given number.

How do you solve 3a plus b equals 1 and a plus b equals to find a common solution?
The second equation is not complete and there is not sufficient information for a solution. It would make no sense for me to guess what a + b equals since, in that case, I may as well start posting my own questions and answering them!
2y equals -4x - 5?
This is an equation of a straight line. A solution for two unknowns requires two (independent) equations; there is only one here. Every point that is on that line is a solution to the equation. So you can let x be any real number and find a corresponding y. This ordered pair (x,y) will be a solution to the equation as well as a point on the graph of the line.
What is the solution to 4 equals 2b plus b squared?
To find the solution to this equation, you need to rearrange the terms and solve for the variable. 4 = 2b + b^2 can be rewritten as b^2 + 2b - 4 = 0. You can then solve this quadratic equation by factoring, completing the square, or using the quadratic formula.
Can you solve x plus 2y equals 2?
No. There is not enough information in the equation x + 2y = 2, by itself, to solve it. There are an infinite number of solutions. A second equation, or information to allow a second equation to be derived, must be given to find a solution.
How do you do an equation like -234 equals 3x?
-234 = 3x, properly written 3x = -234, is no different from any other algebraic equation even though the result is a negative number. Divide both sides by 3 to find the solution. 3x = -234 x = -78 (- 234/3 = - 78)
