How do i know if an equation has one solution
WebWhen two equations have the same slope, they will have either no solution or infinite solutions. By putting both equations into the form , we get: and. With the equations in this form, we can see that they have the same slope, but different y-intercepts. Therefore, there is no solution to this system. WebSolution: Given equations are y = -3x + 9 y = -3x – 7 Here (a 1 /a 2) = (b 1 /b 2) ≠ (c 1 /c 2 ). So this system of equations has no solution. Another method: Without graphing them, we can see that both have the same slope -3 which means lines are parallel. Hence the system of equations has no solution. So option (B) is the answer. Example 2:

WebNov 24, 2014 · A quadratic equation that has only one rational solution will be one where: The discriminant equates to 0. (the expression underneath the square root sign will equal 0) This means that the curve will not cross the x-axis in two places. The solution is a rational one Share Cite Follow answered Nov 19, 2014 at 6:36 Aran Mulholland 201 1 4 9 WebOct 17, 2024 · Exercise 8.1.1. Verify that y = 2e3x − 2x − 2 is a solution to the differential equation y′ − 3y = 6x + 4. Hint. It is convenient to define characteristics of differential equations that make it easier to talk about them and categorize them. The most basic characteristic of a differential equation is its order.
WebCombining like terms yields. x - 2 = 10. Adding 2 to each member yields. x-2+2 =10+2. x = 12. To solve an equation, we use the addition-subtraction property to transform a given equation to an equivalent equation of the form x = a, from which we can find the solution by inspection. Example 3 Solve 2x + 1 = x - 2. WebYes: by showing that the system is equivalent to one in which the equation 0 = 3 must hold, you have shown the original system has no solutions. By definition, a system of linear equation is said to be "consistent" if and only if it has at least one solution; and it is "inconsistent" if and only if it has no solutions.
WebBe careful: for a quadratic equation to have one solution, its graph must touch the x axis exactly once. If the graph touches the x axis twice, then it has two real solutions. If the graph does not touch the x axis at all, then it has two complex solutions (and no real solutions). Look At The Coefficients WebTo find out if a solution has one solution, no solution or infinite solutions with the graphical method, plot the equations on a graph and see where they intersect. If they intersect at …
