Linear Equations App Quiz! Trivia Questions

The correct answer is "ab". The "ab" app is likely a mathematical application that can be used to solve equations. In this case, the equation for a line with a gradient of 5 and a y-intercept of 7 can be solved using the "ab" app.

The given problem involves a difference equation, which is a type of recursive equation. The term "recursion" refers to the process of solving a problem by breaking it down into smaller, similar subproblems. In this case, the 5th term of the difference equation can be found by using the given values of a, r, and d. Therefore, the recursion app would be the most appropriate to use for solving this problem.

The "makesubject" app allows you to rearrange the equation to make "x" the subject. In this case, you can rearrange the equation "y=2x-4" to solve for "x" by adding 4 to both sides and then dividing by 2. This will give you the value of "x".

The correct answer is "intercepts". The question asks for the coordinates of the point where the two lines cross. In order to find this point, we need to determine the intercepts of each line. The first line has a y-intercept of 4 and an x-intercept of 2, while the second line has an x-intercept of 4 and a y-intercept of 2. By finding the intercepts of each line, we can determine the coordinates of the point where they cross.

The correct answer is "twopoints" because the given problem involves finding the equation for a line given two points. The "twopoints" function in the app is specifically designed to solve this type of problem. It takes the coordinates of two points and calculates the equation for the line passing through those points.

Recursion is the correct answer because it allows for the repeated calculation of a value based on a previous value. In this problem, the amount of money accumulated each year is dependent on the previous year's amount, as well as the interest earned and the additional deposit. By using recursion, the calculation can be done iteratively for each year, resulting in the total amount of money accumulated after 5 years.

The correct answer is "makesubject". In order to solve the equation 26=12y - 2, we need to isolate the variable y. The "makesubject" app allows us to rearrange the equation so that the variable y is on one side of the equation and the constant terms are on the other side. This app helps us simplify and solve the equation by making the variable the subject of the equation.

The app "expressevaluate" can be used to find the value of the expression 3x-5y. By plugging in the given values of x and y (x=5 and y=-2) into the expression, we can evaluate it to get the result. In this case, substituting x=5 and y=-2 into 3x-5y gives us 3(5)-5(-2), which simplifies to 15+10, resulting in a final value of 25.

The correct answer is "equationcompare". This app is specifically designed to compare equations and determine if they are the same. In this case, the app would analyze the given equations y=2x+4 and 2y-8=4x to determine if they are equivalent or not. It would compare the coefficients and constants on both sides of the equations to make this determination.

To check if your answer is the same as one of the given options, you can use the "equationcompare" function. This function allows you to compare your equation (y=2x+4) with each of the multiple-choice answers. By inputting your equation and the options into the "equationcompare" function, you can determine if any of the options match your answer.

To find the value for the expression 2x-y, substitute the given values of x and y into the expression. In this case, x is 5 and y is -2. So, substitute these values into the expression: 2(5)-(-2). Simplify the expression to get the final value.

The correct answer is "simequations" because it is an app specifically designed to solve systems of equations with multiple unknowns. It can help find the values of each unknown variable by using various methods such as substitution, elimination, or matrix operations. This app is likely to provide the most efficient and accurate solution to the given problem.

The correct answer is "intercepts". The question asks for the equation of a line that crosses the y-axis at 3 and the x-axis at 12. The intercepts of a line are the points where it crosses the x-axis and the y-axis. Therefore, using the intercepts method would be the most appropriate way to solve this problem and find the equation of the line.

The correct answer is "twopoints". To find the equation for a line on a graph, you need to know the coordinates of two points on the line. The "twopoints" app is likely designed to help you input the coordinates of two points and then calculate the equation of the line passing through those points.
