Write down the triangle's original coordinatesPlot the original coordinates on a graph. Connect the points to form a triangle. Label the points of the triangle as A, B and C. On a separate sheet of paper, write down the x and y coordinates of points A, B and C as (x, y).Flip the coordinates, and make the x negativeOn your list of coordinates, write down the flipped coordinates of points A, B and C as (y, x). Make each x coordinate of the flipped coordinates negative by placing the negative symbol next to it.Plot the flipped coordinatesUse a different-colored pen or pencil than the one tha..

Set the proportions as fractionsWrite both of the ratios as fractions in the equation. Convert 2:x to 2/x and then 3:9 to 3/9. If you want, 3/9 can be reduced to 1/3, since both the numerator and denominator divide equally by three. Cross-multiply the ratiosUsing 2/x = 3/9, cross-multiply in an "X" pattern across the equals sign to form a linear equation. In this case, take 9x2 and 3x. The equation becomes 3x = 18. The reduced fraction of 1/3 yields the equation x = 6 when you multiply 1x and 3x2.Solve the equationSolve for x in the linear equation by dividing both sides by three. The result i..

The top number of a fraction is the numerator, and the bottom number is the denominator. If the denominator is equal to 1, the value of the fraction is equal to the numerator. When the numerator's value is higher than the value of the denominator, the fraction is referred to as an improper fraction. Any fraction equal to 125 is an improper fraction. Among other fractions equal to 125 are 250/2, 375/3, 500/4 and 1250/10.

Similar figures make sense when thought of as resizing. If one takes a shape and simply uses a tool to enlarge it, then the new bigger shape and the original smaller shape are similar. Each of the shapes' corresponding sides are proportional to the other. On the other hand, if two figures or shapes are the same size then they are congruent.

Even though inverse operations are used to solve the equation, the inequality symbol remains the same. Once the equation has been solved, only the inequality symbol and remaining value should be left. The value will be noted as either less than or greater than N. The inequality might read, for instance, as N is less than or equal to (the value of) 5. That means the solutions created by the inequality include the value 5 and all numbers less than 5. On a graph, that solution is drawn by creating a number line, such as from zero to ten, then highlighting all numbers up to and including five, sta..

Math is a life skill needed by everyone to make even simple choices in regard to insurance rate, investment options and looking at stock market trends and data.Math is necessary even in sports and for playing board games like chess where one has to make strategic moves. In sports, some uses of math include knowing about statistics, probability and geometry. For example, in bowling, players need to figure out the best angle to throw a ball for a strike.

Other important arithmetic and geometric formulas include the formulas for finding the partial sums of arithmetic and geometric sequences. Given a sequence of figures, the student can apply either a geometric or arithmetic formula to find a specific missing term in the series or the sum of the series. The first step is to determine whether the sequence is a geometric or arithmetic sequence.\nFor an arithmetic sequence, the student can easily determine the common difference by subtracting the successive terms in the sequence. However, for a geometric sequence, the student must pick a pair of nu..
How do you find the point-slope form of an equation?

Plug in the given values to the point-slope formFor example, if given the point (3, 5) and a line with a slope of 2, plug in the values into the x1 and y1 terms of the equation. Doing this gives you y - 5 = 2(x - 3). Simplify the equation on the right side by multiplyingMultiplying the 2 on the right side by both x and -3 simplifies the equation into y - 5 = 2x - 6.Cancel out the term on the leftAdd 5 to both sides of the equation. This isolates y and changes the term on the right to 2x -1. Thus, the equation for the line in slope-intercept form is y = 2x - 1. The line crosses the y-axis at (0..

An example using the less than sign is 5 < 10. Several signs show the relationship between expressions in a mathematical statement. The equal sign is =, and the "not equal sign" is the same as an equal sign with a left-slanting line through it. The greater than sign is >, and the greater than or equal to sign is > with a horizontal line beneath it.
Is zero a perfect square?

A perfect square is the product of an integer multiplied by itself. For example, three times three equals nine. Nine is therefore a perfect square. Zero times zero equals zero, suggesting that zero is a perfect square. However, the historical definition requires that objects can be arranged in a square. Nine objects can be arranged in a 3x3 square. Zero objects cannot be arranged in a square.
