First notice that you need to move 2 units to the left from the origin in order to be exactly above the point for the city park. Because the x-coordinate is 0, you do not need to move to the right or to the left from the origin. The x−axis is the horizontal axis in the coordinate plane, commonly representing the value of the input or independent variable.

The order of operations specifies the order in which to perform each of multiple operations in an expression or equation. The order of operations is: P - parentheses, E - exponents, M/D - multiplication and division in order from left to right, A/S - addition and subtraction in order from left to right.

The area of a triangle is A=(1/2)bh, where b is the base of the triangle and h is the height. The area of a trapezoid is 72 ft 2 , the height is 8 ft and b 1 is 6, what is the length of the other base? For questions 16-17, use the equation for the surface area of a cylinder, SA=2πr 2 +2πrh, where r is the radius and h is the height.

Now, treat the fraction bar as a grouping symbol and complete the operations above and below the bar independently until the numerator and denominator are simplified. There, we have a fraction so we have to simplify the fraction first, simplifying the numerator and then the denominator before dividing.

When working with an equation involving a single variable, you are looking for the number that gives a true statement when you replace the variable by the number. The number that gives the true statement is said to “satisfy” the equation and is called the solution or root of the equation.
