Access full lesson containing this video at: www.yourteacher.com Students learn to graph a given linear equation using a chart. For example, to graph the equation y = x - 4, pick three values for x, such as -1, 0, and 1, and substitute these values into the equation to find the corresponding values of y. Next, plot the resulting points on a coordinate system and graph the line that passes through them. To graph the equation 3x + 5y = 5, first solve for y, to get y = -3/5x + 1. Then set up a ...

And since pi = 3.14, 4000 pi cubic feet can also be written as 4000 times 3.14, or 12560 cubic feet. Students also learn that the formula for the volume of a sphere ...

Access full lesson containing this video at: www.yourteacher.com Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2. Note that the prime factorization of a prime number, such as 23, is the number itself.

For example, to write 82% as a decimal, think of 82% as 82/100, and remember that dividing by 100 moves the decimal point two places to the left, to get 0.82. So 82% can be written as the decimal 0.82. Since a percent can be written as a decimal by moving the decimal point two places to the left, a decimal can be written as a percent by moving the decimal ...
Access full lesson containing this video at: www.yourteacher.com Students learn to write percents as fractions and fractions as percents. For example, to write 6% as a fraction, remember that percent means "out of 100", so 6% can be written as the fraction 6/100, which reduces to 3/50. So 6% can be written as the fraction 3/50. To write 7/10 as a percent, set up the proportion 7/10 = x/100, then use cross products to get (7)(100) = (10)(x), or 700 = 10x, and dividing both sides by 10, 70 = x ...

And since pi = 3.14, 25 pi square inches can also be written as 25 times 3.14, or 78.5 square inches. Note that the radius of a given circle is half the diameter of the circle. So to find the area of a circle with a given diameter, first find ...

Note that "what" means "x", "24%" means "24/100", "is" means "equals", "of" means "times", and "175" means "175". So this word problem can be translated into the equation x = 24/100 times 175.

For example, to convert the fraction 7/10 to a decimal, first read the fraction as "7 tenths". Next, since the tenths place is one place to the right of the decimal point, 7 tenths can be written as the decimal 0.7. To convert 11/20 to a decimal, first find a fraction that is equivalent to 11/20 that has a denominator of 100, so multiply both the numerator and denominator by 5 ...

Next, add across the numerators and keep the ...
Access full lesson containing this video at: www.yourteacher.com Students learn to solve problems that combine the exponent rules covered in this chapter. For example, students may use the power rule, the product rule, and the quotient rule all in the same problem. Students also learn that when a fraction is taken to a power, both the numerator and denominator of the fraction are taken to that power.
Students learn to divide fractions by first changing the division sign to multiplication and flipping the second fraction. For example, to simplify 7/12 divided by 7/9, first change the division sign to multiplication and flip the second fraction, to get 7/12 x 9/7. Next, multiply the fractions by first cross-canceling, then multiplying across the numerators and across the denominators. **See more education videos by TeacherTube Member yourteacher at www.TeacherTube.com***
