Answer:
<em>Set the function equal to 0</em>
Step-by-step explanation:
<u>Standard Form of the Quadratic Equation</u>
The form

is called the standard form of a quadratic equation. It can be clearly identified the terms of a second-degree polynomial equated to 0.
The equation is given in the form:

And we need to operate the expression to make it look like a standard form. The first logical step should be to set the function equal to 0 and then start to operate the resulting expression. It can be done by subtracting 8 on both sides of the equation:

Answer: Set the function equal to 0
Answer:
The slope for the line is 2
Answer:
5 x 8 * 3 = ?
Step-by-step explanation:
Answer:
Rachel's conclusion is valid. The ratios for green beans to total students for the survey and the school form a proportion.
Step-by-step explanation:
Solve using proportions. The format should be "Green beans" on the top, and "Total students" on the bottom.

Simplify the first numerator
Find the <u>common ratio</u>
The common ratio is the number you multiply by to get from the top left to top right. It's the same number the you can multiply the bottom left number by to get the bottom right.
<u>Divide the right side by the left side to find the ratio.</u>
Top: ratio = 240/10 = 24
Bottom: ratio = 600/25 = 24
Since the ratios are <u>the same</u>, they are <u>common</u>.
Therefore the proportion is correct, and Rachel's conclusion is valid.
