Answer:Lesson Guide

Have students read the prompt, examine the ratio table, and graph the points.

Ask:

Why do you think the table is called a ratio table?

How can you complete the table?

How is the information in the ratio table represented in the graph?

How can you plot the points on the graph?

Use any disagreement to prompt a discussion.

Mathematics

The start of the lesson focuses students’ attention on the connection between the pairs of values in the table and the points on the graph and asks them to add information to each representation. Incorrect attempts at adding values or points to the representations are especially productive at this point in the unit; use them to surface misconceptions about the connections between tables and graphs and to provide opportunities for revising student thinking.

Note: You may need to point out that the packages are all the same size if students raise the question.

Ratio Tables and Graphs

Ms. Lopez sells muffins at her bakery. She sells them in packages.

She uses a ratio table to determine the number of packages she will need for different numbers of muffins. The table she uses shows equivalent ratios of number of packages to number of muffins.

She can also use a graph to show this information.

Complete the ratio table with your class.

Using the graph on the handout, graph paper, or a graphing tool, plot all the points in the ratio table on a graph.

Examine the graph. How is the information in the ratio table represented in the graph?

HANDOUT: Ratio Tables and Graphs

Muffins 5 10 15 25 100

$g(x) = 4x - 5$

let's solve for f(x) × g(x) :

$( {x}^{3} + 2x {}^{2} + 3x + 1)(4x - 5)$

$4x {}^{4} - 5 {x}^{3} + 8 {x}^{3 } - 10 {x}^{2} + 12 {x}^{2} - 15x + 4x - 5$

Find the area of the region bounded by the line y=3x-6 and line y=-2x+8.

Vikentia [17]

Answer:

A = 12/5 units

Step-by-step explanation:

USING ALGEBRA:

We can find the intersection point between these two lines;

y = 3x - 6

y = -2x + 8

Set these two equations equal to each other.

3x - 6 = -2x + 8

Add 2x to both sides of the equation.

5x - 6 = 8

Add 6 to both sides of the equation.

5x = 14

Divide both sides of the equation by 5.

x = 14/5

Find the y-value where these points intersect by plugging this x-value back into either equation.

y = 3(14/5) - 6

Multiply and simplify.

y = 42/5 - 6

Multiply 6 by (5/5) to get common denominators.

y = 42/5 - 30/5

Subtract and simplify.

y = 12/5

These two lines intersect at the point 12/5. This is the height of the triangle formed by these two lines and the x-axis.

Now let's find the roots of these equations (where they touch the x-axis) so we can determine the base of the triangle.

Set both equations equal to 0.

(I) 0 = 3x - 6

Add 6 both sides of the equation.

6 = 3x

Divide both sides of the equation by 3.

x = 2

Set the second equation equal to 0.

(II) 0 = -2x + 8

Add 2x to both sides of the equation.

2x = 8

Divide both sides of the equation by 2.

x = 4

The base of the triangle is from (2,0) to (4,0), making it a length of 2 units.

The height of the triangle is 12/5 units.

Formula for the Area of a Triangle:

A = 1/2bh

Substitute 2 for b and 14/5 for h.

A = (1/2) · (2) · (12/5)

Multiply and simplify.

A = 12/5

The area of the region bounded by the lines y = 3x - 6 and y = -2x + 8 between the x-axis is 12/5 units.

the big wheel could have a 52 inch diameter and the small wheel could have an 18 inch diameter.What is the circumference of the

BlackZzzverrR [31]

Before we begin, let's cross out "the small wheel could have an 18 inch diameter". This is useless information and should be disregarded to avoid confusion. Lots of questions include extraneous information to make you second guess yourself, so it is important to be aware of what the question is asking you and what you need in order to answer it.

The formula for circumference is $\pi$ x diameter. With this formula, we can substitute the value of the diameter, 52, into the equation.

Circumference = 3.14 x 52
Circumference = 163.28

Final Answer: the circumference of the big wheel is 163.28 inches
