Chapter Review Pg. 360 Questions: 7 and 8.

                                                                                                                          

    B) Yes, because the points on the graph are straight. 

    C) Yes its possible. Klaus can only work for part of the hour. 

 Question 8

a) The graph shows how many cars were washed at the grade 8 car wash. 

b) The points are showed as a straight line meaning that its a linear relation. 

c) The cost for 1 car wash is $10.

d) table of values. 

1   10 

2   20 

3   30

4   40

5   50 

9.3 Practice Test Page 362. Questions: 2 and 3

    

  

The correct answer would be letter "B". If we used that for base 1,2 and 3 it would work. 

Ex: 3 (1) = 3 

       3 (2) = 6

       3 (3) = 9

The graph relates to the letter C on the table of values. It's the answer because the numbers on the table of values are plotted on the graph.

7.) klaus receive $9 every hour. it can be represented as H and $ where (H) is hour and ($) is money.

A.) Table of values

 

B.) Yes the graph represent a linear relation because the values are in a pattern (Over one up nine)

C.) Yes because you can have half an hour and you can take the half of the money

8.) A $10 car wash can be represent as C and $ where (C) is cars and ($) is money

A.) Each Car you wash will be $10

B.) the pattern is over one up ten

C.) Each car wash cost $10
D.)Table of Value

 

E.) c= x10
      c=(15)10

Chapter 9 review page 360-361.

7.A) Here is my table of values.

B.) Does the graph represent a linear relation? explain.

answer: Yes, the graph represents a linear relation because the points on the graph lay on a straight line.

C.) Is it possible to have other points between the ones on this graph? Explain.

Answer : 

8.) Describe what the graph is about.

Answer: The graph shows the amount of money earned at a grade 8 car wash based on the number of the car washed.

B.) Describe patterns on the graph.

Answer: For every car that is washed $10 is collected. the pattern on this graph is 10  

C.) what is the cost of one car wash? 

Answer: the cost of one car wash is $10.

D.) Table of values.

E.) If 15 cars are washed, what is the income for the grade 8? 

Answer: 15 x 10 = 150, $150 is the income of the grade 8.

9.) Describe the patterns on the graph.

Answer: The point lie in a straight line. the pattern is +2.

B.) My table of values.

C.) Y=  when X is 2 

D,) Y= 17 when X is 5

Graphing: Textbook Page 340

A) 

 

B) The pattern is that ever 100 quantity, it would cost you 75 dollars, so you just keep adding 75.

 

C) half of 75 is 50, so If the quantity is 350 it would be 225, which is 225 plus the 50 which is 37.5 so that should add up to 242.5

 

D)242.5

E) Its the same thing

 

A) 

B) For every 2 boxes of almonds you make a 1 dollar profit. Divide

the boxes of almonds by two then you will get the profit. In the boxes of almonds you add by two and profit you add by 1.

C) The School makes a 1 dollar profit.

 

D)Its basicly the same thing as number C, but turned around.

 

 

 

A) It means that tome can type 80 words in 2 minutes.
B) 40 words per minute.
C) Yes because if you connect the dots, it will be a line.
D) NO because your typing speed can be different each time.
