The rule is "a number subtract 6"

• 23

• 22

• 21

• 26

Find the rule the pattern is using:

8,16,32,64

• Add 16

• Multiply 2

• Add 8

Look at the table below. Write an equation to match the pattern between m, minutes and bubbles blown, b.

• b = 12(m)

• b= m +12

• b = m ÷ 12

• none of these

Write an equation that represents the relationship between the variables in the table.

• t=10d

• t=d-9

• t=10-d

• d=t+10

Nancy can type 50 words per minute. Look at the table below to write an equation that matches the data.

• m=50 + w

• w= 50m

• w= 50 + m

• m= 50 - w

Name the INDEPENDENT variable from the table below.

• words

• minutes

Name the DEPENDENT variable from the table below.

• minutes

• bubbles

How does the input relate to the output?

• The output is the input multiplied by 3.

• The output is the input plus 3.

• The output is the input minus 3.

• The output and input are not related.
