Answer: $34

Step-by-step explanation:

39 x 0.2 = 7.80, the discount

39 - 7.80 = 31.20

31.20 x 0.09 = 2.80, the tax

31.20 + 2.80 = 34

Determine any data values are missing from the table assuming that the data represents a linear function.
IgorC [24]

Answer:

Missing x:0

Missing y:1

Hence, option b is correct.

Step-by-step explanation:

Given the table

x                          y

-9                         3

-6                          2

-3                          missing

missing                  0

As we know that the linear function has a constant common difference between the x values and y values.

From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by -3.

i.e. -9-(-6)=-3

-6-(-3)=-3

So the missing x value will be:

-3-(x)=-3

-3-(0)=-3

Therefore, the missing x value wil be: 0

From the table, it is clear that the x values have the same common difference, and the consecutive x values are separated by 1.

i.e.

3-2=1

2-y=1

y=1

Therefore, the missing y-value will be 1.

Therefore,

Missing x:0

Missing y:1

Hence, option b is correct.
