The two-way table shows some survey results from when 100 Georgia residents were asked whether they were born in Georgia.

There are values missing from the two-way table. You will need to determine the missing values from the two-way table.

How many of the males surveyed were not born in Georgia?

• 16

• 18

• 29

• 34

The two-way table shows some survey results from when 100 Georgia residents were asked whether they were born in Georgia.

There are values missing from the two-way table. You will need to determine the missing values from the two-way table.

Select TWO statements that are true about the data.

• There were more males born in Georgia than there were females born in Georgia.

• More than half of all residents surveyed were born in Georgia

• More males were born in Georgia than were not born in Georgia.

• More females were not born in Georgia than were born in Georgia.

• There were more females not born in Georgia than there were males not born in Georgia.

• 
• 
• 

Which system of equations has exactly one solution?

• 5x – y = –3

  5x – y = –2

• 8x – 3y = –12

  x – 3y = 9

• 3x – y = 4

  9x – 3y = 12

• 2x – y = 3

  2x – y = –4

A system of equation is shown.

y = 3x + 2

y = x - 2

Graph the system of equation to show its solution.
