Answer:

C. a number whose square root is a whole number

Step-by-step explanation:

A number whose square root is a terminating decimal is not a perfect square.

A negative whole number cannot be a perfect square.

A number times itself is squared, the number itself is not a perfect square.

The correct answer is option C, a number whose square root is a whole number. For example: 4 is a perfect square.

\sqrt{4} =2

The square root of a perfect square is always a whole number.

I need to solve the three representations (the table, rule/equation, and the graph)
Hitman42 [59]
Figure #5 shows 5 squares which I would assume means (5, 5)
In the table you have the point (3, 7)
From this you can find the slope: (7 - 5)/(3 - 5) = -1 
Completions of table:
x     y
0   10
1     9
2     8
3     7
4     6
5     5
6     4

Rule/Equation:
y = -x + 10

Graph: Plot the ordered pairs from the table

How many people own a SUV?<br> A. 4<br> B. 42<br> C. 420<br> D. 4,200
MaRussiya [10]
For this, no math is even needed! The question says 1,000 people were interviewed. 42% percent of that 1,000 owns an SUV. If it's a percent, it is 42/100, right? Now we have to make that 42/100 out of 1000. We add a zero to the 100 on the bottom (42/1000). We do the same thing on the top. Add a zero! 420. 

SECOND POSSIBLE SOLUTION
Solve this with logic! 42% is nearly 50%. Half of 1,000 is 500. What is closest to 500? 420! This solution is even easier.

Hope this helps you!
