Answer: 5 games
Step-by-step explanation: They need to win half their games for a .500 record and half or 30 is 15. They already won 10 so they need to win 15- 10 = 5 more games to have a .500 record.
It's B.) The student’s answer is not reasonable. Estimation: 170 + 90 = 260
ANSWER
The rule is given by the relation,

EXPLANATION
We need to check and see if there is a constant difference between the y-values.

We can see that, there is a constant difference of 2.
This means that the table represents a linear relationship.
Let the rule be of the form,

Then the points in the table should satisfy the above rule.
So let us plug in

This implies that,



Our rule now becomes,

We again plug in another point say, (-1,-1) in to equation (1) to get,

we solve for m now to obtain,



We now substitute back in to equation (1) to get
58,000,000 km.
5.8 × 10⁷ Km
0.0025 cm
2.5 × 10⁻³ cm
5.8 × 10⁷ Km > 2.5 × 10⁻⁸
5.5+-3.3 is the same as 5.5-3.3 so
5.5
-3.3
——
2.2
5-3 = 2
5-3 = 2
