Answer:
170.3 miles per hour
Step-by-step explanation:
Javon won Indianapolis 500 race in 2011 with an average speed of 170.265 miles per hour. What was his average speed to the nearest tenth of a mile per hour?
From the above question, we are asked to approximate to the nearest tenth of a mile.
The number that falls under the tenth of a mile, is the number that is immediately after the decimal.
Hence, for:
170.265 miles per hour:
2 is the number in the tenth place, the number after 2 is 6, it is a number that is higher than 5. So we add 1 to 2
Therefore,
170.265 miles per hour to the nearest tenth of a mile = 170.3 miles per hour.

Point c.
You can graph the two points in a calculator to find out the answer OR you can identify the lines using the y-intercept aka b in the y=mx+b format.
Y=x - 3 has a y-intercept of -3, so look for the line where it goes through -3 on the y axis. (do the same for the other except when the y-intercept is 1)
From this, you can identify the lines and just find where they intersect.
Answer: 18
Step-by-step explanation: 3 + 10 = 13. 3 + 2 = 5. 13 + 5 = 18
