The way you round is if it is below 5 you round down and if it is above 5 you round up so in the case of 750 it would go to 800 where if it was 749 it would go to 700

5) 43.97mph a) $492 b) $401.20
Step-by-step explanation:
Answer:
8. C 9. B
Step-by-step explanation:
8. (-15)/3 = -5
-5 + 17 = 12
9. 14-3 = 11
2 x 11 = 22
Answer:
-5
Step-by-step explanation:
12+18y-7y+35=-8
11y+47=-8
11y=-55
y=-5
Answer: Choice A) y = cx
The 'c' is the constant of variation
For example, if c = 2, then y = 2x is a direct variation. Whatever x is, we double it to get y. As x increases, so does y. As x decreases, then so does y. Both x and y increase/decrease together.
Direct variation equations always go through the origin, and they are always linear. The 'c' plays the role of the slope. You can think of y = cx as y = mx+b where b = 0 in this case and c = m.
