Answer:
C. green is not a function, red is a function
Step-by-step explanation:
A curve does not describe a functional relationship if a vertical line crosses it in more than one place. Clearly the y-axis crosses the green curve in 2 places, so it is NOT a function.
There is a very steep section at x=10 on the red curve. It we assume it is simply "very steep" and not "vertical", then the red curve IS a function. If you assume that short section is vertical, then the red curve is not a function, either. My choice is to go with "very steep," not "vertical."
My conclusion is that green is not a function; red is a function.
Answer:
S = 935 when t ≤ 7
S = (180t - 325) when t > 7
Step-by-step explanation:
John's weekly salary = $375 + commission on number of cars he sell
Commission for the first seven cars sold = $80 per car
Commission above 7 cars = $180 per car
If John sells t cars each week then commission earned by John
= 80×7 + 180(t - 7)
So the salary for week = 375 + commission
S = 375 + 560 + 180(t - 7)
S = 935 + 180(t - 7)
S = 935 when t ≤ 7
(180t - 325) when t > 7
Answer:
3/4, and 6/8
Step-by-step explanation:
3/4 = 9/12 simplfied
6/8 = 3/4 times two
Answer:
0.555km p/h
shown as 555m p/h
Step-by-step explanation:
First we convert km to meters
6k = 6000m
Time = distance / rate.
20/6 = 3.33333333 = 3hr + ( 0.33 x 60 = 19.8) - 3.20hr
then 3.33 / 6 = 0.555 km = 555 meters p/h
