Answer:
D.
Step-by-step explanation:
All other equations have x or y to the power of one so they are linear. D. has x or y to the power of two, so it's not linear. Quadratics and any variable to the power of 2 and above is not linear (numbers on their own are also always linear, so ignore any powers on them)
Answer:
Question 2:
If the size of bacteria is 2000 initially and doubles after every half hour
It means in the 1st 30 min its size is 2000
And in 60 min its
30min=2000
60min=?
60×2000=120000
120000÷30
=4000
And in 9hrs
1hr=60min
9hrs=?
60×9=540min
30min=2000
540min=?
2000×540
=1080000÷30
=360000
Literally just add it all up.
312.8+177.2+209=699 miles
