Distribute all the negatives: 7a-9c+12a+33c+21a-10c
simplify:
40a+14c

It's a pretty straightforward subtraction problem. As with any decimal addition or subtraction, you line up the decimal points and extend any numbers with zeros to make the number of decimal places match.
Answer:
y= 8000x + 2000
Step-by-step explanation:
to find the formula we can use the points given in the question:
the slope:
to get the slope we can take the 2 points, (0,2000) and (2,18000) where x values are time and y values are bacteria
now using slope-intercept form we can get
which gives a slope of 8000 meaning for each hour there are 8000 new bacteria
intercept:
since we start with 2000 bacteria we know this is the y intercept so when x is 0
formula:
y=8000x + 2000
Answer:
The answer is C
Step-by-step explanation:
I pick that answer because you have divide
