5/9-2/12=?
9x8=72
5x8=40
12x6=72
2x6=12
40/72 - 12/72 = 28/72
28/4=7
72/4=18
28/72=7/18
Answer:
(A) The number of bacteria is originally 300 and increases by 30% every hour
Step-by-step explanation:
I am assuming the function should actually read:

(i.e., there should be a "t" in the exponent. if this is not the case please disregard my answer).
According to the above exponential function, the initial amount 300 grows as (1+0.3)*300=300+0.3*300. In other words it increases by 30% every hour (t).
Your answer choice (A) is likely a candidate, except I am missing "every hour" at the end (again, am assuming this was omitted by mistake)
Answer:
So the solution would be (1,-2). Remember you can always validate that the solution is correct by plugging it into both equations. But this is the same as the first equation, y=3x-5. Since they are the SAME line they will have infinite solutions.
Step-by-step explanation:
3/6 canister or one half canister because 2 loaves is 1/3 and 1 loaf is 1/6 so (1/6 x 3)=3/6
