For the marigolds
M = 150(0.85)^x where x is the number of months
For sunflowers
S = 125 - 8x where x = number of months
Part B
after 3 months there are 150(0.85)^3 = 92 marigolds
after 3 moths there are 123 - 8*3 = 99 sunflowers
Part C
There are the same number of plants when the 2 functions are equal:-
So we have 150(0.85)^x = 125 - 8x
solving this for x is not straight forward . it could be done by drawing 2 graphs and seeing where they intersect.
They come close to being equal after 2 months and after 14 months

Answer:
Step-by-step explanation:
If you want to find the equation of line with a given a slope of which goes through the point (-4,5), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
where is the slope, and is the given point
So lets use the Point-Slope Formula to find the equation of the line
Plug in , , and (these values are given)
Distribute
Multiply and to get
Add -1 to both sides to isolate y
Combine like terms and to get the answer
So the equation of the line with a slope of which goes through the point (-4,5) is:
which is now in y=mx = b form where the slope is m=-4/5 and the y-intercept is b=1
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
We will use law of exponents :
So, the simplified form is
Hence, First option is correct.

Answer:
9.42
Step-by-step explanation:
It is 9.42 because if you multiply the radius by 2 to get diameter you multiply the diameter by 3.14 to get your final answer which is 9.42 :)
