Part A: Write functions to represent the number of homes in Neighborhood A and Neighborhood B throughout the years. (4 points)
Part B: How many homes does Neighborhood A have after 5 years? How many does Neighborhood B have after the same number of years? (2 points)
Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points)
@Kash_TheSmartGuy can you help please?
Part A: \[f(x)=30*0.2x\]and\[f(x)=45+3x\] Part B: \[f(x)=30+0.2(5)\]\[f(x)=45+3(5)\]For Part B solve them. Part C: No idea. Ask someone else.
thank you! one last thing can you tell me how to solve part B?
ill try part C
wow you're very helpful! haha
You get it, now? Just use formulas
@Kash_TheSmartGuy yes because of mrskipped8thgrade
thank you!!! @MrSkipped8thGrade & no just to justify your answer mathematically
which you did
20% of 30 is 6 (for neighborhood A) so every year adds 6 houses
wait i messed up a few times in there let me backtrack
1 A=36 B=48 2 A=42 B=51 3 A=48 B=54 4 A=54 B=57 5 A=60 B=60 Answer is actually 5 years exacly
for part B neighborhood A has 60 as well as neighborhood B (after 5 years)
is that it?
for part A neighborhood A f(x)=30+6x neighborhood B f(x)=45+3x where x = number of years
the first one wouldn't be f(x) = 30 x 0.2x ?
plug in the formula for after 3 years
ok i did I'm going to submit now
f(x) = 30 x 0.2(3) f(x) = 30 x .6 f(x) = 18 this shows a decrease in houses. obviously not it.
no problem, anytime. :)
did you get it answered on time? or are you turning an assignment in late? or did you say you only had twenty mins to attract answers?
i turned it in late.
that sucks oh well
let me know if you ever have other questions and I will try to help you. :)
yeah but you were really helpful because i was having a lot of trouble with that lesson
