@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.

- anonymous

thank you! one last thing can you tell me how to solve part B?

- anonymous

@kash_thesmartguy

- anonymous

gj @MrSkipped8thGrade

- anonymous

thank you!!! @MrSkipped8thGrade & no just to justify your answer mathematically

- anonymous

which you did

- anonymous

20% of 30 is 6 (for neighborhood A) so every year adds 6 houses

- anonymous

wait i messed up a few times in there let me backtrack

- anonymous

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

- anonymous

ok

- anonymous

for part B
neighborhood A has 60 as well as neighborhood B (after 5 years)

- anonymous

is that it?

- anonymous

for part A
neighborhood A
f(x)=30+6x
neighborhood B
f(x)=45+3x
where x = number of years

- anonymous

the first one wouldn't be f(x) = 30 x 0.2x ?

- anonymous

plug in the formula for after 3 years

- anonymous

ok i did I'm going to submit now

- anonymous

f(x) = 30 x 0.2(3)
f(x) = 30 x .6
f(x) = 18
this shows a decrease in houses. obviously not it.

thanks
