(D)
The high school's enrollment in 2017 is 2500
Step-by-step explanation:
Let's assume time starts since 2009
so, In 2009 , t=0
P=900
In 2012,
t=2012-2009=3
P=1500
(A)
So, we have points as


(B)
we can use slope formula

we can plug values


we know that
slope is rate of change of P with respect to time
so, slope means increase in population is 200 per year
(C)
we can use point slope form of line





(D)
In 2017 ,
t=2017-2009=8
we can plug t=8
and we get


The high school's enrollment in 2017 is 2500
Answer:
37.5
Step-by-step explanation:
Selling price= 750
Sales tax= 5%
5/100 because we are looking for 5% ot of 100%
750*0.05
Distance = 13.243 * 22.07= 292.27miles
Answer:
2/3
Step-by-step explanation:
you can set it up as x/y because it varies directly
so when y=6 x=72
72/6 = 12
so x will always be 12 times greater than y
x=12y
so if x=8
8=12y
y=8/12
y=2/3
