In 2009, a town's population was about 9,000 residents. In 2014, the population was about 12,500 residents. Which linear model represents the town's population, p, as a function of t, the time in years after 2007
Answer:
Population function (Based on 2007) = 7,600 + 700n
Step-by-step explanation:
Given:
Population in 2009 = 9,000
Population in 2014 = 12,500
Computation:
Increase in population per year = [12,500 - 9,000] / 5
Increase in population per year = 700
Population in 2007 = 9,000 - [2 x 700]
Population in 2007 = 7,600
Population function (Based on 2007) = 7,600 + 700n
n = number of year
Answer:
p(t)=700t+7600

What is 6 1/3−1 2/3?
Answer:
4 2/3!
Step-by-step explanation:
Answer: [tex]4 \frac{2}{3}[/tex]
Step-by-step explanation:
Lets start by subtracting 6 by 1.
6 - 1 = 5
Now we need to subtract 1/3 by 2/3. Which means we will need to take one from the 5 and add it to the 1/3. So we get [tex]1 \frac{1}{3}[/tex]. Now we subtract 1 1/3 by 2/3. The answer to that is 2/3.
So our answer is 4 2/3

Step-by-step explanation:
f = {(x, y): y = 2x + 3} and D= {2, 4, 6} then, find Range of f
Answer:
R= {7, 11, 15}
Step-by-step explanation:
Since we already know what the Domain is for f (2, 4, 6) we can use that to get the range
Since the domain is also x let's replace x for 2
y=2(2)+3= 4+3=7
One of the range is 7
Replace x for 4
y=2(4)+3= 8+3= 11
One of the other range is 11
Replace x for 6
y= 2(6)+3= 12+3= 15
The last range is 15
So the range is R= {7, 11, 15}

x + y = 2
2x+ 7y = 9
Answer:
x=1 y=1
Step-by-step explanation:
(x + y = 2)×2
2x+ 7y = 9
2x + 2y = 4
2x+ 7y = 9
-5y =-5
y= 1
2x+7(1)=9
2x=2
x=1

What is 1 1/2 divided by 2
Answer:
3/4
Step-by-step explanation:
1 1/2 can be expressed as an improper fraction 3/2
hence
1 1/2 ÷ 2
= 3/2 ÷ 2
= 3/2 x 1/2
= 3/4

Which inequality is equivalent to this one? I WILL GIVE BRAINLEIST
y minus 8 less-than-or-equal-to negative 2
y minus 8 + 8 greater-than-or-equal-to negative 2 + 8
y minus 8 + 8 less-than negative 2 + 8
y minus 8 + 2 less-than-or-equal-to negative 2 + 8
y minus 8 + 2 less-than-or-equal-to negative 2 + 2
Answer:
y minus 8 + 2 less-than-or-equal-to negative 2 + 2
Step-by-step explanation:
Which inequality is equivalent to this one?
y minus 8 less-than-or-equal-to negative 2
y minus 8 + 8 greater-than-or-equal-to negative 2 + 8
y minus 8 + 8 less-than negative 2 + 8
y minus 8 + 2 less-than-or-equal-to negative 2 + 8
y minus 8 + 2 less-than-or-equal-to negative 2 + 2
Take the last option:
y minus 8 + 2 less-than-or-equal-to negative 2 + 2
remove the +2 on each side to get
y minus 8 less-than-or-equal-to negative 2
A new car is purchased for 19000 dollars. The value of the car depreciates at 11.25% per year. What will the value of the car be, to the nearest cent, after 14 years.
Answer:
$3573. 64
Step-by-step explanation:
Convert 11.25% to the decimal fraction 0.1125. Then subtract this result from 1.0000: 0.8875.
After 14 years, the formerly $19000 car will have the value
$19000(0.8875)^14 = $3573. 64

Sam manages a clothing boutique and has an annual salary of $23600. Doug works in a shoe store and is paid 9.40/h each week. Who has the higher gross income each month?
Answer:
Sam earns more money than Doug in an year
Step-by-step explanation:
The complete question is -
Sam manages a clothing boutique and has an annual salary of $23600. Doug works in a shoe store and is paid 9.40/h for 40 hours each week. Who has the higher gross income each month?
Solution -
Sum of money (in dollars) earned by Doug in one week is equal to
[tex]= 9.40 *40\\= 376[/tex]
Sum of money (in dollars) earned by Doug in one year is equal to
[tex]= 376 * 52 \\= 19552[/tex]
Hence, Sam earns more money than Doug in an year
