the population of masterton was 23 000 in 2012. Assume that Masterton population increases at a rate of 2% per year. Write an equation to model the population of masterton (y) based on number of years since 2012(x)
Answers
23 000*1.02 (which is 23460 people).
And after two years it will be:
23460*1.02, which is 23930 people. Another way of writing it is
23000*1.02*1.02
so we can generalize: the population of the town, y= 23 000*
where x is the number of years passed

Giving 15 points for help!Mr. Yi buys vegetables at a market. He purchases 6 pounds of potatoes, p, and 3 pounds of onions, n, for $18. Onions cost twice as much as potatoes. To determine the unit price for each item, his daughter sets up and solves the system of equations shown. 6p + 3n = 18 and 2n = p 6(2n) + 3n = 18 12n + 3n = 18 15n = 18; n = $1.20 Onions cost $1.20 per pound. Analyze the daughter’s solution. Which statements are true? Check all that apply. The equation 2n = p should be 2p = n. The equation 6p + 3n = 18 should be 6n + 3p = 18. The actual cost of the onions is $3.00 per pound. Potatoes cost $0.60 per pound. Potatoes cost $1.50 per pound. Potatoes cost $2.40 per pound.

nth term
Answer:
(6^(n-1))/6
Step-by-step explanation:
The nth term of a geometric series is a function of the number n, the common ratio between each successive number in the series r and the first term a. This may be expressed mathematically as
= a(r)^n-1
Given the series,
a = 1/6,
r = T2/T1 = 1/1/6 = 6
The nth term
= (1/6)(6)^n-1
= (6^(n-1))/6

x² ⇒ x * x
-5 ⇒ -5 * 1
-4 ⇒ -5 + 1
(x + 1)(x - 5) = x(x-5) + 1(x-5)
x² - 5x + 1x - 5 = x² - 4x - 5
x + 1 = 0
x = -1
x - 5 = 0
x = 5
y = x² - 4x - 5
y = -1² - 4(-1) - 5
y = 1 + 4 - 5
y = 5 - 5
y = 0
y = x² - 4x - 5
y = 5² - 4(5) - 5
y = 25 - 20 - 5
y = 0
