Answer:

y =-3000x +12000

Step-by-step explanation:

answer is

1)   12000 is the constant therefore when the number of hours is 0 the tickets are 12000

2)  the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000  (negative because it is reducing)

Find three consecutive positive integers such that the sum of their squares is 2354. What is the largest integer?
Ilya [14]

Answer:

The largest integer is 29.

Step-by-step explanation:

Let the consecutive positive integers are x, x+1 and x+2.

The square of sum of squares of three consecutive positive integers is 2354 such that,

x^2+(x+1)^2+(x+2)^2=2354\\\\x^2+x^2+2x+1+x^2+4+4x=2354\\\\3x^2+6x+5=2354\\\\3x^2+6x- 2349=0

It is a quadratic equation whose solution is given by :

x = 27 and x = -29

First positive integer = 27

Second positive integer = 27+1 = 28

Third positive integer = 27+2 = 29

Hence, the largest integer is 29.

Umnica [9.8K]

Answer:

$241.58

Step-by-step explanation:

he amount of money A, accrued at the end of n years when a certain amount, P is invested at a compound annual rate, r, is given by:

A=P(1+r)^n

From the given information:

P =$150

r=10%=0.1

n= 5 years

Therefore the balance after 5 years is:

A=P(1+r)^n\\=150(1+0.1)^5\\=150*1.1^5\\=\$241.58
