Answer:

8x^2 - 26x - 10

Step-by-step explanation:

3(6x2 + 3x - 5 ) = 18x^2 + 9 -15

5(2x2 + 7x - 1) = 10x^2 + 35 - 5

18^2 - 10x^2 = 8x^2

9x - 35x = - 26x

-15 -(-5) = -10

final answer = 8x^2 - 26x - 10

The average rate of change is just change in y divided by change in x.

(f(4)-f(-1))/(4--1)

(16-8-4-1-2+4)/5

5/5

1

So the average rate of change is just 1.

You make a $15 payment on your loan of $500 at the end of each month
lara [203]

Answer:

2.8 years or 33.6 months.

Step-by-step explanation:

I am not sure what your questions is, but I assume it is how long it will take to pay it off?

In a year (15*12,) you would have paid $180 of it.

x = 500/180

Therefore, it will take you approximately 2.8 years to pay off your loan, excluding interest, of course, since you did not provide that rate.

3 times a number is 54 less than the square of that number. Find the negative solution.
son4ous [18]

Answer:

-6

Step-by-step explanation:

3n = n² - 54

n² - 3n - 54 = 0

n² - 9n + 6n - 54 = 0

n(n - 9) + 6(n - 9) = 0

(n - 9)(n + 6) = 0

n = 9 , -6
