Just do the inverse of the translation

so by using the translation
(x-5, y+8), triangle A'B'C' will become triangle ABC

The number of users on a website is 630 and is growing exponentially at a rate of 76% per year. Write a function to represent th
Dafna1 [17]

The exponential function that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

The daily rate of change is of 20.82%.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

For this problem, the parameters are given as follows:

A(0) = 630, r = 0.76

Hence the equation that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

An year has 365 days, hence the rate of change per day is given by:

76/365 = 0.2082 = 20.82%.

The daily rate of change is of 20.82%.

UGHH I always get stuck on solving these system of equations, help me?!
ASHA 777 [7]
First one:
2x + y = -7-1
2x + x + 10 = -8
3x + 10 = -8
3x = -18
x= -6

Lunna [17]
Hi! First, we multiply both sides by 5, -n/5*5=5*5=-n=25. Second, we divide both sides by -1, -n/-1=25/-1. Therefore, our answer is n=-25
