<span>(3x+y)/z = 2

Get rid of the z first.

3x + y = 2z

Then the y.

3x = 2z - y

Then divide both sides by 3 to isolate x.

x = 2/3z - 1/3y</span>

Answer:

After 4 days, the number of people attending both conferences be the same.

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$f(x) = 7+2x$

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$g(x) =11+x$

Both conference will have same number of people when

$f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4$

Thus, after 4 days, the number of people attending both conferences be the same.

The population function of the Western Lowland Gorillas can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

So, I will give a general explanation to solve the question

A population function can be represented as:

$y = a(1 \pm r)^x$

Where:

The initial population of the Western Lowland Gorillas is represented by (a)
The rate at which the population changes is represented by (r)
The number of years since 2022 is represented by (x)
The population in x years is represented by (y)

From the question, we understand that the population of the Western Lowland Gorillas decreases.

This means that the rate of the function would be an exponential decay i.e. 1 -r

Take for instance:

$y = 2000 * 0.98^x$
