Usando un sistema de ecuaciones, se encuentra que ese número es n = -3 o n = 3.
<h3>¿Qué es un sistema de ecuaciones?</h3>
Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.
En este problema, la variable es el número n.
El quintuple de un número cuadrado disminuido en 9 da como resultado 36, o sea, la ecuación es:
5n² - 9 = 36
5n² = 45
n² = 9
n = -3 o n = 3.

We have
f(x)=(x-7)/(x²<span>-7x-8)
resolving the quadratic equation
using a graph tool-------- > see the attached figure
x=-1 x=8
therefore
</span>(x-7)/(x²-7x-8)=(x-7)/[(x+1)*(x-8)
the answer is -1 and 8
Answer:
you have to find only one example in which the conjecture is not true.
Answer:
2 + n ÷ 5 = 8
Step-by-step explanation:
Just by looking at what the exercise is saying, "quotient" tells you that you will be dealing with division. The rest is simple.

Answer:
The expression that represents the population of elk is:
. It'll take 6 years for the population to reach 1,458 individuals.
Step-by-step explanation:
Since the number of elks triples every year and starts at
, then after the first year the population will be:

While on the second year, it'll be:

On the third year:

And so on, therefore the expression that describes the population of elk as the years passes is:

If we want to know the number of years until the population reach 1,458 elk, we need to apply this value to the left side of the equation and solve for t.

The population will reach 1,458 elk in 6 years.
