The correct answer for this statement would be TRUE. Yes,it is true that the identity function is a linear function. <span>A linear function is a map between two vector spaces that preserves vector addition and scalar multiplication.  
</span>this means f(x + y) = f(x) + f(y) and f(xy) = f(x)f(y)) 
<span>The identity function is the function such that f(x) = x 
</span>So by using this example, we can conclude that it is a linear function.

Answer:

True

Step-by-step explanation:

An identity function is a function such that y=f(x)=x.

The identity is a linear function with pending m=1. This means that the function  passes through the origin of coordinates, the point (0,0).

m=1 > 0 then, the function is growing.

m=1 means that if we increase x in 1 then y also increases in 1 unit and the graph of the function forms an angle of 45 degrees with any of the axes.

The function is y=x and the graph is:

Answer:

x= 99

Step-by-step explanation:

first we open brackets

6x+36=7x-63

transpose

6x-7x= -63-36

-x=-99

the signs cancel each other so

x= 99

You decide to put $5000 in a savings account to save $6000 down payment on a new car. If the account has an interest rate of 7%
bezimeni [28]

\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill&\$6000\\ P=\textit{original amount deposited}\dotfill &\$5000\\ r=rate\to 7\%\to \frac{7}{100}\dotfill &0.07\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\dotfill &12\\ t=years \end{cases}

\bf 6000=5000\left(1+\frac{0.07}{12}\right)^{12\cdot t}\implies \cfrac{6000}{5000}\approx (1.0058)^{12t}\implies \cfrac{6}{5}\approx(1.0058)^{12t} \\\\\\ \log\left( \cfrac{6}{5} \right)\approx \log[(1.0058)^{12t}]\implies \log\left( \cfrac{6}{5} \right)\approx 12t\log(1.0058) \\\\\\ \cfrac{\log\left( \frac{6}{5} \right)}{12\log(1.0058)}\approx t\implies 2.63\approx t\impliedby \textit{about 2 years, 7 months and 16 days}

Wewaii [24]

Answer:

Solteros= 27

Step-by-step explanation:

<u>Entiendo que de los 120 tripulantes, sobrevivió el 30%. Y de los sobrevivientes, 25% son casados.</u>

<u></u>

Primero, debemos calcular la cantidad de sobrevivientes:

Sobrevivientes= 120*0.3= 36

Ahora la cantidad de casados, y por diferencia los solteros:

Casados= 36*0.25= 9

Solteros= 36 - 9

Solteros= 27
