. Find the inverse of the function below on the given interval and write it in the form yequalsf Superscript negative 1 Baseline

Elena L [17]

Answer:

The inverse of the function is $f^{-1}(x)=\frac{x-5}{3}$ .

Step-by-step explanation:

The function provided is:

$f (x)=3x+5$

Let $f(x)=y$ .

Then the value of x is:

$y=3x+5\\\\3x=y-5\\\\x=\frac{y-5}{3}$

For the inverse of the function, $x\rightarrow y$ .

⇒ $f^{-1}(x)=\frac{x-5}{3}$

Compute the value of $f[f^{-1}(x)]$ as follows:

$f[f^{-1}(x)]=f[\frac{x-5}{3}]$

$=3[\frac{x-5}{3}]+5\\\\=x-5+5\\\\=x$

Hence proved that $f[f^{-1}(x)]=x$ .

Compute the value of $f^{-1}[f(x)]$ as follows:

$f^{-1}[f(x)]=f^{-1}[3x+5]$

$=\frac{(3x+5)-5}{3}\\\\=\frac{3x+5-5}{3}\\\\=x$

Hence proved that $f^{-1}[f(x)]=x$ .

The equation y = 2.50x determines the total cost, y, of buying x carnival tickets. Use the drop-down menu to complete the senten

PIT_PIT [208]

Answer: The total cost of 15 carnival tickets=$37.50

Step-by-step explanation:

We are given that ,

The equation $y = 2.50x$ represents the total cost of buying buying carnival tickets , where x= Number of carnival tickets and y= Total cost.

To find : The cost of 15 carnival tickets.

In the given equation , we substitute the value of x = 15 we get

$y = 2.50(15)=2.50\times15=37.5\\\Rightarrow\ y=37.5$

Thus , According to the equation, the total cost of 15 carnival tickets= $ 37.50

Hence , the correct answer is $ 37.50 .

1. Simplify the expression: 4+36+(10-8)’-3+7 A. 130 B. 100 C. 38 D. 37

Alika [10]

Answer:

The answer isn't in the options anyway I'll write it. the answer is 46.

Step-by-step explanation:

According to BODMAS rule - addition should be done first so

4+36= 40 and -3 +7 = 4 so 40+4 ,= 44

then we should do subtracting so, 10-8 = 2

to conclude we should bring the equation to an end so,

44+2 = 46
