To the nearest tenth of a percentage what is 3/11 written as a percent

Given that f(x) = x + 3<br> a) Find f(2)

Nataly_w [17]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

Here we go ~

In the above question, it is given that :

$\qquad \sf \boxed{ \sf f(x) = \frac{x + 3}{2} }$

A.) Find f(2) :

$\qquad \sf \dashrightarrow \: f(2) = \dfrac{2 + 3}{2}$

$\qquad \sf \dashrightarrow \: f(2) = \dfrac{5}{2}$

or

$\qquad \sf \dashrightarrow \: f(2) = 0.5$

B.) Find ${ \sf {f}^{-1}(x) }$ :

$\qquad \sf \dashrightarrow \: let \: y = f (x)$

so, we can write it as :

$\qquad \sf \dashrightarrow \: y = \dfrac{x + 3}{2}$

$\qquad \sf \dashrightarrow \: 2y = x + 3$

$\qquad \sf \dashrightarrow \: x = 2y - 3$

Now, put x = ${ \sf {f}^{-1}(x) }$ , and y = x and we will get our required inverse function ~

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(x) = 2x- 3$

C.) Find ${ \sf {f}^{-1}(12) }$ :

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(12) = 2(12)- 3$

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(12) = 36- 3$

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(12) = 33$

Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional drag-and-drop no

andreyandreev [35.5K]

Answer:

Proportionality constant = $\frac{3}{2}$

Step-by-step explanation:

Let y ∝ x

y = kx

Here, k = proportionality constant

From the table attached,

If x = 2 and y = 3,

3 = 2k

k = $\frac{3}{2}$

If x = 4 and y = 6,

6 = 4k

k = $\frac{6}{4}$

k = $\frac{3}{2}$

Since, k = $\frac{3}{2}$ is constant in every condition, table represents the proportional relation with proportionality constant $\frac{3}{2}$ .
