It is not appropriate because it isn't reflective of the points on the right side and its deviation from the points, which has an obvious positive correlation, is too great to be a line of best fit. To make it better, make it less steep and start the line close to the origin.

Consider the function.

Answer:

Option 4

Step-by-step explanation:

Given function is,

$f(x)=2\frac{1}{2}-3\frac{1}{3}x$

Steps to get the inverse of the given function,

Step 1,

Convert the function into equation,

$y=2\frac{1}{2}-3\frac{1}{3}x$

Step 2,

Interchange the variables 'x' and 'y',

$x=2\frac{1}{2}-3\frac{1}{3}y$

Step 3,

Solve the equation for the value of y,

$x-2\frac{1}{2}=-3\frac{1}{3}y$

$x-\frac{5}{2}=-\frac{10}{3}y$

$-x+\frac{5}{2}=\frac{10}{3}y$

$-3x+\frac{15}{2}=10y$

$-\frac{3}{10}x+\frac{15}{20}=y$

$y=-\frac{3}{10}x+\frac{3}{4}$

Step 4,

Convert the equation into inverse function,

$f^{-1}x=-\frac{3}{10}x+\frac{3}{4}$

For x-intercepts,

Substitute y = 0,

$0=-\frac{3}{10}x+\frac{3}{4}$

$\frac{3}{10}x=\frac{3}{4}$

$x=\frac{10}{4}$

$x=\frac{5}{2}$

$x=2\frac{1}{2}$

Therefore, x-intercept of the inverse function is $(2\frac{1}{2},0)$ .

Option 4 will be the answer.

Kay [80]

If it is 699.00 on e bay and the markup is 30 percent then you would have to kind of subtract

PLEASE HELP ME WITH THIS KHAN ASAP<br><br><br><br><br>I did 5 hours of Khan :(

Answer:

The functions have the same y-intercept.

OPTION C is correct.

Step-by-step explanation:

<u>DEFINITIONS AND FORMULAS</u>

The equation of a linear graph is given to be:

$y=mx+b$

Where m is the slope of the graph and b is the y-intercept.

To calculate the slope given a table, we can use the formula:

$m=\frac{y^{2}-y^{1} }{{}x^2 -x^1}$

<u>SOLUTION</u>

<u>Function 1:</u> The equation of the graph is given to be

$p=-\frac{3}{2}r-5$

Therefore, the y-intercept of the graph is given to be:

$b=-5$

<u>Function 2: Recall that the y-intercept of a graph is the y-value when x = 0.</u>

On checking the graph, we can see that when r = 0, p = -5.

Therefore, the y-intercept is:

$b=-5$

ANSWER

The functions have the same y-intercept.

OPTION C is correct.
