Use the graph to write a linear function that relates y to x.
sergeinik [125]
The basic structure of a linear function is y=mx+b (or +c, depending on your schools curriculum)

We need to find the slope (m), and the y-intercept (b/c)

To find the slope you can pick two random points, say (2,2) and (0,1)

The formula for the slope is this: m= y1-y2 / x1-x2

So if we substitute the points in, we get 2-1 / 2-0 = 1/2

Knowing the slope, it can be substituted into to the equation: y=1/2x + b

Then, if you notice the second point- (0,1), it’s the y-intercept. The y coordinate there is 1.

To check if this is correct, a random coordinate set can be picked and substituted in to find b.

y= 1/2x + b
2 = 1/2 *2 + b
2 = 1 + b
2-1=b
1=b

Therefore, the final linear function is y = 1/2 x + 1

Find the inverse of each function<br><br> 1. f(x) = 4/(x+2) - 2<br><br> 2. f(x)= -2x^5 - 3
lisabon 2012 [21]

We are given the following function:

f(x) = 4/(x+2) - 2

We are asked to determine the inverse of this function. To do that we will first change the "f(x)" for "y":

y =  \frac{4}{x + 2}  - 2

Now we will switch "x" and "y", like this:

x =  \frac{4}{x + 2}  - 2

Now we will solve for "y", first by adding 2 to both sides:

x + 2 =  \frac{4}{y + 2}

Now we multiply both sides by "y+2":

(y + 2)(x + 2) = 4

Now we divide both sides by "x+2":

y + 2 =  \frac{4}{x + 2}

Now we subtract 2 to both sides:

y =  \frac{4}{x + 2}  - 2

Now we change "y" for the inverse of f(x), that is:

{f}^{ - 1} (x) =  \frac{4}{x + 2}  - 2

And thus we found the inverse. A similar procedure can be used for function 2.

The answer and how to do it.
Kruka [31]

let x = orginal price of the shorts

$21 = x(100%-20%) * 1.05

$21 = x(80%) * 1.05

$21 = 0.8x * 1.05

Subtract 1.05 from both sides

$19.95 = 0.8x

Divide 0.8 from both sides

$24.9375 = x

So the orginal price of the shorts are about $24.94
