Answer:An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing.

What is the slope of (-9, 8) and (3,- 12)
earnstyle [38]

Answer:

Your slope would be -5/3

Step-by-step explanation:

To find the slope from two points, you would use the formula y2-y1/x2-x1

In this case, the equation would look like -12-8/3-(-9)

-12 - 8 = -20

3 - (-9) = 12

-20/12 = -5/3

Assume that y varies directly with x. If y=1/4 when x=1/8, find x when y= 3/16
prisoha [69]
Y=kx

Step 1: find the value of k

1/4=k(1/8)
k=2

Step 2: find the value of x using y=2x

y=2x
3/16= 2x
x= 3/32

Solved.

Write the equation for a line that has an initial value of 3 and 3/4 as it’s rate of change
frutty [35]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

initial value of 3, namely when x = 0, y = 3, so we have the point (0 , 3) and it has a rate or slope of 3/4.

(\stackrel{x_1}{0}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{3}{4} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{\cfrac{3}{4}}(x-\stackrel{x_1}{0})\implies y=\cfrac{3}{4}x+3

On a bike trip across the United States, Ronney notes that he covers about 190 miles every 4 days. If he continues at this rate,
Westkost [7]

Using a ratio table to determine the number of miles that Ronney could bike in 6 days as <u>285 miles</u> is as follows:

<h3>Ratio Table:</h3>

Day                 Miles Biked

Day One            47.5

Day Two           95.0

Day Three       142.5

Day Four         190.0

Day Five         237.5

Day Six          285.0

<h3>What is a ratio table?</h3>

A ratio table is a structured list of equivalent (equal value) ratios that explain the relationship between the ratios and the numbers.

<h3>Data and Calculations:</h3>

Day                 Miles Biked

Day One            47.5 (190/4)

Day Two           95.0 (190/4 x 2)

Day Three       142.5 (190/4 x 3)

Day Four         190.0 (190/4 x 4)

Day Five         237.5 (190/4 x 5)

Day Six           285.0 (190/4 x 6)

Thus, in six days, Ronney biked <u>285 miles</u> based on the ratio table.
