Which equation(s) model inverse variation? Select all that apply.

Harman [31]

For this case, what you should know is that the equations that represent an inverse variation are those that could not form a straight line, for example.

We have then:

Equation 1:

pv = 13

Rewriting:

p = 13 / v

P and v are represent an inverse variation.

Equation 2:

z = (2 / x)

z and x are represent an inverse variation.

Answer:

equations represented inverse variation are:

pv = 13

z = (2 / x)

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too

Eddi Din [679]

Answer:

$\Large \boxed{ -x+65}$

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

$\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}$

$\displaystyle m=\frac{55-65}{10-0}=-1$

Use slope-intercept form

$y=mx+b$

$y=-1x+b$

<em>b</em> is the y-intercept, y-intercept is (0,65)

$y=-1x+65$

A hot air balloon went from an elevation of 6,678 feet to an elevation of 3,438 feet in 48 minutes. What was its rate of descent

gregori [183]

Answer:

The rate of descent is $-67.5\frac{feet}{minute}$

Step-by-step explanation:

we know that

The formula to calculate the rate or slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Let

x------> the time in minutes

y----> the elevation in feet

we have

$A(0,6,678)\ B(48,3,438)$

Substitute the values

$m=\frac{3,438-6,678}{48-0}$

$m=\frac{-3,240}{48}$

$m=-67.5\frac{feet}{minute}$
