The equation that is an example of inverse variation is B none

<h3>How to determine the equations that are direct variation?</h3>

There are several types of variations.

Some of them include:

Direct variation
Joint variation
Inverse variation

Equations that are inverse variation are represented as:

y = k/x

Where k represents the constant of proportionality or variation

From the list of options, none of the equations has the form y = k/x

Hence, the equation that is an example of inverse variation is B none

Together, Sarah's two cats have the same mass as her dog, 11 kg. The mass of one cat is

levacccp [35]

First, lets do all calculations in kg. 1kg=1000 grams
Lets set 1 cat's mass as x.
Lets set the other cat's mass as y.
1) x+y=11
2) y=x+1.5

Lets plug eq 2 into eq 1.
x+x+1.5=11
2x+1.5=11
2x=9.5
x=4.75 kg

If one cat weighs 4.75 kg, then the other must weigh 6.25 kg.

Which quadratic equation fits the data in the table? (PICTURE OF TABLE ATTACHED)

Paha777 [63]

The correct quadratic equation for that set of points is:
$y=x^2+7x+1$

To check it, simply put first and last pair of points and assure the equality:
$-11=(-3)^2+7*(-3)+1$
$-11=9-21+1$
$-11=-11$

$79=6^2+7*6+1$
$79=36+42+1$
$79=79$

GrogVix [38]

Answer:

X is a discrete

Step-by-step explanation:

Discrete variables that can only take on a finite number of values.

Values such are 0,1,2,3,4,5,...... etc.

Available customers at any point in time could be 0,1,2,3 , 13, 26, 100 etc.

So, we say that X is a discrete variable.
