Answer:

D

Step-by-step explanation:

If there is a 2x2 matrix as $\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]$

The determinant is given by $\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right]$

<em>Now, if we calculate the value of "ad - bc", we see that:</em>

$(-4)(-12)-(8)(6)=0$

We can't calculate the inverse, the inverse doesn't exist. The answer is D.

the side length of the state flag of Colorado are in the ratio of 2:3 if the flag is 12 ft long what is the height?

yanalaym [24]

Answer:

The height is 8

Step-by-step explanation:

Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.

Make the equation.

$\frac{2}{3} = \frac{x}{12}$

Now isolate x (in order to solve for it)

$12 * \frac{2}{3} = \frac{x}{12}*12\\8 = x$

x= 8

The height is 8.

8/12 = 2/3 ✅

Inversely proportional : it is relationship between two variables in which when one variable's value is increasing than other one is decreasing.

Situation A : The number of miles Rashid drives increases over a period of 5 hours.

→ in this situation both variable no. of miles and period of time are increasing. so it is not represent a inversely proportional relationship.

in next two situation , two variables are increasing with each other.

so we take last situation ↓

Situation : Robin has $100 to share evenly with his cousins at the fair. As the number of cousins who arrive increases, the amount that each person receives

decreases.

→ in this situation , both variable viz no. of cousins and amount they got is inversely proportional to each other. when no. of cousins are increasing than amount is decreasing. so this last one situation represent the inversely proportional relationship.
