What is the determinant of the coefficient matrix of the system
vovikov84 [41]

The coefficient matrix is

\begin{bmatrix}-1&-1&2\\3&2&-1\\4&4&-8\end{bmatrix}

Its determinant is then

\det\begin{bmatrix}-1&-1&2\\3&2&-1\\4&4&-8\end{bmatrix}=-4\det\begin{bmatrix}-1&-1&2\\3&2&-1\\-1&-1&2\end{bmatrix}

which is equal to 0.

Donna and Kaia are playing a game involving two fair number cubes with faces labeled 1 through 6. If Donna tosses a sum of 8 on
Rainbow [258]
To get a sum of eight the first die must be 2 or greater and the second die must be one specific value that makes the sum equal to 8 with respect to the first die.

So the probability of Donna winning on her next turn, rolling a sum of 8 is:

(5/6)(1/6)=5/36

Solve for x<br><br> -0.3(0.7x - 0.9) = -1.83<br><br> A.) -10<br> B.) -1<br> C.) 1<br> D.) 10
Licemer1 [7]
Hello!

That problem looks pretty messy... let's clean it up! :D

so we have this   ----->  -0.3(0.7x - 0.9) = -1.83        let's get simplifying
 
-0.21x + 0.27 = -1.83    ----->    I distributed the -0.3 among 0.7x and -0.9
-0.21x = -2.1                  ----->    I subtracted 0.27 on both sides of the equation
<u>x = 10</u><u />                             ----->    I divided -0.21 on both sides of the equation

The answer you're looking for is D!

I hope this helps! :D
