30 POINTS! Consider the system of linear equations and the matrix equations below.

fiasKO [112]

Answer:

Option C is correct.

Step-by-step explanation:

-x+3y=2

4x-2y=22

In matrix form is represented as:

$\left[\begin{array}{cc}-1&3\\4&-2\end{array}\right] \left[\begin{array}{c}x&y\end{array}\right] =\left[\begin{array}{c}2&22\end{array}\right]$

AX=B

$X = A^{-1}B$

$A^{-1} = |A|/Adj A$

|A| = (-1)(-2)-(3)(4)

|A| = 2-12

|A| = -10

Adj A = $\left[\begin{array}{cc}-2&-3\\-4&-1\end{array}\right]$

A^-1 = -1/10 $\left[\begin{array}{cc}-2&-3\\-4&-1\end{array}\right]$

A^-1 = 1/10 $\left[\begin{array}{cc}2&3\\4&1\end{array}\right]$

X= A^-1 B

X = 1/10 $\left[\begin{array}{cc}2&3\\4&1\end{array}\right]$ $\left[\begin{array}{c}2&22\end{array}\right]$

X=1/10 $X=1/10\left[\begin{array}{c}2*2+3*22\\4*2+1*22\end{array}\right]\\X=1/10\left[\begin{array}{c}4+66\\8+22\end{array}\right]\\X=1/10\left[\begin{array}{c}70\\30\end{array}\right]\\X=\left[\begin{array}{c}70/10\\30/10\end{array}\right]\\X=\left[\begin{array}{c}7\\3\end{array}\right]$

So, x = 7 and y =3

Hence Option C is correct.

Bernardo is converting a fraction, StartFraction a Over b EndFraction, to a percent. Both a and b are whole numbers and not equa

anyanavicka [17]

Answer:

$Percent = \frac{100a}{b}\%$

Step-by-step explanation:

Given

$\frac{a}{b}$

Required

Convert to fraction

To do this, we simply multiply the fraction by 100%

This gives:

$Percent = \frac{a}{b} * 100\%$

$Percent = \frac{a * 100}{b}\%$

$Percent = \frac{100a}{b}\%$

The expression cannot be further simplified.

Take for instance the fraction is: $\frac{2}{5}$

Using the same analysis, the percentage would be:

$Percent = \frac{2}{5} * 100\%$

$Percent = \frac{2 * 100}{5}\%$

$Percent = \frac{200}{5}\%$

$Percent = 40\%$

What is the solution to the equation

irakobra [83]

Answer:

x = 12

Step-by-step explanation:

5(x - 6) = 2(x + 3)

Distribute

5x - 30 = 2x + 6

Put like terms on each side by subtracting both sides by -2x and adding 30 on each side

3x = 36

Simplify

3x/3 = 36/3

x = 36/3

x = 12

Plug is back in to check

5(12) - 30 = 2(12) + 6

60 - 30 = 24 + 6

30 = 30
