According to the distributive property, 6 (a + b) =

Its b

because this is how the distributive property works....
i'm going to use 2 and 4 for example
6(2+4)= 36 because you add 2 and 4(or a and b) then multiply by 6 because when using the <span>distributive you use pemdas which is an abbreviation for parenthesis, exponents, multiplication, division, addition and subtraction and that is the order you do it in

o answer b you multiply 6 by a (or 2) then multiply 6 by b (or 4) after doing that you add them together and it equals 36 just like 6(2+4) (or 6(a+b)..)
and that is why it is b</span><span />

The answer is option B. In the distributive property you need to multiply the constant that is outside of the parenthesis, with the terms that are inside :)

Which of the following matrices is the solution matrix for the given system of equations? x + 5y = 11 x - y = 5

givi [52]

<h2>The required solution is x = 6 and y = 11 </h2>

Step-by-step explanation:

Given system of equations are

x+5y = 11 and x-y =5

$A= \left[\begin{array}{cc}1&5\\1&-1\end{array}\right]$ $X=\left[\begin{array}{c}x\\y\end{array}\right]$

and $B= \left[\begin{array}{c}11\\5\end{array}\right]$

∴AX=B

$adj A = \left[\begin{array}{cc}{-1}&{-5}\\{-1}&1\end{array}\right]$

$A= \left|\begin{array}{cc}1&5\\1&-1\end{array}\right|=-6$

∴ $A^{-1} =\frac{adj A}{|A|}$

So, $A^{-1} =\frac{ \left[\begin{array}{cc}{-1}&{-5}\\{-1}&1\end{array}\right]}{-6}$

$A^{-1} ={ \left[\begin{array}{c \c} {{\frac{1}{6} }}&{\frac{5}{6}}\ \\ {{\frac{1}{6} }}&{\frac{-1}{6}} \end{array}\right]}$

$X =A^{-1}\times B$

⇒ $\left[\begin{array}{c}x\\y\end{array}\right] ={ \left[\begin{array}{c \c} {{\frac{1}{6} }}&{\frac{5}{6}}\ \\ {{\frac{1}{6} }}&{\frac{-1}{6}} \end{array}\right]} \times \left[\begin{array}{c}11\\5\end{array}\right]$
