I need help please ASAP thank you

Answer:

The products of AB and BA is given by

AB= $\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]$

BA= $\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]$

Step-by-step explanation:

Given the matrices A= $\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right]$ and

B= $\left[\begin{array}{cc}1&-1\\-3&0\end{array}\right]$

To find the product AB and BA

AB= $\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right] \left[\begin{array}{cc}1 & -1\\-3 &0\end{array}\right]$

$=\left[\begin{array}{cc}6+15& -6+0\\-3+12&3-0\end{array}\right]$

Therefore the product of AB is

AB= $\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]$

BA= $\left[\begin{array}{cc}1&-1\\-3&0\end{array}\right]$ $\left[\begin{array}{cc}6&-5\\-3&-4\end{array}\right]$

$=\left[\begin{array}{cc}6+3& -5+4\\-18+0&15+0\end{array}\right]$

Therefore the product of BA is

BA= $\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]$

The products of AB and BA is given by

AB= $\left[\begin{array}{cc}21&-6\\ 9&3\end{array}\right]$

BA= $\left[\begin{array}{cc}9&-1\\-18&15\end{array}\right]$

Please help me 33/2 + 3y/5 = 7y/10 + 15

8090 [49]

We are given with an equation in variable y and we need to solve for y . So , now let's start !!!

We are given with ;

${:\implies \quad \sf \dfrac{33}{2}+\dfrac{3y}{5}=\dfrac{7y}{10}+15}$

Take LCM on both sides :

${:\implies \quad \sf \dfrac{165+6y}{10}=\dfrac{7y+150}{10}}$

Multiplying both sides by 10 ;

${:\implies \quad \sf \cancel{10}\times \dfrac{165+6y}{\cancel{10}}=\cancel{10}\times \dfrac{7y+150}{\cancel{10}}}$

${:\implies \quad \sf 165+6y=7y+150}$

Can be further written as ;

${:\implies \quad \sf 7y+150=165+6y}$

Transposing 6y to LHS and 150 to RHS

${:\implies \quad \sf 7y-6y=165-150}$

${:\implies \quad \bf \therefore \quad \underline{\underline{y=15}}}$
