$\left[\begin{array}{ccc}2&6&3\\-5&1&4\end{array}\right]$

R1 ÷ 2 = $\left[\begin{array}{ccc}1&3&1.5\\-5&1&4\end{array}\right]$

R2 ÷ -5 = $\left[\begin{array}{ccc}1&3&1.5\\1&-0.2&-0.8\end{array}\right]$

R2: R1 - R2 = $\left[\begin{array}{ccc}1&3&1.5\\0&3.2&2.3\end{array}\right]$

R2 ÷ 3.2 = $\left[\begin{array}{ccc}1&3&1.5\\0&1&0.71875\end{array}\right]$

R1: R1 - 3R2 = $\left[\begin{array}{ccc}1&0&0.65625\\0&1&0.71875\end{array}\right]$

Answer: x = 0.65625, y = 0.71875

Please help! It’s Saturday and I only have this question left on my digital worksheet!

Natalija [7]

Answer:

<h2>The answer is option C</h2>

Step-by-step explanation:

<h3> $\frac{ {6}^{ - 3} }{ {6}^{5} }$ </h3>

Using the rules of indices

Since the bases are the same and are dividing we subtract the exponents

That's

<h3> $\frac{ {a}^{x} }{ {a}^{y} } = {a}^{x - y}$ </h3>

So we have

<h3> $\frac{ {6}^{ - 3} }{ {6}^{5} } = {6}^{ - 3 - 5} = {6}^{ - 8}$ </h3>

Using the rules of indices

<h3> ${x}^{ - y} = \frac{1}{ {x}^{y} }$ </h3>

So we have the final answer as

<h2> $\frac{1}{ {6}^{8} }$ </h2>

Hope this helps you
