Which row operation will triangularize this matrix?
Ludmilka [50]
Triangularizing matrix gives the matrix that has only zeroes above or below the main diagonal. To find which option is correct we need to calculate all of them.
In all these options we calculate result and write it into row that is first mentioned:

A)R1-R3
\left[\begin{array}{ccc}-1&0&0|0\\0&1&1|6\\2&0&1|1\end{array}\right]

B)2R2-R3
\left[\begin{array}{ccc}1&0&1|1\\-2&2&1|4\\2&0&1|1\end{array}\right]

C)-2R1+R3
\left[\begin{array}{ccc}0&0&-1|-1\\0&1&1|6\\2&0&1|1\end{array}\right]

D)2R1+R3
\left[\begin{array}{ccc}4&0&3|3\\0&1&1|6\\2&0&1|1\end{array}\right]

E)3R1+R3
\left[\begin{array}{ccc}5&0&4|4\\0&1&1|6\\2&0&1|1\end{array}\right]

None of the options will triangularize this matrix. The only way to <span>triangularize this matrix is
R3-2R1
</span>\left[\begin{array}{ccc}1&0&1|1\\0&1&1|6\\0&0&-1|-1\end{array}\right]
<span>
This equation is similar to C) but in reverse order. Order in which rows are written is important.</span>

A toy jeep is 12 1/2 inches long while an actual jeep measures 18 3/4 feet long. What is the value of the ratio of the length of
mojhsa [17]
<span> A toy jeep is 12 1/2 inches
Actual jeep is 18 ¾ feet long
before we determine the ratio, let’s convert first each size into the same unit of measure and decimal points

=> 12 ½ = 25/2
=> 12.5 inches
=> 18 ¾ = 75/4
=> 18.75 feet
Now, let’s convert feet to inches to know the ratio
=> 1 foot = 12 inches
=>  12.5 inches : 225 inches
 => 225 / 12.5
=> 18 inches
thus in every 1 inch of toy car represents  1.5 feet of actual car.
