Fill in the blank by performing the indicated elementary row operation(s).

Scilla [17]

In this question, we are given a matrix, and we have to perform the given operation.

The matrix is:

$\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]$

The following operation is given:

$R_1 \rightarrow -6R_2 + R_1$

In which $R_1$ is the element at the first line and $R_2$ is the element at the second line.

Updating the first line:

$R_{1,1} = -6*1 + 6 = 0$

$R_{1,2} = -6*-5 - 1 = 30 - 1 = 29$

$R_{1,3} = -6*0 + 5 = 5$

Thus, the filled matrix will be given by:

$\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]$

HELP!!! PLEASE ANSWER QUICK!!

Leto [7]

Answer:

Triangle ITA is the answer.

Step-by-step explanation:

<S = <I means that the triangle IRS is an isoscles.

The midpoint (T) cutting both congruent side length sides at the same angle means that Line TG and Line TA are equal.

Also T being the midpoint means Line TI = Line TS.

Given that angles <G and <A are same.

You can use SSA (side-side-angle) to prove triangles are congruent so line SG is equal to Line IA.
