-1 -1 | -12<br> -3 2 | 32<br> How would you put this into row echelon form ?
Dovator [93]

\left[\begin{array}{cc|c}-1&-1&-12\\-3&2&32\end{array}\right]

Multiply through row 1 by -1:

\left[\begin{array}{cc|c}1&1&12\\-3&2&32\end{array}\right]

Add 3(row 1) to row 3:

\left[\begin{array}{cc|c}1&1&12\\0&5&68\end{array}\right]

Multiply through row 2 by 1/5:

\left[\begin{array}{cc|c}1&1&12\\0&1&\frac{68}5\end{array}\right]

Add -1(row 2) to row 1:

\left[\begin{array}{cc|c}1&0&-\frac85\\&&\\0&1&\frac{68}5\end{array}\right]

Find the slope of the line.<br> 9x+y=9
Serggg [28]

Answer: -9/1

Step-by-step explanation: you want to get x and y on opposite sides so you subtract 9x and that gives you y=-9x+9 because the nine on the right side doesn’t have a negative in front of it so you know it’s positive. Your slope is whatever comes before the x so since it’s -9 that means it’s -9/1

What is the ordered pair solution for y&gt;= 1/3x+4
blondinia [14]

Answer:

Step-by-step explanation:

y > (1/3)x + 4 has an infinite number of solutions.  Draw a dashed line representing y = (1/3)x + 4 and then pick points at random on either side of this line.  For example, pick (1, 6).  Substitute 1 for x in y > (1/3)x + 4 and 6 for y.  Is the resulting inequality true?  Is 6 > (1/3)(1) + 4 true?  YES.  So we know that (1, 6) is a solution of y > (1/3)x + 4.  Because (1, 6) lies ABOVE the line y = (1/3)x + 4, we can conclude that all points abovve this line are solutions.

Are triangles DEF and LNM similar if DF = 8 and LM = 4?triangles LNM and DEF with angles N and E marked with the right angle sym
Sophie [7]

Answer:

Option D) No, there is not enough information

Step-by-step explanation:

We are given the following in the question:

A triangles DEF and triangle LNM

\angle N = \angle E = 90^\circ\\DF = 8\\LM = 4

Similarity of triangle can be proved in the following manner:

  1. AA
  2. SSS
  3. SAS

Since from the given information, it is not possible to prove the similarity of the triangles due to incomplete information, the triangles cannot be proved similar by any postulate.

Thus, the correct answer is

Option D) No, there is not enough information
