This is an easy 1 step equation. You just have to add 9 to each side to cancel out the -9. Then you add 9 to 3. 9 + 3= 12. Hope this helps. The work is below.

-9 + _ = 3
+9        +9

_ =  12

Solve for x.(x+1)(3x+4)=0
TiliK225 [7]

Answer:

(X + 1) (3X + 4 ) =0

3X + 4X + 3X + 4 = 0

Add

10X + 4 = 0

10X = 0 - 4

10X = -4

divide both sides by 10

10x/10 = -4/10

X = 2/5

Find the reduced echelon form of [1, 2, 4; 0, 3, 6; 0, 2, 4]
taurus [48]

Answer:

\begin{pmatrix}1&0&0\\0&3&6\\0&0&0 \end{pmatrix}

Step-by-step explanation:

Given:

\begin{pmatrix}1&2&4\\0&3&6\\0&2&4 \end{pmatrix}

We need to reduce the given matrix to reduced echelon form.

Solution:

Make zeroes in column 1 except the entry at row 1, column 1. As we can see all elements in column are already zero. Make zeroes in column 2 except the entry at row 2, column 2.

\begin{pmatrix}1&2&4\\0&3&6\\0&2&4 \end{pmatrix}\\R_3\rightarrow R_3-\frac{2}{3}R_2\\\begin{pmatrix}1&2&4\\0&3&6\\0&0&0 \end{pmatrix}\\R_2\rightarrow \frac{R_2}{3}\\\begin{pmatrix}1&2&4\\0&1&2\\0&0&0 \end{pmatrix}\\R_1\rightarrow R_1-2R_2\\\begin{pmatrix}1&0&0\\0&3&6\\0&0&0 \end{pmatrix}\\

So, \begin{pmatrix}1&2&4\\0&3&6\\0&2&4 \end{pmatrix} in reduce echelon form is \begin{pmatrix}1&0&0\\0&3&6\\0&0&0 \end{pmatrix}
