2x + y - z = -8
Andreyy89

Answer:

Multiply row 1 by \frac{1}{2}.

Step-by-step explanation:

The augmented matrix of the system of linear equation is described below:

\left[\begin{array}{cccc}2&1&-1&-8\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]

Where a_{11} = 2, if we need to create a_{11} = 1, we need to multiply row 1 by \frac{1}{2}, that is to say:

\left[\begin{array}{cccc}1&\frac{1}{2} &-\frac{1}{2} &-4\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]

Hence, the correct answer is: Multiply row 1 by \frac{1}{2}.

What is the graph of the system y = −2x + 3 and 2x + 4y = 8? <br><br> Select one:
zhuklara [117]
 y = -2x + 3....slope = -2, y int = 3

2x + 4y = 8
4y = -2x + 8
y = -1/2x + 2....slope is -1/2, y int is 2

this is graph C

Find the midpoint of the segment with the following endpoints (4,6) and (1,3)
mrs_skeptik [129]

Answer:

The midpoint is (2.5,4.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2

(4+1)/2 = 5/2 = 2.5

To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2

(6+3)/2 = 9/2 = 4.5

The midpoint is (2.5,4.5)
