Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.
ycow [4]

This  involves quite a lot of arithmetic to do manually.

The first thing you do is to make the first number in  row 2  = to 0.

This is done by R2 = -3/2 R1 + R2

so the matrix becomes

( 2        1          1)    ( -3 )

( 0    -13/2   3/2)   (1/2 )

(5       -1           2)  (-2)

Next step is to make  the 5 in row 5  = 0  

then  the -1  must become zero

You aim  for the form

( 1 0 0) (x)

(0 1 0) (y)

(0 0 1) ( z)

x , y and z will be the required solutions.

Can you help me with this question I rlly need it rn and please use the options it gives you thank you&lt;3

Answer:  Choice C

Closed filled in circle at -3; shading to the right.

========================================================

Explanation:

Follow the steps shown below to isolate x. Note that the inequality sign flips when we divide both sides by a negative number.

-4x+8 \le 20\\\\-4x \le 20-8\\\\-4x \le 12\\\\x \ge 12/(-4)\\\\x \ge -3\\\\

Here's another way to isolate x

-4x+8 \le 20\\\\8 \le 20+4x\\\\4x+20 \ge 8\\\\4x \ge 8-20\\\\4x \ge -12\\\\x \ge -12/4\\\\x \ge -3\\\\

The inequality sign flip happens much earlier when we go from the format of A \le B to B \ge A  (in step 3)

The graph of this will have a closed filled in circle at -3, then shading to the right to describe all values -3 or larger.

This is why we go for choice C.

Which line is parallel to the line that passes through the points (1,7) and (-3, 4)? A.y=-3/4x-5 B.y=3/4x+1 C.y=4/3x-8 D. y=11/4
mixer [17]

Answer:

The Line p

y= 3/4x+ 6.25

Step-by-step explanation:

The points given changed 4 right and 3 up, giving a slope of .75

plug this slope into (1,7) to get the y-intercept.  This shows the intercept at 6.25.
