Answer:

[-8 1]

[ 0 4]

[ 6 3]

[ -3 -4]

Step-by-step explanation:

The given matrix is;

[-1 2]

[ 0 4]

[ 6 3]

[ -3 -4]

From the image given;

Row 1 is; (-1, 2)

Therefore, 2R1 = 2(-1, 2) = (-2, 4)

Row 3(R3) is; (6, 3)

Thus;

2R1 - R3 = (-2, 4) - (6, 3) = (-8, 1)

The new matrix after the transformation is;

[-8 1]

[ 0 4]

[ 6 3]

[-3 -4]

Airplane X left the airport, flying at a rate of 400 miles per hour. Airplane Y left 2 hours later, flying at a rate of 450 mile
sergij07 [2.7K]

Answer:   i think it will take 48 hours

Step-by-step explanation:

here's how to get 48 so basically 450-400-2= 48

now if you end up doing 400 - 450 then you will get -50 if you do 400-450-2 you will get a -52 <u><em>so you want to make sure you do the biggest number first and then do the smaller numbers to get 48</em></u> like 450 - 400 - 2 and then you will have 48

i hope this helps!
