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]

S is in between T and U. ST = x + 4 and SU = 2x. TU = 16. Find the value of x.

solniwko [45]

You know the total length ST and SU, so to find x you would write an equation. This would be: x+4+2x=16 Combine like terms: 3x+4=16 Subtract four from both sides: 3x=12 Divide both sides by three: x=4
