Answer:
[-8 1]
[ 0 4]
[ 6 3]
[ -3 -4]
Step-by-step explanation:
The given matrix is;
[-1 2]
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;
[-3 -4]
C
8 hot dogs
1.25p
p = amount raised last year
amount raised this year = p +(25% of p)
=1 p+0.25p
=p(1+0.25)
=1.25p
c is a correct answer you know
