Answer:
The constant of variation is 5
Step-by-step explanation:
We know direct variation is of the form
y = kx
We know y =25 and x=5
25 = k*5
Divide each side by 5
25/5 = 5k/5
5 = k
Take the augmented matrix,
Swap the row 1 and row 2:
Add -2(row 1) to row 2, and -1(row 1) to row 3:
Add -1(row 2) to row 3:
Multiply through row 3 by 1/9:
Add 5(row 3) to row 2:
Multiply through row 2 by -1/3:
Add -2(row 2) and -1(row 3) to row 1:
So we have .
