Answer:
<h3>B. -84</h3>
Step-by-step explanation:
Taking the determinant of the matrices we will have;
= 4x(5y) - 2x(3y)
= 20xy - 6xy
= 14xy
Given x = -2 and y = 3
Determinant = 14(-2)(3)
Determinant = -28*3
Determinant = -84
It would be 3/5 because if you simplify it you would bet 3/5
Answer:
Step-by-step explanation:
You have to do total ratio
that will give you 20/15
Answer:
