Answer:
Step-by-step explanation:
If the matrix is of 2 by 2 then we can find the determinant of the matrix.

Then (ad - bc ) gives you the determinant of the matrix.
For example,

= (2)(-2) - (1)(4)
= - 4 - 4
= -8
(2.34/ 7.89) times 100 = ˜29.65%
You didnt list any graph?? Can you add it please :)
S=Years Susanna has played the piano
p=Years Patrick has played the piano
The expression for this question would be s(2)+4=p
Hope this helps! :)
