The first thing that shoyuld be noted is that you have linear functions here : straight lines in your graph
Answer:
option 3)
14% approx
Step-by-step explanation:
Given data
Initial= $18.00
final =$20.50
% increase= final - initial/initia *100
% increase= 20.50-18.0/18*100
% increase=2.5/18*100
% increase=0.138*100
% increase=13.8%
Hence the increase is 13.8%
=14% approx
Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
Yes that is correctttttttttttttttt
