The dimension of a matrix is the no of rows by the no of columns.
Here there are two rows and five column. So the dimensions of the matrix is 2 x 5
Answer:
Step-by-step explanation:
y = - 9
y^2 = (-9)^2 = 81
AND
z = 0.7
z^2 = (0.7)^2 = 0.49
Hope it helped
GRAPHING CONS
1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.
2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.
3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution
SUBSTITUTION CONS
1) Becomes tedious if a system has too many equations or variables
ELIMINATION PROS/CONS
1) basically same as substitution
