Can a matrix with dimensions of 2 X 4 be added to another matrix with dimensions of 2 X 5?
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
X-2 times x plus 4 divided by x squared - 4?
x-2(x)+4/x^2 -4=x-2x+4/x^2 -4=-x-4+4/x^2
What does 2 to the 6th power equal?
2^(6) = 64 2 x 2 x 2 x 2 x 2 x2 = 4 x 4 x 4 = 16 x 4 = 64
2 is cubed what is 4?
The question is unclear - but the information provided may help. 2 squared (which can be written 22) = 2 x 2 = 4 2 cubed (which can be written 23) = 2 x 2 x 2 = 8 4 squared = 42 = 4 x 4 = 16 4 cubed = 43 = 4 x 4 x 4 = 64
Solve 2x-3y4 and x 4y 3 by matrix method?
2x - 3y = 4 x + 4y = 3 Write the augmented matrix: 2 -3 4 1 4 3 Multiply the first row by 1/2: 1 -3/2 2 1 4 3 Subtract the second row from the first row: 1 - 3/2 2 0 -11/2 -1 Multiply the second row by -2/11: 1 -3/2 2 0 1 2/11 Multiply the second row by 3/2 and add it to the first row: 1 0 25/11 0 1 2/11 Thus x = 25/11 and y = 2/11 Check:
