Answer:
4x +3y = 7; 1 ≤ x ≤ 9; 1 ≤ y ≤ 9
(x, y) = (1, 1)
Step-by-step explanation:
If you simply add the numbers, you have ...
(x+y) +(3x+2y) +8 +9 = 24
This simplifies to ...
4x +3y = 7
Perhaps the other "equations" in the "system of equations" are the constraint inequalities ...
The smallest possible value of both x and y is 1, which would satisfy this equation:
4·1 + 3·1 = 7
Using the expression (x+y) +(3x+2y) +8 +9 = 24, suitable values for x and y are 1 and 1.
_____
We have written one equation, which in this context only has one solution for the two variables. It seems likely that we need to know more about the game card in order to write a system of equations.
Answer:
Step-by-step explanation:
slope of line through (6,-1) and (11,2) = (-1 - 2)/(6 - 11) = 3/5
slope of line through (5,-7) and (8,-2) = (-7 - (-2))/(8 - 5) = -5/3
product of the slopes = -1, so the lines are perpendicular.
Answer:
AB: size 4 x 4
BA: size 2 x 2
Step-by-step explanation:
When we want to multiply two matrices, we need first to check if the number of columns of the first matrix is equal the number of rows of the second matrix. Then, the resulting matrix would have the number of rows equal the number of rows of the first matrix, and the number of columns equal the number of columns of the second matrix.
That is, if we have a matrix A with dimensions a x b and a matrix B with dimensions c x d, to calculate the product AB we must have b = c, and the resulting product would have dimensions a x d.
Finally, if A is 4 x 2 and B is 2 x 4, we would have:
AB = (4 x 2) (2 x 4)
2 = 2 -> product is possible.
Dimensions of the result: 4 x 4
BA = (2 x 4) (4 x 2)
4 = 4 -> product is possible.
Dimensions of the result: 2 x 2
