The top row of matrix A (1, 2, 1) is multiplied with the first column of matrix B (1,0,-1) and the result is 1x1 + 2x0 + 1x -1 = 0 this is row 1 column 1 of the resultant matrix
The top row of matrix A (1,2,1) is multiplied with the second column of matrix B (-1, -1, 1) and the result is 1 x-1 + 2 x -1 + 1 x 1 = -2 , this is row 1 column 2 of the resultant matrix
Repeat with the second row of matrix A (-1,-1.-2) x (1,0,-1) = 1 this is row 2 column 1 of the resultant matrix, multiply the second row of A (-1,-1,-2) x (-1,-1,1) = 0, this is row 2 column 2 of the resultant
Repeat with the third row of matrix A( -1,1,-2) x (1,0, -1) = 1, this is row 3 column 1 of the resultant
the third row of A (-1,1,-2) x( -1,-1,1) = -2, this is row 3 column 2 of the resultant matrix
Matrix AB ( 0,-2/1,0/1,-2)
Answer:
36 pounds granola in a year
Step-by-step explanation:
Well there are 12 months a year.
She eats 48 ounce every month.
48 ounce = 3 pounds
3 pounds * 12 months = 36 pounds a year
//she sure does like granola o.o
Since it is an isosceles triangle, the two angles across from the two equal sides must be equal. Therefore, 8y-7=73 so 8y=80 so y=10.
So, each of those to base angles is 73°. If you add them together those two angles equal 146°. Since there are 180° in a triangle, 180-146 equals 34 degrees.
So 6x+4=34 so 6x=30 so x=5.

Step-by-step explanation:
x greater than 9 AND x smaller than 9
x smaller than than 9 OR x greater than 9
x greater than or equal to 9 AND x smaller than or equal to 9
x smaller than or equal to 9 OR x greater than or equal to 9
I dunno if this is what you asked^^
