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:
m=-17/4
Step-by-step explanation:
Slope is equal to m= y-y/x-x
Therefore it will be 9-(-8)/-4-0
(x,y)
if x repeats with a differnt y then it is not a function
A. none of them repeat, it's a function
B. none of them repeat, it's a function
both of them are functions
Answer:
$3
Step-by-step explanation:
When doing estimation, you would want the estimated amount to be rounded off to a number that can be divisible by the question, which in this case is 4. Thus, I will be rounding $11.87 to $12.
11.87 ≈ 12
Amount each friend will pay ≈ 12÷4
= 3
Use Pythagorean's Theorem to find the length of x.
so
and
. We can simplify that radicand down into a perfect square times a prime number, and that is
. 4 is a perfect square that can be pulled out as a 2, so the length of x is
, the choice on the top right.
