Can someone help me with this?

1 is 1/2

Step-by-step explanation:

rise is over run then you simplify.

first you have to find the interception point. the place when the x and y meet it can be any point as long as it's in a corner of a square.

then you do rise over run.

if the live is going up then it's going to be a rise and a run. depending on left and right can determine the positive or negitve.

up is positive, down is negitve, right is positive, and left is negitve.

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!
