The matrix r=12/4 represents the length of 12 in. and the width of 4 in. of a rectangle. if matrix multiplication is used to double the length and width of the rectangle which represents the result of the matrix multiplication

Hence, in matrix from it could be written as:

R'=24/8=[24,8]

Step-by-step explanation:

It is given that:

The matrix R=12/4 i.e. R=[12,4] represents the length of 12 in. And the width of 4 in. of a rectangle.

If matrix multiplication is used to double the length and width of the rectangle.

i.e. the length of rectangle will get doubled so that the length will be=12×2=24 inches.

and similarly the width of the rectangle will get doubled and hence width of rectangle will be=4×2=8 inches.

Hence, in matrix from it could be written as:

R'=24/8=[24,8]

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
