Write true or false for each inference. A. If a system of two inequalities has a solution, then their two half planes intersect.

B. If two half planes never intersect, then their system of inequalities has no solution.

C. If two half planes never intersect, then their boundary lines are parallel.

D. If the boundary lines of two half planes are parallel, then they have no solution area.

where is the image?

step-by-step explanation:

answer: i guess 105 degrees?

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
