What are the values of a, b, and c in the matrix addition below?

-14 =a

-9 = b

-12 = c

Step-by-step explanation:

In matrix addition we add the corresponding elements to make equations

-10 +-4 = a

-14 =a

3 + -12 = b

-9 = b

-9 + -3 = c

-12 = c

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
