What is one and one so easy if you answer it correctly I will mark you brainiest

one and one? you mean two? or 1x1 is 1 1 divided by 1 is 1 and 1 minus 1 is 0

Step-by-step explanation:

i dont understand do you mean 1x1 1+1 1divided by 1

2

Step-by-step explanation:

as you described it appears to be addition

step-by-step explanation:

b and 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
