You have a solid cube of Dell consider the cross sections that are formed when you slice into a cube as described draw each slice and describe the resulting cross-section see a slice that cuts across a corner through three sides of the cube

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

m∠a is 90°

m∠b is 40°

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

the answer is  

a.
