What are the first four terms of the sequence shown below? an = n^3 + ^2 a. 1, 2, 3, 4 b. 1, 12, 15, 20 c. 2, 12, 36, 80 d. 5, 10, 15, 18

   = 1 + 1

    = 2

   = 8 + 4

   = 12

   = 27 + 9

   = 36

   = 64 + 16

   = 80

step-by-step explanation:

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
