Write the sum using summation notation, assuming the suggested pattern continues.

-3 + 6 + 15 + 24 + ... + 132

summation of negative 27 times n from n equals 0 to infinity
summation of negative 27 times n from n equals 0 to 15
summation of the quantity negative 3 plus 9 n from n equals 0 to infinity
summation of the quantity negative 3 plus 9 n from n equals 0 to 15

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

2 2/3 hours duhh silly
