Use differences to find a pattern in the sequence. 6,16,31,52,80,116,161 Assuming that the pattern continues, the eighth term should be?

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

56 44 2 4

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
