Park Crest Middle School has a population of about 400 8th graders. Park Crest is one of the several middle schools in a state which has a total of 804,000 8th graders. Use power of ten to estimate about how many times greater the states population of 8th graders is compared to the number of 8th graders at Park Crest Middle School. (scientific notation)

806, 240-400= 805, 840

Answer= 8.05840 x 10^5

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
