Answer:
y ≥ 3x -1; x +3y ≤ 6
Step-by-step explanation:
Both lines are solid, so the only viable choices are those with "or equal to" in the comparison operators: the 2nd and 4th choices.
The line with a slope of +3 is shaded <u><em>above</em></u> the line, so that will correspond to the inequality ...
y ≥ 3x -1 . . . . . . . . . . found only in the 4th choice.
Answer:

Step-by-step explanation:
Given:

This can be written as 


Circumference=diamter times pi
diamter=2 times radius
circumference=radius times 2 times pi
circunference=135.648
aprox pi to 3.14
subsitute
135.648=radius times 2 times 3.14
135.648=radius times 6.28
divide both sides by 6.28
21.6=radius
aswe ris radous=21.6 units
Answer:
500 students
Step-by-step explanation:
subtract all of the smaller numbers from the big numbers for each school.
school A = +530
school B = +480
school C = +490
530 + 480 + 490 = 1500
1500 ÷ 3 = 500
