Consider the system of inequalities

1. Plot all lines that are determined by equalities (see attached diagram)

2. Determine which bounded part of the plane you should select:
means that you should take points with y-coordinates greater than or equal to 2 (top part of the coordinate plane that was formed by the red line);
means that you should take points with x-coordinates less than or equal to 6 (left part of the coordinate plane that was formed by the blue line);- for
you can check where the origin is placed. Since
, the origin belongs to the needed part and you have to take the right part of the coordinate plane that was formed by green line. - for
you can check where the origin is placed. Since
, the origin belongs to the needed part and you have to take the bottom part of the coordinate plane that was formed by orange line.
3. According to the previous explanations, the shaded region is as in A diagram.
Answer: correct choice is A.
The four sides to create the square
Answer:
r ≥ -9
Step-by-step explanation:

A.) The clerk has - 16 oranges 20 apples 24 pears
he needs to put all three fruits into baskets without any leftover fruits
each basket should have equal amounts of each fruit
so to find the largest number of baskets he can make we have to find the highest common factor for 16,20 and 24
so lets find the factors for each of these
16 - 1,2,4,8,16
20 - 1,2,4,5,10,20
24 - 1,2,3,4,6,8,12,24
from the given factors the common factors for all three are 1,2 and 4
from these the highest factor is 4
therefore the largest number of baskets he can make are 4
in each basket there will be
4 oranges 5 apples 8 pears
answer is 4 baskets
