Answer:
c+s < 12, 2c+4s >= 30.
Step-by-step explanation:
Known: at least 30 legs, less than 12 heads.
Each animal has one head, so if there are less than 12 heads, then c + s < 12.
Sheep have four legs and chickens have two legs, so if there are at least 30 legs, then # of chicken legs + # of sheep legs >= 30, ----> c(2) + s(4) >= 30, ----> 2c + 4s >= 30.
The graph attached models the problem is you set the x axis as "c" (# of chickens) and y axis as "s" (# of sheep).
