Answer: option 1.
Explanation:
feasible region is that region which is formed by the lines of constraints.
feasible region is shaded in the attached graph
inequalities becomes equalities to draw the graph
and lines will head towards the origin if constraint satisfied by putting x= 0, y=0
and on the contrary lines will move away from origin when condition of constraint does not satisfied.
Answer:
Lisa will not be able to feed both tanks the same amount of food.
Step-by-step explanation:
This question is incomplete, here is the complete question :
"Lisa pet shop has 2 fish tank . Tank A contains smaller fish who were fed 1 gram of food each per day. Tank B contains larger fish who are fed 2 gram each per day. If tank B contains 2/3 the number of fish Tank A contains,will Lisa ever feed both tanks the same amount of food."
Let the number of fish in tank A = f
Lisa fed 1 gram of food each per day = f × 1 = f
So,the number of fish in tank B =
Lisa fed 2 gram of food each per day =
If both the tanks are fed with same amount of food then
⇒ 3f = 4f
⇒ 3 = 4
But 3 ≠ 4
Therefore, Lisa will not be able to feed both tanks the same amount of food.
