You earn $10 per hour working as a manager at a grocery store. You are required to work at the grocery store at least 8 hours per week. You also teach music lessons for $15 per hour. You need to earn at least $120 per week, but you do not want to work more than 20 hours per week.

A. Write a system of linear inequalities that represent the situation.
B. identity and interpret a solution of the system.
C. Use a graph to determine whether you can work 8 hours at the grocery store and teach 1 hour of music lessons.

I would chose A

Step-by-step explanation: 80 + 15h ≥ 120

g + m ≤ 20

80 being the amount you make at the grocery store after working  8 hours and 15 being the amount you make teaching music lessons and h representing the number of hours you teach

then g representing the number of hours you work at the grocery store and m representing the number of hours you working teaching music lessons

im sorry that was kind of all over the place  

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
