How many solutions does this system of equations have?

3x+2y =6

-4x+5y=15      a. none   b. exactly one   c. exactly two   d. infinitely many

 B. exactly one

Step-by-step explanation:

The given system of linear equations :

When we find the ratio of the coefficients of the corresponding variable x and y term , we get

 ,

But

⇒ System is representing two intersection lines .  [if ratio of the coefficients of the corresponding variable x and y term is not equal then they represent intersecting lines.]

⇒System has one unique solution.   [Intersecting lines have one solution on plane.]

Hence, the correct answer is B. exactly one

i will pick c put check it over to be sure

step-by-step explanation:

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 !
