The system of equation, if a b are arbitrary numbers x+2y-3z- a 2x+4y-6z 2a+2 has (a) no solutions regardless of values of a and b (b) infinitely many solutions regardless of values of a and b (c) a unique solution if a b-0 d) a unique solution regardless of values of a and b

(A) No solutions regardless of values of a and b.

Step-by-step explanation:

Asumming that the system of equations is , the corresponding augmented matrix of the system is .

If two time the row 1 is subtracted to row 1, we get the following matrix

.

Then the system has no solutions regardless of values of a and b.

i think it is 18

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 !
