The diagram shows the graph of y = 2x + c, where c is a constant find the value of k.

Step-by-step explanation:

The equation is a linear equation. By definition, the independent term on this equation (that is, the number that is not being multiplied by ) is the y-intercept, which is a fancy way of saying "the point where the line crosses the y-axis".

By looking at the equation, we know that our y-intercept is c. By looking at the graph, we can see that the y-intercept is -3. Therefore, and we get the complete version of our linear equation:

Now, looking at the graph we can see that the point lies on the line of the equation, which means that the point is a solution to our equation. All we have to do is replace and by the values of the given point (which are and , respectively), and then solve for :

And we are done!

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 !
