Mat saw chickens and goats on a farm. He saw a total of 16 animals and can count 50 legs. Write a solve a system of equations to find how many chickens and how many goats were on the farm. Enter your answer as an ordered pair (x, y).

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

step-by-step explanation:

combine all like terms then its just a 2 step equation
