The sum of 3 numbers is 11. the sum of twice the first number, 5 times the second number, and 6 times the third number is 38. the difference between 5 times the first number and the second number is 26, find the three numbers

y=mx+b

step-by-step explanation:

m slope, b y-intercept

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

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
