Write an inequality to match the values shown on the number line.

X<4

Step-by-step explanation:

if the symbol is (≥ or ≤) then you fill in the dot, but  if the symbol is (> or <) then you do not fill in the dot.    

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

the correct answer is $7.38
