25x-10

Step-by-step explanation:

I only know 2, sorry. But you just have to combine like 9x plus 16x is 15x then you place the -10 after it hope it helps.

And please, please, give me branliest I know that I only answered one so I'm sorry. But please give me branliest.

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
