Guess who’s back! i need with this! this is my last question i don’t want to get it wrong. also, can you explain to me what it means : /

Hello!

To solve this equation let's replace the > sign for now and make the operation sign = so we can solve for it.

First, we will subtract 8 from both sides. Making it -x=6-8

We will then solve for the right side, giving us -x=-2

To solve for x, we need to divide each side by -1.

When we are doing this, we get the result of x=2.

When we go to rewrite this equation as an inequality, the operation sign will be the opposite of what it originally was

Giving us the answer of x < 2 !

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
