Please help me with this problem

Answer and Step-by-step explanation:

I will try the best I can :3

if she started with 6, the first point you would put is (0,6)

this is how the equation would look:

y=___+6

(Tip: the number on the right is the y-intercept and the one on the left is the slope)

Now to find the slope: m=

y-y / x-x

Let’s use points (0,6) and points (2,8)

Rewrite to find slope: 8-6 / 2-0              =                 2/2 or 1

Now the equation should be:

y=1x+6

(p: you can also use Desmond graphing calculator ^^)

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
