y = 5/4x + 10

Step-by-step explanation:

First, we need to use point-slope form which is:

y - y₁ = m(x - x₁)

Now, we substitute the numbers:

y - 5 = 5/4(x - (-4))

y - 5 = 5/4(x + 4)

y - 5 = 5/4x + 5

y = 5/4x + 10

You can check by substituting the points into the equation:

5 = 5/4(-4) + 10

5 = -5 + 10

5 = 5

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
