Write an equation of the line that has a slope -1/2 and passes through the point (-4,5)

The equation of the line is y = -1/2x + 3

Step-by-step explanation:

In order to find the equation of the line, we need to use point-slope form along with the given information. Then we can solve for y to get the equation.

y - y1 = m(x - x1)

y - 5 = -1/2(x + 4)

y - 5 = -1/2x - 2

y = -1/2x + 3

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
