What’s the answer to -3 + 47 = 5x + 103

x = - 11.8

Step-by-step explanation:

to solve the question

-3 + 47 = 5x + 103

collect the like terms or combine the like terms

-3 + 47 - 103 = 5x

44 - 103 = 5x

-59 = 5x

divide both sides by the coefficient of x which is 5

-59/5 = 5x/5

x = - 11.8

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
