If x is a positive integer, then the solution set of 4x+2< 14 is?

x = {1,2}

Step-by-step explanation:

Because...

4x+2<14

= 4x<12

X<3

♤ Therefor, the answe is {1,2}.

◇ Hopefully this helps:)

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
