step-by-step explanation:

4+x=2y

y=5

4+x=10

x=6

i think its 14

step-by-step explanation:

jack is represented by j and meyer is m then j=4+2m

if we know meyer is 5 then

2×5+4

10+4

14

step-by-step explanation: he ehe heh step by the thy

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
