Find the measures of ∠n and ∠o.

Hello there

3y+15=4y-3

3y-4y=-15-3

-1y=-18

y=18°

N=3•18+15=69

O=4•18-3=69

The right answer is the last one

:D

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
