Tanner is 3 years younger than his sister lexi the sum of the siblings ages is 33 how old are tanner and lexi

tanner is 15 and lexi is 18

Step-by-step explanation:

I subtracted 3 from 33 and divided by two. That gave me tanners number, then added 3 to 15, which is 18, and also lexis age.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

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
