\begin{aligned} -3x-4y& =4 -5x+y& =2 \end{aligned} −3x−4y −5x+y =4 =2 is (2,10)(2,10)left parenthesis, 2, comma, 10, right parenthesis a solution of the system? choose 1 choose 1 (choice a) a yes (choice b) b no

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

boxplot

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
