if polygon mast with coordinates m(-3,-1), a(-3,2),s (-1,3) and t (1,1) is reflected across x=-3, then which of the following coordinates represent the vertices of the polygon man's'? select all that apply
!

(-3,-1)

(-7,1)

(-3,2)

(1,1)

(-1,3)

(3,-1)

(-5,3)

The correct choices are (-3,-1), (-3,2), (-5,3) and (-7,1)

Step-by-step explanation:

Given that MAST with coordinates M(-3,-1), A(-3,2),S (-1,3) and T(1,1).

The mapping for reflection across the line is

The coordinates of M'A'S'T'.

M'(2(-3)--3,-1), A'(2(-3)--3,2),S' (2(-3)--1,3) and T'(2(-3)-1,1)

M'(-6+3,-1), A'(-6+3,2),S' (-6+1,3) and T'(-6-1,1)

M'(-3,-1), A'(-3,2),S' (-5,3) and T'(-7,1)

the first dot plot best represents the data

plzplzplzplz mark brainliest and have a good day

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
