On a coordinate plane, 2 quadrilaterals are shown. the first figure has points a (negative 2, 1), b (negative 4, 1), c (negative 4, 5), and d (negative 2, 4). figure 2 has points a prime (2, 1), b prime (4, 1), c prime (4, 5), and d prime (2, 4). what is the rule for the reflection? rx-axis(x, y) → (–x, y) ry-axis(x, y) → (–x, y) rx-axis(x, y) → (x, –y) ry-axis(x, y) → (x, –y

answer: -1

step-by-step explanation:

hi! i think the answer is 1/2 : )

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
