Segment AB is on the line y − 9 = −4(x + 1), and segment CD is on the line y − 6 = one fourth(x − 3). Which statement proves the relationship of segments AB and CD? A: They are perpendicular because they have slopes that are opposite reciprocals of 4 and negative one fourth. B: They are parallel because they have the same slope of 4. C: They are perpendicular because they have slopes that are opposite reciprocals of −4 and one fourth. D:They are parallel because they have the same slope of negative one fourth.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

answer: the answer is simply nothing.

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
