Which statements are true? Select three options. The line x = 0 is perpendicular to the line y = –3. All lines that are parallel to the y-axis are vertical lines. All lines that are perpendicular to the x-axis have a slope of 0. The equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. The equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1 answer quickly as possible please and thanks

the answer to this question is in the pic

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

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
