6) in business, a break-even is the point (x, y) at which the graphs of the revenue and cost intersect. For
one manufacturing company, the revenue from producing x items is given by the function y = 4x + 24
and the cost for producing xitems is given by y = -x2 + 15x + 6. Find all break even points.
Why wouldn’t it be (2,32) and (9,60)

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

i think the answer is b x = 1, y = 35/2

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
