Use the information given to answer the question A pack of crayons costs 1.25. If z packs of crayons are purchased, the total price, P, can be represented by the relation P = 1.252.
Does P 1.252 represent a function, and why?
The relation is a function because there is exactly 1 value of P for every value of 1.
The relation is a function because there is exactly 1.25 value of P for every value of z.
The relation is not a function because there is exactly 1.25 value of P for every value of 2.
The relation is not a function because there is not exactly 1 value of P for every value of z.

the correct answer is c

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.
