Important answer quick doing test worth 30 points
Which set of three angles could represent the interior angles of a triangle?
190, 700, 91°
470, 120, 310
500, 200, 20°
250, 250, 100

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

i'm pretty sure the answer is a. decreases with increase in

i believe so, according to my "strange" way of figuring out weird math problems like this.
