Answer:
This is a question you should know in trig.
You should search up how to solve for simple trig functions
The cos of 60 degrees is 1/2 just because you asked
For this case we have that by definition, the line equation of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the statement we have:

Thus, the equation is of the form:

We substitute the given point and find "b":

Finally, the equation is of the form:

Answer:

10% of the 50 were red.
10% * 50
(10/100) * 50
(1/10) * 50
= 5
5 were red.
The answer is p=-2 because you add 5 to -17 and you get-12 then you do 6/-12 and you get -2
I'm sorry I only know one of them
