Answer:
angle Y = 90 degrees
Step-by-step explanation:
Since it is stated that angle x forms a straight line with the 50 and 50 degree angles, and that angle x is vertical to angle y, we can do 40+50+y=180 to find angle Y.
Answer:
5
Step-by-step explanation:
The function
is
- decreasing for all

- is increasing for all
![x\in (0,2]](https://tex.z-dn.net/?f=x%5Cin%20%280%2C2%5D)
(see attached diagram for details).
The maximum value of the function is at endpoints -3 or 2. find y(-3) and y(2):

So, the maximum value is 5.
Answer:
y=12x+10 or f(x)=12x+10
Step-by-step explanation:
If it costs $12 per month to rent as many movies as you want, then that can be represented as 12x
Since $10 is a flat fee and doesn't change, this gets added seperately to 12x
Thus, the final equation is y=12x+10 or f(x)=12x+10
Hope this helped!
