Answer:
Option b
or 
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function 
x> 0 for all real numbers.
Then the equation:
has two cases
if 
(i)
if 
(ii)
We solve the case (i)
We solve the case (ii)
Then the solution is:
or
follow these steps:
1) y-4=7x^2
2) (y-4)/7 = x^2
so you must inverse x and y names:
Answer: C) 65 degrees
Step-by-step explanation: the next highest is 90, but that would have the arrows in the shape of an L, since its closer than that, its lower than 90, so its 65.
2x^4
13b-10
5y+10
5a^3
2b^2+8a
