Answer:
C
Step-by-step explanation:
integers are a number which is not fraction, a whole number such as -5, 65, -86, 25
rational number is a number that can be expressed as the quatient or fraction p/q of two integers, a numerator p and a non-zero denominator q.
exp = -3/7, 0.75, -0.1, 4/9
First of all, you can use
and the equation becomes
Now, from the known identity
we can half all the angles and we get
So, the equation has become
So, everything comes down to solve
The associated equation
has roots
So, we want one of the following
Solve for the associated angles and you're done
Answer:
a. y=5x-1
b. 2y=8-2x
y=8-2x/2
y=4-x
c. y=3x-3
