Answer: The correct option is (c). 
Step-by-step explanation: We are given to select the correct basic identity that we will use to verify the following:

We have

In order to verify the given trigonometric equation, we must have

Thus, the required identity that we will use is

Option (c) is CORRECT.
Answer:
y=x+2 (slope = 1, y intercept =2)
Step-by-step explanation:
A parallel line will have the same slope but different y-intercept.
Answer:
25? to be honest i really dont know :/
Step-by-step explanation:
um pemdas says 5x5 is 25 so 5+(25)-5/5 then you do -5/5 is -1 and thats 5+(25)-5 then you add 5 to 25 and thats 30 and minus 5 is 25
Distance=√(x2−x1)2+(y2−y1)2 Distance = x 2 - x 1 2 + y 2 - y 1 2. Substitute the actual values of the points into the distance formula. √((8)−(3))2+((−7)−(−5))2 8 - 3 2 + - 7 - - 5 2. Simplify.
I believe that the answer is C.
