Answer:
Step-by-step explanation:
The slope is 1/4 since y increases 1 when x increases by 4 (you divide deltaY by deltaX).
Then, to make it go through (0,-4) you subtract -4.
Answer:
13/24
Step-by-step explanation:
=3/8+1/6=9/24+4/24=(9+4)/24=13/24
Answer:
Step-by-step explanation:
Answer: Choice A) 4, 3, 5, 1, 2
=====================================================
Explanation:
Since tan(x) = sin(x)/cos(x) is a known and widely used trig identity, this must mean step 4 goes first.
The answer is between choice A and choice B.
The question is now: What is the correct second step?
It's either step 3 (choice A) or step 5 (choice B)
It turns out that step 3 is the correct statement after step 4. The sin(2x) breaks up into 2sin(x)cos(x), while the cos(2x) breaks up into cos^2(x)-sin^2(x). There are three different variations for the cos(2x) and this just happens to be one of them.
So we can rule out choice B and go with choice A as the final answer.
