My best answer will be 12
Step-by-step explanation:
sinx = a/b
tanx= a/c
cosx= c/b
Answer:
20!
Step-by-step explanation:
Answer: D
Step-by-step explanation:
The key to finding the line perpendicular to the one given is teh slope. The slope is the opposite reciprocal of the original line.
m=3
perpendicular m=-1/3
Now that we know the slope, we can see which of our answer choices have -1/3 as the slope. We can see D is the only option that has -1/3 for slope.
This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
