1) m=-2
2) C) y=-3/4x -6
3) D) y=2/5x-2
I don't understand 4 nor 5. My apologies.
6) Parallel
Answer:
the correct answer is (20,-12)
Step-by-step explanation:
First, you have to give each a variable. In this case, the smaller number will be x and the larger number will be y.
Next, you need to make the equations. Your equations are:
y+3x=14
x+2=y
What you're solving for is y because the questions asks what the larger number is.
Then, substitute. It will be this after substituted:
x+2+3x=14
Combine like terms.
4x+2=14
Subtract by 2 on both sides.
4x=12
Divide by 4 on both sides.
x=3
^This what your smaller number is but you can easily find what y (the larger number) is. Substitute x into the other equation, which is basically adding 2 to 3.
y=5

The double angle identities are
Then
The second identity together with the Pythagorean identity, 
, gives us another equivalent expression:
so
42,000 split into 10 is 4,200
if you meant 4 of those then it would be 16,800
