Answer:
2nd option
Step-by-step explanation:
Using the identities
tan²θ + 1 = sec²θ
cotθ = 
Given
secθ = - 
, then
tan²θ + 1 = (- )² = 
( subtract 1 from both sides )
tan²θ = 
( take the square root of both sides )
Since 
< θ < π and tanθ < 0 , then
tanθ = - 
Then
cotθ = 
= - 
10 kilometers away i think, im not sure lol
Answer: 4.
Step-by-step explanation: In this case it is easier to imagine it on the number line: the y coordinates are the same, so the distance is only in x direction. On the positive side it is 2 2/3 to zero and on the negative, 1 1/3 to zero. Total is 1 1/3 + 2 2/3 = 4. Or the proper writing: 2 2/3 - (-1 1/3) = 4
Distributive Property.
You would get 3x-4
Answer:
x=−y+19
Step-by-step explanation:
(x+5)(2)+(y−3)(2)=42
Step 1: Add -2y to both sides.
2x+2y+4+−2y=42+−2y
2x+4=−2y+42
Step 2: Add -4 to both sides.
2x+4+−4=−2y+42+−4
2x=−2y+38
Step 3: Divide both sides by 2.
2x
2
=
−2y+38
2
x=−y+19
