Answer:
B
Step-by-step explanation:
Parallel lines never touch. A is an intersecting line C is perpendicular and D is just a line.
Step 1: Isolate the variable term (the x and its coefficient (the number in front of it))
Step 2: Get the variable alone
and thats your answer :)
In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3. 16 is a perfect square and 10 is not a perfect square
r =
multiply both sides of the equation by r - 3
t(r - 3 ) = r ( distribute and collect terms in r together )
tr - 3t = r
tr - r = 3t ( factor out r )
r(t - 1 ) = 3t ( divide both sides by r - 1 )
r =
