describe how do you know if two lines are parallel if all you knew were the equations of the two lines
2 answers:
Two lines are parallel if they intersect.
Answer:
Step-by-step explanation:
Put what you are given in the form of
y = mx + b
If both equations have the same m, the lines are parallel. For example
y = 4x + 10
y = 4x + 20
These two lines are parallel.
However
y = 8x + 40
y = 4x + 10 are not parallel even though it looks like m could be made the same by taking out 4 in each. Check them out on the graph below.

Answer:
tanθ = 3/4 p/b
using Pythagoras theorem
H² = P² + b²
H² = 3²+ 4²
H² = 25
H = 5
cosθ = B/H = 4/5

8 ft= ___ inches
1 ft= 12 inches
8 ft= 12 x 8 inches
8 ft=96 inches
She has 96 inches, but she needs 100 inches. So she needs 4 more inches of lumber.
Since both terms have the same variable to the same power, you can simply add the coefficients...
14x^7
The difference is 160
