y=1.2x-5
Step-by-step explanation:
Parallel lines are equal lines that never intersect or touch each other.
When a problem gives you information about the line being parallel to another, you'll know the slope of the line is going to be the same.

Answer: Probability is 0.00205 = 0.205%
Step-by-step explanation: P(rain) = 0.71, P(no rain) = 0.29.
P(no rain in 5 days)= 0.29·0.29·0.29·0.29·0.29= 0.00205
Recall the sum identity for cosine:
cos(a + b) = cos(a) cos(b) - sin(a) sin(b)
so that
cos(a + b) = 12/13 cos(a) - 8/17 sin(b)
Since both a and b terminate in the first quadrant, we know that both cos(a) and sin(b) are positive. Then using the Pythagorean identity,
cos²(a) + sin²(a) = 1 ⇒ cos(a) = √(1 - sin²(a)) = 15/17
cos²(b) + sin²(b) = 1 ⇒ sin(b) = √(1 - cos²(b)) = 5/13
Then
cos(a + b) = 12/13 • 15/17 - 8/17 • 5/13 = 140/221
