Answer:
The trip lasted 9 days.
Step-by-step explanation:
Answer:
2x+3x=150 ( sum of opposite interior angle of triangle is equal to the exterior angle)
5x=150
x=150/5
x=30
Question 1.
First solve for slope:

Point-slope formula is:

where m = slope.
Plug in values for PS form:

So the answer is Choice 2.
Question 2.
Choice D.
Points given: (-10, -7) and (3, -7)
Both y -intercepts are equivalent to -7
Question 3.
Choice A.
Points given: (2, 4) and (2, -7)
Both x - intercepts are equivalent to 2
The lowest common multiple of 2 and 7 is 14, so 14 days will pass before he does both chores again.
9 is the answer negatives cancel out creating positve
