Recall your d = rt, distance = rate * time.
now, let's say she lives "d" miles away, and so if Billy goes say at "r" mph fast to her house, he gets there in 1hr.
now, if he goes 20 mph slower, namely " r - 20 " mph, he gets there in 2 hours, same "d" miles.
Answer:
B
Step-by-step explanation:
A right angle
Answer: Choice A
y=2x+3; y=-1/3x+3
==================================================
Explanation:
The left portion of the blue curve is y = 2x+3 but it is only graphed when x < 0 (we could argue that but I'll set that aside for the other portion).
The right portion is the line y = -1/3x + 3 and it's only graphed when
So we could have this piecewise function
Or we could easily swap the "or equal to" portion to move to the first part instead like this
Either way, we're involving the equations mentioned in choice A
Answer:
2f+9
Step-by-step explanation:
hope this helps
They are NOT because supplementary angles add up to 180
