Answer:
C
Step-by-step explanation:
Both lines start and end on x = 3
The lower line has a positive slope and a y- intercept of - 2
The lower line has an open circle at it's endpoint indicating it cannot equal 3
x - 2 for x < 3
The upper line has a positive slope and a y- intercept of - 1, if we project the line. The line has a closed circle at it's start indicating it can equal 3, thus
x - 1 for x ≥ 3
Hence
x - 1 if x ≥ 3
x - 2 if x < 3 → C

Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
