Let f=number of flowers in a vase, then:
5f-16=24 add 16 to both sides
5f=40 divide both sides by 5
f=8
So there were 8 flowers per vase in the beginning.
Answer:
x2-12x+3
Step-by-step explanation:
=x(x-3)-9(x-3)
=x2-3x-9x+3
=x2-12x+3
When the graph rises one square for a run of one square, the slope is 2 km/(0.5 h) = 4 km/h. When the graph rises half that fast, the slope is 2 km/h. When the graph is horizontal, the slope is 0. The slope of the distance vs time curve is the speed.
- S = 4 km/h, when 0 < t < 2 h
- S = 0, when 2 h ≤ t < 2.5 h
- S = 4 km/h, when 2.5 h ≤ t < 3 h
- S = 0, when 3h ≤ t < 4 h
- S = 2 km/h, when 4 h ≤ t < 5 h
