A set of equation can be set up:
a=b+15
3(a+b)=345
where a is the faster and b is the slower bus.
substitute b+15 into the second equation, so 6b+45=345, and 6b=300, therefore b=50.
we can then figure out that a=65
Answer:
the vertex of this parabola is at (-6, 2).
Step-by-step explanation:
Compare the given y=-(x+6)² + 2 with the standard vertex form:
y = a(x - h)^2 + k. We see that
h must be -6 and k must be 2.
Thus the vertex of this parabola is at (-6, 2).
