Answer:
-5x
Step-by-step explanation:
Answer:
The lowest point is -100 meters, or 100 meters down
Step-by-step explanation:
D(x)=1/36(x-60)^2-100
This equation is in vertex form
y = a(x-h)^2 +k where (h,k) is the vertex
Since a is positive, the parabola opens up
The vertex is the minimum, which means it will be the lowest point
The vertex is (60,-100)
The lowest point is -100 meters, or 100 meters down
Answer:
the answer is A
Step-by-step explanation:
-17 - (-7) = -24
a = -24
Answer:
12.5x-5(x-1)
Step-by-step explanation:
you can find the pattern easily
it simplifies as
12.5x-5x+5=7.5x+5
