Answer:
{6,7,8,9,10}
Step-by-step explanation:
Solve the inequality using inverse operations.

This solution means values equal to or larger than 6 from the set are solutions. This means 6, 7, 8, 9, and 10 are the solution set.
The vertex of f(x)=-x2+4x-8 is (2, -4)
Answer:
Three
Step-by-step explanation:
The perfect cubes between 2 to 200 are

Hence, there are only three perfect cubes 27, 64 and 125 between 2 to 200.
4 because 2 shoes for each stock pair and 4 × 2 = 8
Answer:
Step-by-step explanation:
Vertex form is accomplished by completing the square on the quadratic. Do this by first setting the parabola equal to 0 then moving the constant over to the other side:

Now take half the linear term, square it, and add it to both sides. Our linear term is 6. Half of 6 is 3, and 3 squared is 9:

The reason we do this is to create a perfect square binomial on the left:
(obviously the 0 results from the addition of 9 and -9). Move the 0 back over to the other side and set the quadratic back equal to y:

This gives you a vertex of (-3, 0), which is a minimum value, since the parabola opens upwards.
