Answer:
x = 6
Step-by-step explanation:
y varies inversely as x
y = k × 1/x. {where k is a constant}
when y = 3, x = 8
Therefore 3 = k/8 and k is 24
y = 24/x
When y = 4,
4 = 24/x
4x = 24
(dividing both sides by 4)
x = 6
Answer:
We are looking for the amount of wax it will take to fill up that size candle mold to make that candle. That means that we are looking for the volume of wax, and the shape is a cylinder. The volume formula for a cylinder is
For us, that will look like this:
which translates to
V = 3.14(9)(5) which gives us a volume of 141.3 cubic inches. Rounding to the nearest cubic inch is simply 141 cubic inches of wax.

Answer:
I believe it is C) decreasing when x > -1
Step-by-step explanation:
If you plot all 3 points on a graph, you will notice that the parabola is facing downwards. This means that on the left side of the vertex, it is increasing (the y-value increases). On the right side of the vertex, it decreases (y-value decreases). Note that "decreasing" refers to the y values.
So, since the vertex's x-value is -1 (we know this from the point (-1, 2)), any x-value greater than -1 will be to the right of the vertex. For example, 0, 1, 2, 3, etc. are all greater x-values than -1, so they are all to the right of -1. Since they are on the right, that means the corresponding-values will be decreasing.
Therefore, when x > -1, the parabola is decreasing.
