Answer:
We want to write the cost equation for the company.
First, we know that:
It cost $20 per box.
There is a fixed cost of $2300.
Then the only variable will be the number of boxes that they make.
Where the number of boxes is the independent variable (the company can decide the number of boxes that they make) and the dependent variable will be the cost (the cost changes as the number of boxes change).
Then we can write the cost equation as:
C(x) = $20*x + $2300.
Where x is our variable, the number of boxes made by the company.

Answer:
Equation: x+3<12 Answer: x<9
Step-by-step explanation:
SO bascially what you do is you find the equation based on the wording (The sum of a number and three is less than twelve) and after you find the equation (which is x+3<12), you subtract 3 from both sides, getting x<9

Answer:
.
Step-by-step explanation:
Let
,
, and
be constants, and let
. The equation
represents a parabola in a plane with vertex at
.
For example, for
,
,
, and
.
A parabola is entirely above the
-axis only if this parabola opens upwards, with the vertex
above the
-axis.
The parabola opens upwards if and only if the leading coefficient is positive:
.
For the vertex
to be above the
-axis, the
-coordinate of that point,
, must be strictly positive. Thus,
.
Among the choices:
does not meet the requirements. Since
, this parabola would open downwards, not upwards as required.
does not meet the requirements. Since
and is negative, the vertex of this parabola would be below the
-axis.
meet both requirements:
and
.
(for which
) would touch the
-axis at its vertex.
