Answer:
The variable c represents the domain as it is the independent variable.
The domain of the function F(c) is given by c ≥ 0.
So, only positive values for the input make sense.
The upper limit of the domain is +∞ and lower limit is 0.
It is not possible for the team to earn $50.50 as it will be only multiple of 2.
Step-by-step explanation:
If F(c) represents the earning of a volleyball team from selling c cupcakes and each cupcake costs $2 each, then the equation that models the situation is
F(c) = 2c ..... (1)

Answer:
Not sure if you mean 2x+y=-4 or 2x+y=4
either way put it in y=mx + b form (slope intercept)
Step-by-step explanation:
so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis
so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis
Answer:

Step-by-step explanation:
Given
Equation: 
Required
Determine the equation of Point: (5,4)
First, we need to determine the slope of 
The general form of an equation is 
Where m represents the slope;
Hence; 
Since the equation and the point are parallel. then they have the same slope (m).

Next, is to determine the equation of the point, using the following formula:

Where

So, the equation becomes

Cross Multiply

Open Bracket

Make y the subject of formula


Hence, the equation is

Step-by-step explanation:
Given the equation of parabola

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point 
This parabole goes downwards in y-direction (the leading coefficient -5 is negative)
<u>The axis of symmetry</u> of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Thus, the equation of the axis of symmetry is
