How do I find the Axis of Symmetry for a parabola

soldier1979 [14.2K]

Answer:

Explanation given below.

Step-by-step explanation:

The first step is to put the parabola in the form $ax^2+bx+c$ , which is the standard form of a parabola

Note: a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term

The axis of symmetry divides the parabola symmetrically. The axis of symmetry has the equation $x=-\frac{b}{2a}$

Where a and b are the respective values shown above

So, that is how you get the axis of symmetry of any parabola.

Solve the inequality -2z-3<5. what is the value of z?

agasfer [191]

Hey there!

The answer to your question is z > -4

We can solve this like it is an equation, with one exception. When you divide or multiply by a negative number, in an inequality, you have to flip the inequality sign.

-2z - 3 < 5 add 3 to both sides

-2z < 8 divide both sides by -2, and flip the inequality sign

z > -4

Good luck! Hope it helps, and have a great day!

The cost C (in dollars) of producing x DVD players is represented by C = 4.5x2. How many DVD players are produced if the cost is

lisabon 2012 [21]

Given the following equation representing the cost of producing DVD Players:

$\text{ C = 4.5x}^2$

Let's determine the number of DVD players produced if the cost is $544.50

$\text{ C = 4.5x}^2$ $\text{ \$544.50 = 4.5x}^2$ $\text{ }\frac{\text{\$544.50}}{\text{ 4.5}}\text{ = }\frac{\text{4.5x}^2}{\text{ 4.5}}$ $\text{ 121 = x}^2$ $\text{ }\sqrt{\text{121}}\text{ = }\sqrt{\text{x}^2}$ $\text{ 11 = x}$

Therefore, it'll cost $544.50 to produce 11 DVD Players.

The answer is 11.
