A suit is on sale for $154. If the original price of the suit was $440, what percent was discounted for the sale?

9966 [12]

The dollar amount of the discount is 440 - 154 = $286.
Therefore the percentage discount for the sale is given by:
$\frac{286}{440}\times100=65\ percent$

Place the quadratic y=2x^2+24x+79 into vertex form by using the method of completing the square and then state the coordinates o

Answer:

$y=2(x+6)^2+7$

$(-6,7)$

Step-by-step explanation:

$y=2x^2+24x+79$

Completing the square is a process of converting a quadratic equation in standard form into vertex form.

The first step in completing the square is grouping the quadratic and linear terms of the quadratic equation.

$y=(2x^2+24x)+79$

Factor out the coefficient of the quadratic term,

$y=2(x^2+12x)+79$

Now complete the square, add a term to make the grouped part of the equation a complete square, then balance the equation.

$y=2(x^2+12x+36-36)+79$

Simplify,

$y=2(x^2+12x+36)+79+(2)(-36)$

$y=2(x+6)^2+79-72$

$y=2(x+6)^2+7$

The x-coordinate of the vertex of the equation is equal to (-1) times the numerical part of the quadratic term, and the y-coordinate is equal to the constant.

$(-6,7)$
