Answer:

The zeros of a quadratic function are the solutions of the related quadratic equation. If the graph of a quadratic function crosses the x-axis, there will be two real number solutions. If the graph of a quadratic function just touches the x-axis, there will be one unique real number, or double root, solution. If the graph of a quadratic function does not cross the x-axis, there will be no real number solution.

The equation for a quadratic is as follows:
y = ax^2+bx+c

The first variable “a” determines whether the parabola opens up or down
The squared allows the equation to look like the parabola swoop when graphed.
The c term is the constant term

What is the area of this polygon? Enter your answer in the box. units²

Gemiola [76]

Answer:

The area of the polygon is $39\:units^2$

Step-by-step explanation:

Sketch the polygon to obtain the figure in the attachment.

The polygon can then be divided into a rectangle and a triangle.

The area of the polygon

$=|VE|\times |DE|+\frac{1}{2}\times |DE|\times |AM|$

We use the absolute value method to find the lengths

$=|3--2|\times |3--3|+\frac{1}{2}\times|3--3|\times |5-2|$

$=5\times 6+\frac{1}{2}\times 6\times 2$

$=30+9$

$=39\:units^2$

Please help me with this question

MrMuchimi

Answer:

x = 9

Step-by-step explanation:

when two lines intersect, it creates four angles. vertical angles are the angles that are opposite to each other. in the attached image, 1 & 3 are vertical angle pairs, and so are 2 & 4.

since vertical angles are always congruent, 3x - 8 is equal to 2x + 1

3x - 8 = 2x + 1

add 8 to each side

3x = 2x + 9

subtract 2x from each side

x = 9

check your answer:

3x - 8 = 2x + 1

3(9) - 8 = 2(9) + 1

27 - 8 = 18 + 1

19 = 19

An item is regularly priced at $75 It is now priced at a discount of 60% off the regular price. What is the price now?

mel-nik [20]

Answer:

Price is $ 30

Step-by-step explanation:

Regular price = $75

Discount = 60%

First we find the 60% of 75

( 75 × 60 ) ÷ 100 = 45

Now this answer with regular price

75 - 45 = 30
