X^2-18 = 3x
x^2 - 3x - 18 = 0
(x-6)(x+3) = 0
x = {-3,6}
So -3 is the answer
Expanded: 3x^2 + 17x +10
Simply: it’s already simplified
Answer:
120 coins our in her purse if the 2 dollar factor is made up of nickels
<em><u>Answer</u></em>
c. It divides the radius by 2.
<em>Explanation</em>
The general equation of a circle is
(x-h)² + (y-k)² = r²
Where (h, k) makes the coordinates of the circle and r the radius.
x² + y² = 25 For this equation,
center (0, 0)
Radius = √25 = 5
4x² + 4y² = 25 First simplify this equation
4x² + 4y² = 25 ⇒ x² + y² = 25/4
center (0, 0)
Radius = √(25/4) = 5/2
The radius has been divided by 2
Example of six ordered pairs with country names alongside their capitals are:
{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.
<h3>What are Ordered Pairs?</h3>
- Ordered pair can be described as a pair of objects or numbers in a particular order.
- In an ordered pair, the order of the objects or numbers are very important. For example, (a, b) is not the same as (b, a).
Therefore, example of six ordered pairs with country names alongside their capitals are:
{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.
