Can someone help me with number 9 please? thanks
1 answer:
Each of the 223 million people put $10 back into circulation every year.
So every year, this much money goes into circulation, and this is how much that goes into circulation the first year.
This is how much that will be in circulation after 2 years.
This is how much that will be in circulation after 3 years.
So we can create the table:
![\sf\left[\begin{array}{cc}\sf Years&\sf Money&\sf 1&\sf 2,230,000,000\\\sf 2&\sf 4,460,000,000&\sf 3&\sf 6,690,000,000\end{array}\right]](https://tex.z-dn.net/?f=%20%5Csf%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D%5Csf%20Years%26%5Csf%20Money%26%5Csf%201%26%5Csf%202%2C230%2C000%2C000%5C%5C%5Csf%202%26%5Csf%204%2C460%2C000%2C000%26%5Csf%203%26%5Csf%206%2C690%2C000%2C000%5Cend%7Barray%7D%5Cright%5D%20)
So every year, this much money goes into circulation, and this is how much that goes into circulation the first year.
This is how much that will be in circulation after 2 years.
This is how much that will be in circulation after 3 years.
So we can create the table:

Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
<h3>a)</h3>we want to expand the following expression:
well to do so we consider distributive property thus distribute:
reduce fraction which yields:
simplify Parentheses:
in the expression there's a common factor of 4 therefore factor it out:
we conclude that the center of the circle is the point (-5, 0).
<h3>How to find the center of the circle equation?</h3>The equation of a circle with a center (a, b) and a radius R is given by:
Here we are given the equation:
Completing squares, we get:
Now we can add and subtract 25 to get:
Comparing that with the general circle equation, we conclude that the center of the circle is the point (-5, 0).
