Answer:
-5
Step-by-step explanation:
dₙ = -5 (1/2)n-1
the 3rd term in the sequence means n = 3
d₃ = -5(1/2)(3-1) = -5(1/2)(2) = -5
Solution:
we are given that
A student has some $1 and $5 bills in his wallet.
Let there x $1 bills and y number of $5 bills.
He has a total of 14 bills that are worth $34.
So we can write


Now solve these two equations together using substitution as follows

Hence there are 9 $1 bills and 5 bills are of $5.

<h3><u>Answer;</u></h3>
The correct answer<em> </em><em><u>is true</u></em>
<h3><u>Explanation;</u></h3>
- <u>Dilation</u> is a type of transformation which stretches and reduces the size of the original figure.
- A dilation has a center of dilation and a dilation scale factor. If the scale factor is less than one then the original size will shrink, and if the scale factor is greater than one then the figure will increase in size.
- Dilation transformation does not alter the shape of a figure but alters the size by making it bigger or smaller.
