Anthony has a cup full of nickels and dimes that he would like to put in his savings account. When he takes the cup to the bank,
2 answers:
Answer:
Step-by-step explanation:
Let nickels be represented by = n
Let dimes be represented by = d
Total number of coins in the cup = 566
So, first equation becomes :
The total value of coins is = $43.80
So, second equation becomes :
The equations are not given to choose from, but these are the equations that form according to given situation.

Here are all the steps, and what they do:
STEP 1: HORIZONTAL TRANSLATION
We transform
The general transformation is
These transformations translate the graph horizontally, k units to the left if k>0, k units to the right if k<0.
In this case, k = -1, so we translate the original graph 1 unit to the right.
STEP 2: VERTICAL STRETCH
We transform
The general transformation is
These transformations stretch the graph vertically. The graph expands if |k|>1, while it shrinks if 0<|k|<1. If k is negative, we also reflect the graph with respect to the x axis.
In this case, k = 3, so we stretch the graph vertically by a factor 3.
STEP 3: VERTICAL TRANSLATION
We transform
The general transformation is
These transformations translate the graph vertically, k units up if k>0, k units down if k<0.
In this case, k = 4, so we translate the graph 4 units up.
So, we start from the original graph of and we:
- Translate it 1 unit to the right
- Stretch it vertically by a factor 3
- Translate it 4 units up
(the order is important!)
