First of all we know the
Absolute Value Function that is:

This is called the
Parent Function <em>of the Absolute Value Function.</em>
From the equation:

The term:

means that the the Parent Function is <em>shifted</em>
two units <em>to the left</em>.
On the other hand, the term:

means that the function

is <em>shifted</em>
three units <em>downward. </em>So the result is the graph shown below
Given:
Point( 7, 5)
x = 7 and y=5
slope(m) = 1
We need to first find the intercept.
Substitute x=7, y=5 and m=1 into y=mx + b and solve for intercept(b)
5 = 1(7) + b
5 = 7 + b
5 - 7 = b
-2 = b
Now, form the equation by substituting the value of the slope and intercept into y=mx + b
y = x - 2
To hundred three hundred and five
12x-4320=120
12x=120+4320
12x=4440
x=370
Answer:
$1.15
Step-by-step explanation:
add the cost of all of the items: 1 + 3.50 + 3.50 + 1 = 9
multiply 9 by the given discount: 9 x 0.15 = 1.35
you get 1.15, this is the dollar price of the discount
