.
    Cost of photos purchased online is $0.15 per photo. However there is a shipping cost of $2.70. This can also be modeled to be linear in number of photos as  .
.

Answer:  The graph becomes narrower
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k   where
- |a| represents the vertical stretch if |a| > 1, vertical shrink if |a| < 1
- (h. k) represents the vertex
A vertical stretch means the curve gets narrower.
A vertical shrink/compression means the curve gets wider.
 
        
             
        
        
        
Answer:

Here,  denotes the required number.
 denotes the required number.
Step-by-step explanation:
Let  denotes the required number that satisfies the following condition.
 denotes the required number that satisfies the following condition.
''seven times a number is less than or equal to a quantity that is 24 less than that same  number''
Seven times a number is equal to 
Quantity that is 24 less than that same  number is equal to 
Now find the inequality.
As seven times a number is less than or equal to a quantity that is 24 less than that same  number,
