The total amount charged for each work can be expressed by the equation : 100 + 5x
Fixed charged per work = 100.00
Charge per page printed = 5.00
<u>Let the number pages printed be represented as x :</u> 
Total amount charged for n pages can be related thus : 
Fixed charge per work + (cost per page × number of pages) 
100 + 5x 
Therefore, the total amount charged can be expressed with the equation 100 + 5x

Answer:
y - 12 = 9(x - 4)
Step-by-step explanation:
The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph.  Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into  y - k = a(x - h)^2, obtaining
21 - 12 = a(5 - 4), or  9 = a.  With a known, we can write the desired equation:
y - 12 = 9(x - 4)
 
        
             
        
        
        
Answer:
a = 9
Step-by-step explanation:
 2(a + 7) = 5a - 13
We want to bring a to one side, I will choose to bring it to the right
First, expand the bracket by multiplying 2 with a + 7
2a + 14 = 5a - 13
Bring the -13 to the left by adding 13 to both sides
2a + 14 + 13 = 5a - 13 + 13
Simplify
2a + 27 = 5a 
Bring the 2a to the right by subtracting 2a from both sides 
2a - 2a + 27 = 5a - 2a
Simplify
27 = 5a - 2a
27 = 3a
Bring the 3 to the left by dividing both sides by 3
27÷3 = a
Simplify
a = 9
