Answer:
(f - g)(x) = 9x + 1
Step-by-step explanation:
Step 1: Write out functions
f(x) = 3x + 10x = 13x
g(x) = 4x - 1
Step 2: Find (f - g)(x)
(f - g)(x) = 13x - (4x - 1)
(f - g)(x) = 13x - 4x + 1
(f - g)(x) = 9x + 1
 
        
             
        
        
        
Answer:
(a)
A single avocado costs $1
A single tomato costs $0.5
(b)
An avocado costs twice as much as a tomato
<em></em>
Step-by-step explanation:
Represent the tomatoes with T and the avocados with A.
So, we have:
 --- (1)
 --- (1)
 --- (2)
 --- (2)
Solving (a): The price of each
Multiply (1) by 1.5

 --- (3)
 --- (3)
Subtract (3) from (2)




Divide both sides by 2

Substitute 1 for A in (1)



Make 4T the subject


Divide both sides by 4


Solving (b): Analysis
In (a), we have:


<em>We can say that an avocado costs twice as much as a tomato</em>
 
        
             
        
        
        
The formula is A = Pe^(rt)where A = amount in the account after a specified period of timeP = principlee = a constant value (similar to using pi in a formula)r = rate (change to a decimal)t = time (in years unless otherwise specified)
A = 5500e^(.08*6)A = $8888.41Always round money to two decimal places unless told otherwise.
