Hi!
I believe this will answer your question the parent function of f(x) = 5x − 1 is 5, the parent function of g(x) = 3^x − 9 is 3^x ln (3), and g(x) − f(x) is -5f+g*3^x ln (3)
The price of each taco is $10.5
What is unitary method?
We can solve this question by unitary method.
The unitary method is a method of finding the value of one unit and then finding the value of the required number of units. While solving a problem it is important to recognize the units and values.
In this question, 10 tacos cost $105.
Let's represent the cost of 1 taco as
10 tacos =$ 105
1 taco = 
10
= 105
= 
= 10.5

Answer:
x=9
<A=23
<B= 69
Step-by-step explanation:
1. 2x+5+3(2x+5)=92 2. 2x+5+6x+15=92 3. 8x+20=92 4. 8x=72 5. x=9
<A= 2(9)+5=18+5=23
<B= 3(2(9)+5)=3(23)=69
