Answer:
a =13/5
Step-by-step explanation:
f(x) = 6x − 5
f(5a) = 6*5a − 5=73
        30a -5 = 73
Add 5 to each side
     30a -5+5 = 73+5
       30a =78
Divide  by 30
30a/30 = 78/30
a =13/5
 
        
                    
             
        
        
        
C. Hummingbirds are hovering over the geraniums while caterpillars munched leaves.
This is because the tense of the hummingbirds is in the "ing" form, while the tense of the caterpillars is in past tense, or the "ed" form.  Because these tenses do not agree, it is an inappropriate shift in verb tense.
        
             
        
        
        
Answer:
JRQ = 56
Step-by-step explanation:
SRQ - SRJ = JRQ
166 - 110 = 56
 
        
             
        
        
        
Well combine:
2x + 3x + x + 60 = 180
combine like terms:
6x + 60 =180
 then move the 60:
6x = -120
 now divide both sides by 6:
x= -20
 i hope this helped! :)
        
                    
             
        
        
        
Answer:
The answer is Tonya's phone had the greater initial trade-in value. 
Leo's phone decreases at an average rate slower than the trade in value of Tonya's phone.
Step-by-step explanation:
Given
Tonya

Leo




Solving (a): The phone with greater initial value
The initial value is when x = 0. So, we have:




From Leo's table

By comparison;

i.e.

<em>So: Tonya's had the greater initial trade-in value</em>
Solving (b): The phone with lesser rate
An exponential function is:

Where:

For Tonya

For Leo, we have:


So, the equation becomes:

 and
 and 
Solving  , we have:
, we have:



 becomes
 becomes

Divide both sides by 480

Take square roots

 -- Leo's rate
 -- Leo's rate
By comparison; Leo's rate is slower i.e. 0.87 < 0.88
