Answer:
B. x ≥ -3
Step-by-step explanation:
-4 x - 10 ≤ 2
add ten by both sides
-4x≤12
divide -4 by both sides
x ≤ -3
BUT because you divded  you have to switch the sign so 
x ≥ -3
 
        
                    
             
        
        
        
Answer:
$542
Step-by-step explanation:
we know that
The equation of a exponential decay function is given by

where
y is the value of the lawnmower
x is the time in years
a is the initial value
r is the rate of change
we have

substitute


For x=5 years

 
        
             
        
        
        
Answer:
No
Step-by-step explanation:
While these values are close, they are not equal, so I know the original fractions cannot be proportional to each other. So my answer is: The fractions are not
 
        
             
        
        
        
60. 
let x be the number you're trying to solve.
(x/100)25 = 15
x/4 = 15
x = 15(4)
x = 60
