X+9-3≤14
Add 3 to the other side. (do the inverse of subtraction)
x+9≤17
Subtract 9 on both sides. (the inverse of addition)
x≤8 
I hope this helps!

Answer:
   8.6
Step-by-step explanation:
The growth factor per year is 1.012, so in 500 years is ...
   1.012^500
The number of doublings is the solution to ...
   2^n = 1.012^500
Taking logarithms, we have ...
   n·log(2) = 500·log(1.012)
   n = 500·log(1.012)/log(2) ≈ 8.6046
About 8.6 doublings will take place in 500 years.
 
        
             
        
        
        
Answer:
Domain :  0 ≤ t ≤ 3
Range :   -4 ≤ d ≤ 0
Step-by-step explanation:
The graph attached models the depth of submarine as a function of time.
Points on x-axis represent the time and points on y-axis represent increase in height of the submarine.
Domain of a function is represented by the points on x-axis.
Therefore, Domain :  0 ≤ t ≤ 3
Range of function is represented by te points on y-axis.
Therefore, Range :   -4 ≤ d ≤ 0
 
        
             
        
        
        
Answer:
<h2>y = 4x + 4</h2>
Step-by-step explanation:
The slope-intercept form:

m - slope
b - y-intercept
Parallel lines have the same slope.
We have y = 4x + 2 → m = 4.
The slope of parallel line is m = 4 and the y-intercept b = 4.
Therefore we have the equation of a line:
