Give me a minute. I’m trying to solve
        
             
        
        
        
Answer:
-(4x + 7)/2 - (3x - 2)/2 = (-4x - 7 - 3x + 2)/2 = (-7x - 5)/2
 
        
             
        
        
        
Firstly, let's create a function of f(t) where t represents the time that has past, and f(t) represents the amount of rainwater. We know that when t=1, then f(t)=10, and t=2 then f(t)=15. So, let's take that and analyze it:
(1,10)
(2,15)
m = (15-10)/(2-1) = 5
y-intercept = 5
∴ f(t) = 5t+5
Now we just evaluate t for 10:
f(10) = (5*10)+5
f(10) = 55
        
             
        
        
        
There are 12 inches in a foot. When you convert 12 into millimeters, it becomes 304.8.
        
             
        
        
        
Answer:
The answer is... the first option... why equals negative x + 5 and y = x - 3
