x(t) = 20t
y(t) = 40t - 5t^2
Since we are only interested in comparing the two at time t = 5 seconds, we plug in 5 everywhere we see the variable t and then compare x and y
x(5) = 20(5) becomes x(5) = 100
y(5) = 40(5) - 5(5)^2 becomes y(5) = 200 - 125 and then y(5) = 75
The ratio of y to x can be expressed as: y/x, so we can say the ratio is equal to 75/100 or 0.75
Answer: 0.75
 
        
             
        
        
        
To factor both numerator and denominator in this rational expression we are going to substitute 

 with 

; so 

 and 

. This way we can rewrite the expression as follows:

Now we have two much easier to factor expressions of the form 

. For the numerator we need to find two numbers whose product is 

 (30) and its sum 

 (-11); those numbers are -5 and -6. 

 and 

.
Similarly, for the denominator those numbers are -2 and -5. 

 and 

. Now we can factor both numerator and denominator:

Notice that we have 

 in both numerator and denominator, so we can cancel those out:

But remember than 

, so lets replace that to get back to our original variable:

Last but not least, the denominator of rational expression can't be zero, so the only restriction in the variable is 


 
 
        
        
        
Answer:
3x-18 = 39
3x = 57
x = 19
(3*(19))-18 = 39
57-18 = 39  
3x-x+2=4
