Answer:
$5 + 2.50k ≤ $20
6 kilometers
Step-by-step explanation:
Puedes viajar con $15 porque gastaste 5 en la tarifa base. 15 dividido por 2,5 es 6, por lo que puedes viajar 6 kilómetros con $20.
 
        
             
        
        
        
Answer: It has two distinct real zeros.
Step-by-step explanation:
 The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:
 
 In this case you have the following Quadractic function provided in the exercise:
 
 Let's make it equal to 0:
 
 
 You can identify that:
 
 Knowing these values, you can substitute them into the formula and then evaluate:
 
 Therefore, since:
  
 You can determine that the it has two distinct real roots.

Answer:
(f + g)(3) = 9
Step-by-step explanation:
Given:
f(x) = x² + 1
g(x) = x - 4
Required:
(f + g)(3)
SOLUTION:
✔️Find f(3) by substituting x = 3 into f(x) = x² + 1:
f(3) = (3)² + 1 = 9 + 1
f(3) = 10
✔️Find g(3) by substituting x = 3 into g(x) = x - 4:
g(3) = 3 - 4
g(3) = -1
✔️Find (f + g)(3):
(f + g)(3) = f(3) + g(3)
= 10 + (-1)
= 10 - 1
(f + g)(3) = 9
