Answer:

29 dollars

Step-by-step explanation:

first find the cost for one minute

4.35/3 = 1.45$ per minutes

1.45 x 20 = 29 dollars

It would equal 29$ dollars because you divide 20 and 3, and with that answer you multiply by 4.35 :)

Aaron is 5 years younger than Ron. Four years later, Ron will be twice as old as Aaron.
Hunter-Best [27]

Answer:

Aaron’s present age = x - 5 = 6 - 5 = 1

Step-by-step explanation:

Let Ron’s present age be x.  

Then Aaron’s present age = x - 5

After 4 years Ron’s age = x + 4, Aaron’s age x - 5 + 4.  

According to the question;  

Ron will be twice as old as Aaron.  

Therefore, x + 4 = 2(x - 5 + 4)  

⇒ x + 4 = 2(x - 1)  

⇒ x + 4 = 2x - 2

⇒ x + 4 = 2x - 2

⇒ x - 2x = -2 - 4

⇒ -x = -6

⇒ x = 6

Therefore, Aaron’s present age = x - 5 = 6 - 5 = 1

Hope this answer helps you :)

Have a great day

The graph shows f(x) = 1/2 and its translation, g(x).
AnnyKZ [126]
As you can see, each point on f(x) is moved up 4 units to get to g(x), so the function is g(x) = f(x) + 4.  The f(x) function cannot possibly be f(x)=1/2, though, because that would be a horizontal line through y = 1/2 and that function is clearly not a horizontal line.  So whatever f(x) is REALLY, add 4 to the tail end of it to show its translation.
