Acat is running away from a dog. after 5 seconds it is 16 feet away from the dog and after 11 seconds
it is 28 feet away from the dog. let x represent the time in seconds that have passed and y represent the
distance in feet that the cat is away from the dog.

18 feet

Step-by-step explanation:

Given:

A cat is running away from a dog.

After 5 seconds it is 16 feet away from the dog

After 11 seconds  it is 28 feet away from the dog.

Let x represent the time in seconds that have passed and y represent the

distance in feet, so there are two points are formed such as (5, 16) and (11,28).

We will find the distance between dog and cat. by using distance formula of the two points.

Now we substitute the given value in above equation.

18.08 ≅ 18

So

Therefore the distance between dog and cat is 18 feet.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
