Answer:

The answer to your question is Kevin is 6 years old.

Step-by-step explanation:

Process

1.- Assign a letter to Daniel and another letter to Kevin

Daniel = d

Kevin = k

2.- Write equation that help to solve this problem

      k = d + 3         equation l

       k = 4d             equation ll          four years ago

3.- Solve the system by substitution. Substitute equation ll in equation l

       4d = d + 3

-Solve for d

       4d - d = 3

       3d = 3

         d = 1

-Find k

       k = 1 + 3

       k = 4

4.- Calculate the age Kevin has now

Kevin's age = 4 + 2

                   = 6

Which of the following functions best describes this graph?
sweet-ann [11.9K]

Answer: A. y=x²-9x+20

Step-by-step explanation:

As we can see from the graph there are two x-intercepts: (4,0) (5,0)

The easiest way we can do, is we plug these two values into each of the choices.

A. y=x²-9x+20

(4, 0) YES

(5,0) YES

B. y=x²-8x+18

(4, 0) NO

(5, 0) NO

C. y=x²+9x+20

(4, 0) NO

(5, 0) NO

D. y=x²+x-12

(4, 0) NO

(5, 0) NO

Therefore, the answer should be y=x²-9x+20

Hope this helps!! :)
