A kitten can finish a full bowl of cat food in 60 minutes. An adult cat can finish the same size bowl of food in 20 minutes. When the kitten, the adult cat, and Chungus the Chonky Cat all eat from the same food bowl, they can finish the food in 5 minutes. How long would it take Chungus to finish a bowl of food by himself?

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
