Artaud is 15 years old

Step-by-step explanation:

Imagine Artaud is x yearrs old.

Now, turning the words in the problem into math equations, we get:

-x + 42 = 27.

Solving for x, we get:

-x = -15

x = 15.

So, Artaud is 15 years old.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

answer: 100
