The present age of the mother is 30 years.

Step-by-step explanation:

Step 1 :

At present,

Age of Jane = x
Age of Billy = 5x
Age of mother = 3(5x) = 15x

Step 3 :

After 2 years,

Age of Jane = x+2
Age of mother = 8 times as Jane = 8(x+2)

Step 3 :

Age of mother at present + 2 years = Age of mother after 2 years

⇒ 15x + 2 = 8(x+2)

⇒ 15x + 2 = 8x + 16

⇒ 7x = 14

⇒ x = 2

Step 4 :

Substitute x=2,

Age of mother at present = 15x = 30 years.

1/(x+4)(x-2)(x-5) excluded values

UNO [17]

Answer:

see explanation

Step-by-step explanation:

The excluded values are any values of x that make the function undefined

Given

$\frac{1}{(x+4)(x-2)(x-5)}$

The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.

(x + 4)(x - 2)(x - 5) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 2 = 0 ⇒ x = 2

x - 5 = 0 ⇒ x = 5

x = - 4, x = 2, x = 5 are the excluded values
