First, let us define our variables.
Let
x = age of the father
y = age of the son
z = age of the daughter
5 years ago..
(x – 5) = age of the father
(y – 5) = age of the son
(z – 5) = age of the daughter
After 18 years...
(x + 18) = age of the father
(y + 18) = age of the son
(z +18) = age of the daughter
From the first condition
y = z + 5 à
eqn 1
5 years ago
(x-5) = 23 + (y-5) + (z-5)
x –y –z = 18 à
eqn 2
after 18 years
(x+18) = 17*[(y +18 –z – 18)]
x – 17y + 17z = -18 à
eqn 3
solving the 3 equations simultaneously
x = 67
y = 27
z = 22

Step-by-step explanation:
Answer:
b. ![\sqrt[3]{4x+2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4x%2B2%7D)
Step-by-step explanation:
f(x) = ( x^3-2) /4
y = ( x^3-2) /4
Exchange x and y
x = ( y^3-2) /4
solve for y
Multiply each side by 4
4x = 4( y^3-2) /4
4x = y^3 -2
Add 2 to each side
4x+2 = y^3
Take the cubed root of each side
( 4x+2) ^ (1/3) = y^3 ^(1/3)
( 4x+2) ^ (1/3) =y
