Answer:
f(x) = 4x
Step-by-step explanation:
Verification:
f(2) = 4 x 2 = 8
f(3) = 4 x 3= 12
f(4) = 4x x 4 = 16
Step-by-step explanation:
Let the present age of father = x years
and the present age of son = y years
according to the first condition
x + y =44 ........(i)
according to the second condition
x+8 = 2(y+8)
or x+ 8 = 2y + 16
or x- 2y = 8 ............(ii)
solve the equation (i) & (ii) we get
x + y =44
x- 2y = 8
••••••••••••••••••••••••
3y = 36
or y = 12
put the value of y in equation (i), we get
x + 12 =44
or x = 32
so the present age of father = x =32 years
and the present age of son = y = 12 years.
X= 1/7k + 19/7
(the ones that look like this: 1/2 are fractions. Hope I helped
