Can someone please help me?

Mathematics
1 answer:
Aneli [31]3 years ago

Answer:

A

Step-by-step explanation:

to find the inverse, there are two steps

1-interchange x and y

2-solve for y

so y=x+1/x

interchange to get x=y+1/y

and solving for y we multiply both sides by y to get xy=y+1

subtract both sides by y yielding xy-y=1

factor out y to get y(x-1)=1

then divide to get y=1/x-1

Ben is 4 times old as ishaan. 6 years ago, Ben was 6 times as old as ishaan <br> How old is Ben now?
SpyIntel [72]

Answer:

60years

Step-by-step explanation:

let Ben age = x

ishaan age = y

Ben is 4 times old as ishaan:

x=4y ..........equation (1)

6 years ago

Ben age = x-6

Ishaan age = y-6

x-6=6(y-6)

x-6=6y-36

x=6y-36+6

x=6y-30..........equation (2)

equating equation(1) and (2)

4y=6y-30

4y-6y=-30

-2y=-30

y=-30/-2=15

substituting the value of y into equation (1)

x=4y

=4*15

=60

Ben age now =60years
