Ishaan is 72 years old and william is 4 years old.
how many years will it take until ishaan is only 5 times as old as william?

It will take 13 years to Ishaan age will be 5 times  William age. By this time William will be 17 years old and Ishaan will be 85 years old.

Step-by-step explanation:

By expressing the age of Ishaan and William since today, we have.

I=72+x

W=4+x

Where x is years since today. We want the time for Ishaan age will be 5 times William's age:

I=5W

72+x=5*(4+x)

72+x=20+5x

72-20=5x-x

52=4x

x=13

the f

last graph i believe

step-by-step explanation:

worked it out i believe

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
