Let the present age of student be x
Present of teacher will be 4x
After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20
According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10
So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.
Hope This Helps You!
You can use the formula to solve for the y-values in the table. Insert the x-value into the equation: y = 2x - 2
(ex. y = 2(1)-2)
So..
x | y
0 | -2
1 | 0
3 | 4
5 | 8
8 | 14
10 | 18
