Y is directly proportional to the positive square root of (x+2)when x=7,y=9. Find y when x=23

15

Step-by-step explanation:

Given: y is directly proportional to when x = 7, y = 9

To find: y when x = 23

Solution:

u and v are said to be proportional if where k is a constant of proportionality.

As y is directly proportional to when x = 7, y = 9,

Put x = 7, y = 9

Put x = 23

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
