3ln(2x) + 7 = 15. how do i do this

Step-by-step explanation:

3 ln(2x) + 7 = 15            Subtract 7 from both sides

3 ln(2x)  = 15 - 7            Combine

3 ln(2x) = 8                    Divide by 3

  ln(2x) = 8/3                Do the division. Take the antilog of both sides.

e^ln(2x) = e^(8/3)

2x = 14.392                   Divide by 2

x = 14.392

x = 7. 196

a negative exponent is translated as follows:

so, we have

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
