Answer:
g=3
Step-by-step explanation:
multiply x with x-4 and +7 with x-4 to open the brackets
x^2 - 4x + 7x - 28 = x^2 +gx - 28
x^2 + 3x - 28 = x^2 + gx -28
x^2 - x^2 + 3x -28 + 28 = gx
gx is kept alone on the other side because we have to find value of g
cancel out +x^2 -x^2 and +28 -28
we ll be left with
3x = gx
divide both sides by x
3x/x = gx/x
cancel out x in the numerators with the x in the denominators
3 = g

Answer:
can you give me the page number and book name .
please be specific with the book name.
For your answer
or
you can find your answers on the last pages of the book just look for the section and the one you are doing.
For what are you trying to figure out?
Exponential functions can be expressed as:
f=ir^t, f=final value, i=initial value, r=rate or common ratio, t=term number or "time" when it is fractional...In this case we have:
f=100((100-11)/100)^x
f=100(0.89)^x and we want to solve for when f=15 so
15=100(0.89)^x
