Domain ( all possible values of x) is x > 5 or in interval notation it is (5, ∞)
The range( all possible values of log x) is (-∞, ∞)
Percentage of sugar is : 2/12 = 0.166 rounds to 0.17 = 17%
ok Step-by-step explanation:
Move everybody to one side
minus 5x+2 both sides
x^2-5x-2=0
use quadratic formula where
if you have
ax^2+bx+c=0
x=

1x^2-5x-2=0
a=1
b=-5
c=-2
x=

x=

x=

aprox
x=5.372281323 or -0.3722813233
