Hello:
x²-4x-1=0
(x²-2(2x) +2²)-2²-1=0
(x-2)² -5 = 0
(x-2)²-(<span>√5)² = 0
(x-2-</span>√5)(x-2+√5) = 0
(x-2-√5=0) or (x-2+√5 = 0)
x=2+√5 or x =2-√5
Answer:
f(x) = 3
Step-by-step explanation:
The function that was graphed is always equal to 3
Answer:
ln 343
Step-by-step explanation:
Using the laws of logarithms
•
x = n ⇔ x = 
• log x + log y ⇔ log(xy)
given 3 ln 7 + 6 ln y, then
=ln
+ ln 
= ln 343
All you have to do is multiply the numbers- 6, 14, 5, 5, and 3. Your answer would be 6300 variations
