Answer:
(c) x = 2 and x = -8
Step-by-step explanation:
The rules of logarithms let you rewrite this as a quadratic equation. That equation will have two (2) potential solutions. We know from the domain of the log function that any negative value of x will be an extraneous solution.
__
The rules of logarithms that apply are ...
__
<h3>take antilogs</h3>
We can rewrite the equation so that only one logarithm is involved. Then we can take antilogs.
__
<h3>solve the quadratic</h3>
Adding (6/2)² = 9 to both sides will "complete the square."
16 +9 = x² +6x +9 . . . . . . . add 9
25 = (x +3)²
±√25 = x +3 = ±5 . . . . . take the square root(s)
x = -3 ±5 = {-8, +2}
The two potential solutions are x = 2 and x = -8.

Answer:
An equation modeling the situation is : 4 m + 6 n = 180
Step-by-step explanation:
Here, the total number of guests in the banquet hall = 180
Let us assume number of tables ordered with capacity of
4 people each = m
And number of tables ordered with capacity of 6 people each = n
So, total number of people in m tables = m x ( Capacity of 1 table)
= m x (4) = 4 m
And, total number of people in n tables = n x ( Capacity of 1 table)
= n x (6) = 6 n
So, the total capacity of ( m + n) tables = 4 m + 6 n
Also, the total required capacity = 180
⇒ 4 m + 6 n = 180
Hence, an equation modeling the situation is : 4 m + 6 n = 180
Answer:
first dice-4/6
second dice-5/6
Step-by-step explanation:
if you have six possible outcomes for the first dice and you want it to roll 1 thru 4 then you have a four out of six chance and you have a 5 out of six chance for the second dice
