There are 5 couples are sitting in the row
<h3>How many couples are sitting in the row?.</h3>
The given parameters are
Maximum = 6 couples
In the hall, we have the following arrangements
<u>First couple</u>
Right = 2 couples
Left = 1 couple
<u>Another couple</u>
Left = 3 couple
Right = 1 couples
The left of the other couple is the right of the first couple
So, we have the following arrangements:
<u>First couple (1)</u>
Right = 2 couples
Left = 1 couple
<u>Another couple</u>
Right = 1 couples
The total number of couples is
Total = 1 + 2 + 1 + 1
Evaluate the sum
Total = 5
Hence, there are 5 couples are sitting in the row

Answer:
(0, 3 )
Step-by-step explanation:
To find the y- intercept , substitute x = 0 into f(x), that is
f(0) = 3 ×
[ note
= 1 ]
= 3 × 1
= 3
y- intercept = (0, 3 )
Answer: [<em>b + 4 = -10</em>]
Step-by-step explanation: We are given the equation <em>b = -14</em> and told to, given this information, evaluate <em>b + 4 = ?</em> and find <em>?.</em> Given b = -14 we can plug in <em>-14</em> for <em>b</em> in <em>b + 4 = ?</em>. This gives us <em>-14 + 4 = ?.</em> Adding this up gives us the answer of -10. Hope that this makes sense and helps, and good afternoon to you!
