Answer:
the answer would be B
Step-by-step explanation:
for the slope you would need to count up then over between the two points and do that until you reach where the line crosses or in this case would cross for the y-intercept
Using an arithmetic sequence, it is found that the opera house will have 6150 chairs.
<h3>What is an arithmetic sequence?</h3>
In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:

In which
is the first term.
The sum of the first n terms is given by:

In this problem, the sequence is:

Hence the first term and the common ratio are given, respectively, by:

Then the 50th term is:

The number of chairs is the <u>sum of the first 50 terms</u>, hence:

Next time, please include the instructions: "Solve for x:"
Starting with 3x + 2 > x - 8
subtract 2 from both sides, and also subtract x from both sides, obtaining
2x > - 10
Divide both sides by 2: x > -5
