ANSWER
The correct answer is B
<u>EXPLANATION</u>
If we analyse the coordinates carefully, you realize there is a mapping of

This is a reflection in the y-axis.
Since the transformation is a reflection, the shape is preserved. Therefore, the image triangle P'Q'R' of triangle
PQR are congruent.
Find the difference per row:
10 seats in the first row
30 seats in the sixth row:
30 -10 = 20 seats difference.
6-1 = 5 rows difference.
20 seats / 5 rows = 4 seats per row.
This means for every additional row, there are 4 more seats per row.
The equation would be:
Sn = S +(n-1)*d
Where d is the difference = 4
S = number of seats from starting row = 10
n = the number of rows wanted
S(11) = 10 + (11-1)*4
S(11) = 10 + 10*4
S(11) = 10 + 40
S(11) = 50
Check:
Row 6 = 30 seats
Row 7 = 30 + 4 = 34 seats
Row 8 = 34 + 4 = 38 seats
Row 9 = 38 + 4 = 42 seats
Row 10 = 42 + 4 = 46 seats
Row 11 = 46 + 4 = 50 seats.

Answer:
-4/5
Step-by-step explanation:
In a line, the slope is the coefficient to x.
In the standard linear equation, f(x) = mx + b, m is the slope.
Since the equation is f(x)= -4/5x + 2, -4/5 is the slope because it is the coefficient to x.
So, the slope is -4/5
The sample size is 36 because 3x12=36
So the correct answer is C
