Answer:
(- 5, 4)
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y) → (y, x)
Hence
G(4, - 5) → G'(- 5, 4)
The expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54
<h3>How to determine the expression?</h3>
Let the number of students in 2010 be s.
So, we have:
- Year 2011 = 1/2s i.e. half as many students in 2010
- Year 2012 = s - 54 i.e. 54 students less than 2010
The total number of students is:
Total = s + 1/2s + s - 54
Evaluate
Total = 9s/2 - 54
Rewrite s:
Total = 5.5s - 54
Hence, the expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54
