Answer:
≤
Step-by-step explanation:
let the number of books purchased = x
cost of each book = $8
Cost incurred on books = 8x
money to be saved for miscellaneous expenses= $15
Total cost = 8x+15
We are given that total cost need to be less than or equal to $65
Hence
8x+15≤65
subtracting 15 from both sides
8x≤50
diving both sides by 8

the answer is yes, because they intercept the same arc*
Try plugging in the 4 solutions and see if they fit
for example a, x - 6 is not extraneous because
left side = sqrt (-3*-6 - 2) == sqrt16 = 4 or -4
right side = -6 + 2 = -4
so x = -6 is not extraneous
