12) The total proceeds from a used book sale were $155. A total of 65 books were sold. The books were priced at $3 and S2 each. How many books were sold for $3? How many books were sold for $2. Use x to
represent 53 books and y to represent S2 books.

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

answer is 17
