Marco wants to buy 2 books that cost 20$ each. He can save $5 a week. Draw diagrams and write equations to find how many weeks it will take hime to save enough money to buy the books.

8 weeks

Step-by-step explanation:

because you multiply the two books to get the total price then divide by 5 to get how many weeks he has to save 5 dollars

"a" determine whether sage found the correct quotient. show your work

step-by-step explanation:

(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.
