Alexander started with 40 pieces of candy and gave away x pieces. Tristen started with 65 pieces of gum and gave away twice as many pieces as Tristen did. How many pieces of gum was given away if they had the same number of pieces of gum left?

35

Step-by-step explanation:

x + 2x=3x        65+40=105

105/3x=35

i will pick c put check it over to be sure

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.
