2. josefina deposited $250 into her savir
account. she then saved $40 per mor
which of the following equations show
a, the amount in josefina's saving
account after t months?
a a= 250 + 40t
b a = 250 - 40t
c a = 40 + 250t
d a= 40 + 210t

A

Step-by-step explanation: she already put in the 250 which is a one time thing while the 40 has a variable since it can be put it infinite many times

(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.
