Clara has pennies and quarters in her purse. She counts a total of 28 coins. If the total value of the coins is 76 cents, which system of equations can be used to determine the number of pennies and the number of quarters? Assume p represents the number of pennies and q represents the number of quarters. p + q = 28. p + 25 q = 76.
p + q = 28. 25 p + q = 76.
p + q = 76. p + 25 q = 28.
p + q = 76. 25 p + q = 28.

i hope this is what you were looking for.

see attached graph

(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.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
