Marlye posted a story on her blog. On the first day there were 80 responses and on the second day there were 180 responses. What percent is the increase 100 of the original number of responses

125%

Step-by-step explanation:

Since we already know that there was an increase of 100 responses, we have to divide 100 by 80 and multiply by 100:

100/80 * 100

= 125%

There was a 125% increase in the number of responses.

a and c

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.
