The ratio of boys to girls in a school choir is 5:3. There are 6 more boys than girls. In 3 more girls join the choir, what will be the new ratio of boys to total students in the choir?

5:9

Step-by-step explanation:

If there are 6 more boys than girls, that means that there are 15 boys and 9 girls. If 3 more girls join, there are 12 girls. The total number of students is 27. The ratio is 15:27 or 5:9.

(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.
