The ratio of boys to girls in the 9th grade is 5 to 6 there are 312 girls how many boys are there?

260 boys

Step-by-step explanation:

multiply 312 by 5/6

(312/6) * 5 = 260

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
