Of the 130 eighth graders at Franklin Middle school, 30 students play in the band, 22 students acted in the school play, and 12 of these students did both. How many are neither in the band nor acted in the play?

true

explanation:

hi! i think the answer is 1/2 : )

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
