4 Which equation will solve the following word problem? Sue's class has 50 students. 20% of the students are in art class. How many students are NOT in art class?
Will give brainliest for correct answer

a)50/(50 * 0.20) = x

b)50 + (50 * 0.20) = x

c)50 - (50/0.20) = x

d)50 - (50 * 0.20) = x

For which pair of functions is (gof)(a)=|a|-2?

Which expression gives you the distance between the points (5,1)and(9,-6)

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
