F(-x) = 2/-x/ + 3(-x) = 2/x/ - 3x;
Answer:
28 students
Step-by-step explanation:
30% is equal to .3
40 x .3 equals 12
This means the class has lost 12 students.
40 - 12 is 28.
Another way:
Because the class has lost 30% of it's students, you know that the class is 70% of it's original capacity.
70% is equal to .7
40 x .7 is 28

Answer:
{f, a}
Step-by-step explanation:
Given the sets:
X = {d, c, f, a}
Y = {d, e, c}
Z ={e, c, b, f, g}
U = {a, b, c, d, e, f, g}
To obtain the set X n (X - Y)
We first obtain :
(X - Y) :
The elements in X that are not in Y
(X - Y) = {f, a}
X n (X - Y) :
X = {d, c, f, a} intersection
(X - Y) = {f, a}
X n (X - Y) = elements in X and (X - Y)
X n (X - Y) = {f, a}
