Answer: 5x^(-1) or 5/x.
Step-by-step explanation: The equation given is (5*x^2)/x^3 and we are supposed to solve it for x = 2. First. we simplify the equation. Since we have x^2 in the numerator and x^3 in the denominator, using the equation a^x/a^y = a^(x - y) we find that we get 5*x^(-1) we can leave it like this or simplify it to 5/x, since negative exponents mean fractions.
The slope is 5/4

Answer:
Step-by-step explanation:
Total sum of age of 12 students = 12*18 = 216;
Total sum of age of 8 students = 8*23 = 184;
Total sum of age of 20 students = 216+184 = 400;
Mean age of all the students = total age / number of students;
= 400/20 = 20 year
