Answer:
B
Step-by-step explanation:
5/1 is not equal to 6/2 or 7/3 or 8/4
Answer:
Step-by-step explanation:
Given is a differential equation as

Divide this by t to get in linear form

This is of the form
y' +p(t) y = Q(t)
where p(t) = 1/t
So solution would be

siubstitute y(1) = 16

Answer:
C. x^2 -4
Step-by-step explanation:
What you do is subtract the functions as said by
(f-g)(x).
so:
f(x)-g(x)
(2x^2+3) - (x^2 -7)
2x^2 -x^2 +3 - 7= x^2 -4
