Answer:
rational equation
Step-by-step explanation:
A rational equation is an equation containing at least one fraction whose numerator and denominator are polynomials, \frac{P(x)}{Q(x)}.
Hello!
We'll start by simplifying the required formula. (f – g)(x) can be rewritten as the following:
f(x) – g(x)
Now insert any known values into the simplified formula above:
(-5x – 4) – (-3x – 2)
Eliminate the parentheses by simplifying:
-5x – 4 + 3x + 2
Combine like terms:
-2x – 2
We have now proven that (f – g)(x) is equal to (-2x – 2).
The correct answer is C.
I hope this helps!
I hope it helps, let me know if it’s right
Think:
7:55 a.m. is 5 minutes (5/60 hrs) before 8 a.m.;
from 8 to noon it's 4 hours, and from noon to 2:40 p.m. is 2 2/3 hours.
Thus, you're in school 5/60 hrs + 4 hrs + 2 2/3 hrs, or
6 2/3 hrs + 5/60 hrs, or 6 40/60 hrs + 5/60 hrs, or
6 45/60 hrs, or 6 3/4 hrs.
Of course there are other ways in which you could do this problem:
4 hrs 5 min plus 2 hrs 40 min comes out to 6 hrs 45 min, or 6 3/4 hrs.
