Answer:
41 over 24
Step-by-step explanation:
7 2/3 can be "translated" into 3 times 7 plus 2 which is 22, so now it's 22 over 3.
5 5/8 can be "translated" into 8 times 5 plus five is forty five, so now it's 45 over 8.
We now need a common denominator.
Multiples of 8: 8, 16, 24, 32
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24
24 are both multiples of 8 and 3.
Now you have to multiply 22 and 8 because 3 times 8 equals 24 and so you have to do it to the numerator.
22*8=176
Now you have to multiply 45 and 3 since 8 times 3 equals 24 and so you have to do it to the numerator, too.
45*3=135
All you have to do now is subtract 176 from 135 which is 41
4n - 7 = 13
4n = 20
n = 5. Hope it helps!

Answer:
Domain: (-∞, -5) ∪ (-1, ∞)
Step-by-step explanation:
Note:
For f(x) > 0: See the points of x for which the graph of f(x) lies above the x-axis.
For f(x) < 0: See the points of x for which the graph of f(x) lies below the x-axis.
We need to find the domain of f(x) for which f(x) < 0
From the graph, we can tell:
f(x) < 0 on (-∞, -5) ∪ (-1, ∞)
Therefore: The domain on which the given graph f(x) is negative, is (-∞, -5) ∪ (-1, ∞)
