The answers C because it is below sea level and sea level is 0 so it has to be negative
Answer: 8 hrs and 3/4 of an hour (three quarters)
Step-by-step explanation:
the same logic such as a quarter of an hour
Answer: Second option.
Step-by-step explanation:
Given the functions f(x) and g(x):

You need to divide them in order to find
asked in the exercise. Then:

Now, it is important to remember that, by definition, the division by zero is not defined. Therefore, the denominator of the function cannot be zero.
Let's find the value of "x" for which the denominator of the function would be zero:
1. You need to make the denominator equal to zero:

2. Finally, you must solve for "x":

Therefore, as you can see, the answer is:
, 
Answer:
x=16, y=-4
Step-by-step explanation:
-1(x-y=12)
x+7y=-20
-x+y=-12
x+7y=-20
8y=-32
y=-4
x-4=12
x=16
Answer:
y = 108°
Step-by-step explanation:
Since AB and CD are parallel lines, then
3x - 12 and 2x + 16 are corresponding angles and congruent, thus
3x - 12 = 2x + 16 ( subtract 2x from both sides )
x - 12 = 16 ( add 12 to both sides )
x = 28
Thus
3x - 12 = 3(28) - 12 = 84 - 12 = 72°
y and 3x - 12 are adjacent angles and supplementary, thus
y = 180° - 72° = 108°
