Answer: D
Explanation because there is no point in having to know other skills. that don't evolve your job.
Answer:
Hours Wages = $7.5 / Hour
Since we do not know the tips , let us assume it is x
Carmen Worked 24 hours
Total amount she earned = (24*7.5) + x = 250
180 + x = 250
x = 250-180 = 70
Carmen should earn tips more than $ 70 in 24 hours in order her to receive more than $250 in that week
Explanation:
The correct answer is - 2. There's an increase in the number of snakes and insects, and the storks face increased competition for food.
The significant decrease in the number of eagles, because of the human activity, and of the rabbits, because of a virus, has been of great use for the populations of the snakes to increase, as well as the populations of the insects. That has happened because the snakes lost their predator, and the insects lost a competition for a food source, so their numbers rose.
On the other hand, because of the increase of the number of snakes, the storks had started to face increased competition, as both have the same food source, the frogs.
Recall that √x has a domain of x ≥ 0.
So, f(x) is defined as long as
(x + 1)/(x - 1) ≥ 0
• We have equality when x = -1
• Otherwise (x + 1)/(x - 1) is positive if both x + 1 and x - 1 are positive, or both are negative:
Then the domain of f(x) is
x > 1 or x ≤ -1
On the other hand, g(x) is defined by two individual square root expressions with respective domains of
• x + 1 ≥ 0 ⇒ x ≥ -1
• x - 1 ≥ 0 ⇒ x ≥ 1
but note that g(1) is undefined, so we omit it from the second domain.
Then g(x) is defined so long as both x ≥ -1 *and* x > 1 are satisfied, which means its domain is
x > 1
f(x) and g(x) have different domains, so they are not the same function.
