4. x1 = -2, x2 =2
Wait what....? No equal signs or inequalities...?
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.
For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.
Sentence one uses<span> the </span>simple past<span> tense. Sentence two </span>uses<span> the </span>present perfect tense<span>. “I saw the movie” and “I have seen the movie” both refer to an action that was finished in the </span>past<span>. But there is one important difference: “I saw the movie” suggests that you saw the movie at a specific time in the </span>past<span>.</span>
Answer:
$65/hour
Step-by-step explanation:
Let C(h) represent the total amount payable to the plumber. Then:
C(h) = $75 + (rate)(2 hr) = $205. Solve for the "fixed hourly rate."
Subtracting $75 from both sides, we get:
(rate)(2 hr) = $130.
Dividing both sides by (2 hr) results in (rate) = $65/hour
