Answer:
7 Weeks
Step-by-step explanation:
If she starts off with 40 reps for the first week, and she adds 6 reps a week, until she gets to 82 reps a week, then it would be<em> 40 + 6 x answer = 82</em>. Now, there are a couple ways you can do this, but the easiest but not shortest way is to do it one by one.
so, <em>40+6x1= 46</em>
<em>40+6x2= 52</em>
<em>40+6x3= 58</em>, and so on and so forth, until you get to <em>40+6x7</em><u>,</u> which equals 82, therefore giving you the answer of 7, but the way quicker way is to take the total (82) and subtract the number of reps she starts out with (40), then divide that number by the amount that it increases each week (6), so:
(82-40)÷6, which will also give you the answer of 7, or 7 weeks.

Answer:
1/3x +4
is the inverse of f(x) = 3x + 4.
Check:
The purpose of the inverse property of multiplication is to get a product of one. So the inverse multiplied with the original number (or equation) should give us the product of one.
1 / (3x + 4) * 3x + 4 = 3x+4 / 3x+ 4 = 1
Answer:
By using Carl Gauss's clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.
