3 days as she will have knitted 2/3 on the first day, 4/3 on the 2nd day and 6/3 on the 3rd day (2 scarves) Hope this helps!
The missing justification in the proof is
<span>B) Substitution property of equality
The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.
Answer:
The answer is 21
Step-by-step explanation:
The inverse of f(x) would be f(x) = 2
- 8.
We can find this by taking the original equation and switching the x and f(x). Once we do this, we solve for the f(x) in its new place and that is the inverse equation. It is taken step by step for you below.
Take the original.
f(x) = 
Now switch the x and f(x)
x = 
Now square both sides.
= 
f(x) + 4
Now subtract 4 from both sides.
- 4 = f(x)
Now multiply both sides by 2.
2 - 8 = f(x)
And once you've returned to f(x) =, then you have your inverse.
