Answer:
The sale price will be: $215.10
Step-by-step explanation:
We know that:
Sale price = Regular price × (100% - Discount %)
= Regular price × (100% - 10%)
= 239 × 90%
= 239 × 0.9
= 215. 10 $
Therefore, the sale price will be: $215. 10
Answer:
<em>Thus, f and g are inverse functions</em>
Step-by-step explanation:
<u>Inverse Functions</u>
If two functions f(x) and g(x) are inverses, then it follows that:
Or:
We are given
Let's test if they are inverse functions:
Simplifying:
Now find:
Operating:
Thus, f and g are inverse functions
8 - 3x - x = 12
8 - 2x = 12
-2x = 12 - 8
-2x = 4
x = -2
