Answer:
It is A ig.
Step-by-step explanation:
6.4 x 10^3 = 6400
1.4 x 10^4 = 14000
7.5 x 10^3 = 7500
total = 6400 + 14,000 + 7500
total = 27900 or 2.79 x 10^4 <===
Answer:
The slope would be -1 :)

<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x + 3
<u>Step 2: Find</u>
- Swap: x = y + 3
- [Subtraction Property of Equality] Isolate <em>y</em>: x - 3 = y
- Rewrite: f⁻¹(x) = x - 3
