Step-by-step explanation:
<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
Answer:
(a) is 8 x 7 x 3 = 168
(b) is 8 x 7 = 56
(b2) is weird I don't know what it's asking
Answer:
The smaller addend is subtracted from the bigger addend
Step-by-step explanation:
Represent the two numbers with a and b such that a > b
So, the mathematical representation will be

Open the bracket

<em>This implies that the smaller addend (b) is subtracted from the bigger addend (b)</em>
<em></em>
<em>Take for instance; a = 6 and b = 4</em>
<em>This gives</em>

<em>Open the bracket</em>

I got x < 2 for the inequality
