<em>Assume that the given parameter is: 4</em>
Required
The multiplicative inverse
Let a number be x, and the multiplicative inverse be y. The relationship between them is:

Make y the subject

So;; for the assumed given parameter.
The multiplicative inverse is:

Answer:
False
Step-by-step explanation:
3 and 3 add up
6,2,12 and 4 add up
But 9 and 7 don’t it should be like 9 and 18
A double replacement reaction occurs when the ionic parts of two ionic compounds are exchanged.
Reaction 1 results in a product which is a single compound. No ionic parts are exchanged.
Reaction 3 results in one compound being separated into its elemental parts. No ionic parts are exchanged.
Reaction 4 has two reactants, but Pb is an element and not an ionic compound. No ionic parts are exchanged.
Hence, the answer is Reaction 2. Both NaBr and Ca(OH)2 are ionic compounds. Br - is the anion in NaBr, and (OH)2 is also an anion. Ionic parts are exchanged.
1080 is correct hope this helps.
39° because a right angle adds up to 90°
