225 + 225*0.35 = x
225 + 78.75 = x
303.75 = x
A function assigns the values. The inverse of the function is y = (x+5)/2.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
To find the inverse of the function, the function is needed to be solved for x, and then replace x with y and vice versa. Therefore, the inverse of the function will be,
f(x) = y = 2x - 5
y = 2x - 5
y + 5 = 2x
x = (y+5)/2
y = (x+5)/2
Hence, the inverse of the function is y = (x+5)/2.

Answer:
23 meters
Step-by-step explanation:
You would subtract 24 from 70, and then divide by two.
70-24=46
46/2 = 23
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.
