Given: f(x) 3x-1. g(x) 2x^2-3
Blizzard [7]
<h3>Solution:</h3>

f(x) = 3x - 1 = 0

f(x) = x = 1/3

By putting the value of x in g(x), we get

g(x) = 2(1/3)^2 - 3

g(x) = 2(1/9) - 3

g(x) = 2/9 - 3

g(x) = -25/9

<h2>Answer:</h2>

g(x) = -25/9

Which of the following is an acid-base neutralization reaction? (1 point) Sn + 2HBr yields SnBr2 + H2 HCl + KOH yields KCl + H2O
borishaifa [10]

Answer:

Explanation:

Sn + 2HBr =  SnBr₂ + H₂

Here HBr is an acid but Sn is not a base . It is a metal . So it is not an acid - base reaction .

HCl + KOH =  KCl + H₂O

HCl is an acid and KOH is a base so it is an acid base reaction.

2AlCl₃ + 3Ca(OH)₂ =  2Al(OH)₃ + 3CaCl₂

It is an acid base reaction . It is so because aluminium hydroxide is a lewis acid and calcium hydroxide is a base . So it is an acid base reaction .

2C₂H₆ +7O₂ =  4CO₂ + 6H₂O

It is not an acid base reaction . It is actually an example of oxidation reaction in which ethane burns in oxygen to give carbon dioxide and water.
