The system {y=2,y=-3}

Mathematics
1 answer:
Rudiy273 years ago
4 0

Answer: The system has no solutions because it is inconsistent.

Step-by-step explanation:

This system is an " inconsistent system", this is because each equation:

y = 2 and y = -3

give us a different value for the same variable y (each variable can have only one value at the same time)

So this system is inconsistent, which means that the system has no solutions.

A kilogram of silver contains 5.58×10²⁴ atoms.

<h3>How to determine the parameter</h3>

From the question given above, the following data were obtained:

  • 1 mole of silver = 107.9 g
  • Number of atoms in 1 mole of silver = 6.02×10²³ atoms.
  • Number of atoms in a kilogram of silver is unknown

Now, we shall convert 1 kg of silver to grams (g).

This can be obtained as follow:

1 kg = 1000g

Therefore, 1 kg of silver is equivalent to 1000g.

Now, let's determine the number of atoms in 1 kg (i.e 1000 g) of silver as follow:

If 107.9 g of silver contains 6.02×10²³ atoms.

Then, 1000 g of silver will contain:

= (1000 × 6.02×10²³) / 107.9

= 5.58×10²⁴ atoms.

Thus, a kilogram of silver contains 5.58×10²⁴ atoms.

For what value or values of b is it true that |b| = -b
snow_tiger [21]

Answer:

b =0

Step-by-step explanation:

The only value where  |b| = -b  is when b=0

|0| = -0

0 = 0

Absolute value means non- negative

non-negative = negative

This is only true when we equal zero
