Y=10,000(0.97)x predict purchasing power of $10,000 ten years later
Maksim231197 [3]

Answer:

It will be $7602.3

Step-by-step explanation:

The equation y = 10000(0.97)^{x} gives the purchasing power of $10000 after x years.

Therefore, the sum of money $10000 will value 10000(0.97)^{x} after x number of years.

Now, after 9 years i.e. x = 9 years, the sum value of $10000 will become y = 10000(0.97)^{9} = 10000 \times 0.76023 = 7602.3 dollars. ( Answer )

Perform the operation.<br> (6x2 + 7x + 2) - (-9x2 – 10)<br> Perform the operation help please
natita [175]

Answer:

<em>15</em>x^{2}<em> + 7x + 12</em>

Step-by-step explanation:

(6x^2 + 7x + 2) - (-9x^2 - 10)

Flip the sign:

- (-9x^2 - 10) becomes + 9x^2 + 10

Combine like terms:

6x^2 + 7x + 2 + 9x^2 + 10

6x^2 + 9x^2 = 15x^2

2 + 10 = 12

Put it all together:

15x^2 + 7x + 12
