Artemon [7]

Answer:

14 3/4 years

Step-by-step explanation:

Let's assume compound inflation. The appropriate formula for that is:

A = P(1 + r)^t.

If we represent current prices by P, then double that would be 2P:

2P = P(1 + 0.048)^t Find t, the time required for prices to double.

Then:

2 = 1.048^t

Taking the natural log of both sides, we get:

ln 2 = t·ln 1.048, so that:

t = (ln 2) / (ln 1.048) = 14.78

At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.

How do u graph x+y=-2

sdas [7]

Answer:

The answer is

$y = - x - 2$

Step-by-step explanation:

The problem is

$x + y = - 2$

First we have to bring x to the other side se we subtract x from both sides

$x + y = - 2 \\ - x \: \: \: = - 2 - x$

Then we have to put it in order so the answer is

$y = - x - 2$
