Answer: 0.79

Step-by-step explanation:

Given: The cost price of car = $19,000

The rate of depreciation = 21 % = 0.02

The exponential decay equation (depreciation) is given by :-

$y=Ab^x$ , where A is the initial amount and b is the decay factor for x years such that $b=(1-r)$ , where r is the rate of decay.

If we substitute the value of r , we get

The decay factor = $b = (1-0.21)=0.79$

What is... X/2 - 13 = 1

kow [346]

X ÷ 2 - 13 = 1
Write the division as a fraction
$\frac{1}{2}x - 13 = 1$
Multiple both sides of the equation by 2
$2 \times \frac{1}{2}x \times - 2 \times 13 = 12$
Reduce the number with greatest common divisor 2
$x - 2 \times 3 = 2$
Multiply the numbers
$- 2 \times 13$
Then u will have
$x - 26 = 2$
Move constant to the right by adding its opposite sides
$x - 26 + 26 = 2 + 26$
Eliminate the opposites
$- 26 + 26$
Then you have
$x = 2 + 26$
Add the numbers
$x = 28$
