Find the inverse of the function d(x) = 2x - 4

Answers

Answer 1

Answer:

Answer:

d(x) = 1/2x + 2

Step-by-step explanation:

Swap x and y:

x = 2y - 4

Add 4 to the other side:

x + 4 = 2y

Divide by 2:

y = 1/2x +2

Answer 2

Answer:

Answer:

see explanation

Step-by-step explanation:

let y = 2x - 4

Rearrange making x the subject, add 4 to both sides

2x = y + 4 ( divide both sides by 2 )

x = $(y+4)/(2)$

Change y back into terms of x, hence

$f^(-1)$ (x) = $(x+4)/(2)$

100,000 equals 10 to the what power?

Answers

Answer: 10 to the 5th power

Step-by-step explanation: Since 100,000 is a whole number, the exponent on our power of 10 will be positive.

To determine the value of the exponent, we first write a decimal point at the end of 100,000.

Next, we count the number of places we would need to move the decimal point in order to get 1.0.

In this problem, we would need to move the decimal point 5 places to get 1.0 which means that we will have an exponent of 5.

Therefore, 100,000 is equal to 10 to the 5th power.

100,000 equals 10 to the power of 5, hope helps.
