Select the correct answer.<br> Find the inverse of function f.<br> f(x) = 1/2x + 7

timofeeve [1]

Answer:

f'(x)= 2x - 14

Step-by-step explanation:

change f(x) to y y = 1/2x + 7

switch x and y x = 1/2y + 7

multiply everything by 2 to cancel the denominator 2x = y + 14

solve for y 2x - 14 = y

then change y to f'(x) f'(x) = 2x - 14

zysi [14]

Answer:

0.7755

Step-by-step explanation:

If 120 CDs are defective, the number of non-defective CDs in the batch is:

$n=1950-120\\n=1830$

In order for the batch to be accepted, all of the 4 CDs in the sample must not be defective, the probability of that happening is:

$P=\frac{1830}{1950}*\frac{1829}{1949} *\frac{1828}{1948} *\frac{1827}{1947}\\P=0.7755$

The probability that the entire batch will be accepted is 0.7755.

The number of text messages (t) that katie sends depends on the number of days (d) she is on vacation. the equation is t=50d+20.

pishuonlain [190]

Based on the equation katie gets 20 text messages + 50 more for each day she is away.
therefore the number 50 shows how much the number of text messages (t) increases for each day she is away.
