Sqrtx = x - 12
x = (x -12)^2
x^2 - 24x - x + 144 = 0
x^2 -25x + 144 = 0
(x - 16)(x - 9) = 0

x = 9, 16 

Check  to see if these fit the equation:-

x = 16 :-
sqrt16 + 12 = 16
16 = 16  So  x =16 is a root

x = 9:-

sqrt9 + 12 = 9
3 + 12 = 9  This is NOT a root 

There is only one root which is  x = 16.  9 is  an extraneous root which you get sometimes in equations containing radicals.

Carrie borrows 960 interest fee to pay for a car repair. She will repay $120 monthly until the loan is paid off. How many months
lesya692 [45]

We are told that Carrie borrows $960 interest free to pay for a car repair. She will repay $120 monthly until the loan is paid off and we are asked to find how many months will it take Carrie to pay off the loan.

In order to find out the number of months to pay off the loan we will divide total amount borrowed by monthly loan installment.

\text{Number of months to pay off the loan}=\frac{960}{120}=8

Therefore, Carrie have to pay $120 for 8 months to payoff the loan.

Drag the tiles to the correct boxes to complete the pairs. Kevin has diabetes -
sashaice [31]
1) The probability that Kevin has diabetes and the test predicts opposite to be true = Probability Kevin has diabetes x Probability that test predicts opposite to be true.

Probability that Kevin has diabetes = 0.75
Probability that test predicts opposite to be true (i.e test predicts he doesn't have diabetes) = 0.15

So,
The probability that Kevin has diabetes and the test predicts opposite to be true =  0.75 x 0.15 = 0.1125

2) The probability that Kevin does not have diabetes and the test predicts this correctly = Probability Kevin does not diabetes x Probability that test predicts this correctly.

Probability that Kevin does not have diabetes = 0.25
Probability that test predicts this correctly (i.e. test predicts he does not have diabetes) = 0.85

So,
The probability that Kevin does not have diabetes and the test predicts this correctly = 0.25 x 0.85 = 0.2125

3) The probability that Kevin does not have diabetes and the test predicts the has diabetes = Probability Kevin does not diabetes x Probability that test predicts he has diabetes.

Probability that Kevin does not have diabetes = 0.25
Probability that test predicts has has diabetes = 0.15

So,
The probability that Kevin does not have diabetes and the test predicts the has diabetes = 0.25 x 0.15 = 0.0375

Please help and thank you!
aleksklad [387]

Answer:

1/(k^2)

Step-by-step explanation:

Because the k's are above one another in the fraction format, using exponent rules you would subtract the top number exponents with the bottom number exponents (note do not do anything with the letter k). 5-7= -2, and k^-2 is the same as 1/(k^2).

Hope you have a great day and this helps! :)
