Jason was recently hired by a security company to design a new password system for a client. He has come up with 4 different designs. Which of the following should Jason choose, assuming he wants to select the one that is the toughest to crack? A) 5 digit password that uses letters only B) 6 digit password that uses a combination of even numbers from 1-9 and vowels C) 8 digit password that uses the numbers 1-9 D)4 digit password that uses a combination of letters and the numbers 1-9

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

the answer should be a. snail

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
