Answer: if a/b =/ c, then a =/ bc.
Step-by-step explanation:
inverse means to negate, so if somethings positive you need to change it to negative
Answer:
one in a million chance
Step-by-step explanation:
he combination can be 000000 or 999999, or anything in between. Since the odds of getting each digit is 1/10, you multiply 1/10 by itself 6 times. There's literally a one in a million chance of guessing the PIN correctly.
Hmm, interesting
one way would be to multply it out or set it equal to 11x where x is a whole number (if x is not a whole number, then it is not divisible)
11x=7^6+7^5-7^4
undistribute 7^4
11x=(7^4)(7^2+7^1-1)
11x=(7^4)(49+7-1)
11x=(7^4)(55)
56=5*11
11x=(7^4)(5)(11)
divide by 11
x=5(7^4)
aka, find if 11 is a factor of that number
x=5(7^4)
