Question 492650: I just took a math test and was disappointed to see that I got a "C." I had worked very hard and I DID feel confident in my abilities. Luckily, if I correct my test, I can have the opportunity to retake it and get up to an 80%. I simply need someone to show me how to do the problems I missed and explain what I did wrong.
Here are the questions:
2x^-4/(over)8x^-2 I got 4x^-2. I divided two into eight and had 4 leftover and then used the division of exponent rules (which I obviously used wrong). PLease explain. :)
#2
(3x^4y^-2/{over}4x^-5)^-2
I powered everything by the negative 2 first, and got 9x^-8y^-4/{over}16x^10, simplified and finally got 9/{over} 16x^2y^4
#3
1/4 + 3/8 = 3/4
I multiplied the whole thing by 4/1 and got 1+6y=3, used the addition method, divided by 6 and got y=1/3
#4
x-6 in absolute value lines is less than or equal to -8
I worked this out as a conjunction and got 14 is less than or equal to x is less than or equal to -2. I know the answer is no solution now, I just don't understand why. Could you please explain?
Thank you.
