I got -13/40

 

yup that is what i got too

 

Life, the universe, everything!

 

No more math problems?

 

see this isn't the actual test, this is just a study guide for what is similar to what is on the test

Answer some of these:

Simplify:

All in HUGE parenthesis:

2x(to the 7th power) Y (to the second power)
-----------------------------------------------------
4xy(to the third power)




If 2x+2 >(but has a line under it) 5x + 11 then




Simplify:

(-6A(secondpower)B(second power)) (2A(4th)b(2nd))

 

When multiplying variables with exponents (x^2, x^9), you ADD the exponents. Thus x^2*x^9 = x^(2+9) = x^11. When dividing, subtract the exponents. y^5/y^2 = y^3. And, yes, you can have a negative exponent.

Also, it doesn't matter if you have two variables. In the first problem the answer is x^6/2y

 

BTW, y^-2 = 1/y^2

 

Of course this is the best answer.

 

The first one is 1x^6/2y^-1

Second one is -3 >= x

Third one -- -12a^6b^4

I think I got them all but please someone double check

 

I'm ing confused.

I just spend 10 minutes figuring this one out:

If -6(2x + 1) = -4x + 10, then x=


WHAT?! the ing X who cares?!!!!
