1. y = 2x + 2
so in this case, the slope is 2. Perpendicular slope is a negative reciprocal, which means it would be... -1/2.
2. this is when you do a cube root of 8. You are asking yourself, what is the value of x for the equation, x^3 = 8.
So you get x = 2.
3. for this problem, using the order of operations, you would have to add 7 to each number, so you get 2<2x<15. Then you will divide the numbers by 2, and get 1<x<7.5.
1. What is the slope of the line perpendicular to y-6=-2x-4?
2. Simplify 8 ^1/3. In case that doesn't make sense the problem is simplify 8 to the 1/3 exponent.
3. Solve -5<2x-7<8

On #1 why is it a negative recipricol and not 1/2? Then on #2 I don't see how you are getting that answer. Could you please explain? Thanks.
