The last one does not represent a function because for it to be a function none of the x’s can repeat and in the last one the 0 repeats.
Start by proving to them that the number 0.57 can be converted into a fraction . A whole number can't exactly be put in to a fraction. 0.57 can be converted to 14.25/25. This information means that 0.57 IS a rational number. Hope this convinced them!
Start with
Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:
Subtract 3 from both sides:
1764 is the answer your welcome I Siam’s this during my science homework
(−2)³ = (-2)(-2)(-2)
Note that:
two negative numbers multiplied together results in a positive
one negative and one positive number multiplied results in a negative
Multiply:
(-2)(-2) = 4
4(-2) = -8
-8 is your answer
hope this helps
