Which graph is inverted

y = 1+x^2
y = 1 - x^2
y = x^2 -1
-y = 1 - x^2

Please help me and my question, it would mean alot, I think that the graph inverted is D

Step-by-step explanation:

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
