Pleas help Geometry homewor, very stuck. Write a counterexample that disproves each conjecture below.
1) If x >_ 0, then x + 2 = 7.

2) If x2 =16 , then x = 4.

if you need , reply with more info. u.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

i don't know

step-by-step explanation:
