Since both terms are perfect squares, factor using the difference of squares formula.
a^2- b^2= (a+b) (a-b) where a=x+2y and b=2z
(x+2y+2z) (x+2y-2z)
Answer:
yyeeeett
Step-by-step explanation:
just a guess y'know
Answer:
c
Step-by-step explanation:
f( - 1) with x < 1 , then
f(- 1) = = = 1
f(1) with x ≥ 1 , then
f(1) = x + 1 = 1 + 1 = 2
Thus
f(- 1) + f(1) = 1 + 2 = 3 → c
Yo sup??
I guess the answer should be option B ie
negative correlation
because as the value on x axis increases the value on y axis decreases.
Hope this helps
