Let a = z^+, the positive integers, and let r be the relation defined by a r b if and only if 3a

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

0 is its x and y coordinate

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

95.03 is the answer. hope this !
