"If a = − 9 and b = − 6, show that (a−b) ≠ (b−a)."

(-9+6) is not equal to (-6+9)

-3 is not equal to 3

hence proved ✌

hope that helps ✌

Step-by-step explanation:

LHS  a - b = -9 - (-6) = -9 +6 = -3

RHS  b-a = -6 - (- 9) =  -6 +9 = 3

as LHS not equal to RHS

a-b not equal to b-a

Thus proven

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
