The answer is B. 6.5f+2.5 because 13/2 is 6.5 and 5/2 is 2.5
Answer:
The two numbers can be -12 and 11, or 11 and -12.
Step-by-step explanation:
xy=-132
x+y=-1
-------------
x=-1-y
(-1-y)y=-132
-y-y^2=-132
-y^2-y-(-132)=0
-y^2-y+132=0
y^2+y-132=0
factor out the trinomial,
(y-11)(y+12)=0
zero property,
y-11=0, y+12=0,
y=0+11=11,
y=0-12=-12
x+11=-1 & x+(-12)=-1
x=-1-11=-12
x=-1-(-12)=-1+12=11
