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
Answer:
180
Step-by-step explanation:
When you multiply the about lost per hour by the amount of time, you get the amount lost total.
6*8=48
then you add that to the amount in the pool now, and you have the original amount.
Answer:
-5.55-4.2c
Step-by-step explanation:
-5.55-8.55c+4.35c
-8.55c and 4.35c are like terms so you have to combine them.
-8.55c+4.35c=-4.2c
-5.55 is NOT a like term so it is on its own.
final answer -> -5.55-4.2c
*** don't forget -5.55 is negitive ***
hope this helped negative:)
