Answer:
ok so i think it it a or b i don't know but hope i am right
Step-by-step explanation:
We substitute the given into the equation
given: a=-1, b=2, c=

=(

-1
=

-1
=

-1
=

-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:

=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=


×

(denominator should be -2=common)
=

+

=

which also = to -3.5
If you are looking to write an inequality equation that models this situation, then the answer would be:
. The "at most" signals to use the less than or equal to sign.
