Combine like terms:
-2.5y + 8y - 10.5y=
-13y + 8y =
-5y
The coefficient is -5
When evaluating b^2c^-1 for b=8 and c=4, the answer is -16
E = b^2c–1
x-a = 1/xa
E = b^2c - 1
= 8^2 x (-4)-1
= 64/-4
= -16
Answer:
77
Step-by-step explanation:
just do 500-423
Explanation:
Regardless of the number of factors, the product will be negative if an odd number of factors are negative.
