Answer:
The 8 should have remained positive.
Step-by-step explanation:
8-(-2)=8+2=10
Two negatives make a positive so 8-(-2) will turn into 8+2.
Laura was wrong because she thought the 8 turned to a negative but that makes no sense.
Answer:
C.
Step-by-step explanation:
To find slope using coordinates, use the formula above.
Now, using the formula, plug in as (slope) and either coordinate as the and values. It looks like this:
To solve for , continue to use PEMDAS.
Now use and to solve for your equation:
The answer is C.
To find a percent from a decimal, you multiply the decimal by 100. So, the answer would be A.
Answer:
The answer is -343.
Step-by-step explanation:
If a term doesn't have an exponent, it's considered that the exponent is 1 (so basically, (-7)² x (-7)^1.
Multiply the terms with the same base (by adding the exponents - (-7)²+1<- (as the exponential value) (couldn't find the sign so sorry.)
Add the numbers: (-7)³
A negative base raised to an odd power equals a negative: -7³
Write the problem out: -(7 x 7 x 7).
Multiply: -343
