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
5/4=15/12
2/3=8/12
15/12+8/12=23/12
It has to be the second one and it’s part of that answer or maybe it’s the third one
Answer:
2>x
y>-1
Step-by-step explanation:
assume y=0 when finding x and vice versa
Y=x-v\b
if that's all your information then that's the answer
