and since you multiply 4 by itself 3 times, that becomes
.
The final product is
.
Y=13
(when you have fractions like the one in this problem, you get rid of them by multiplying both sides by the denominator.)
Answer:
The solution is y> -1
Step-by-step explanation:
y- 6 > -7
y> -7+6 (add 6 on both sides)

The answer to the first part is D
