Answer:y
=
2
x
−
y
Step-by-step explanation:
Commutative property of addition:
a + b = b + a
Associative property of addition:
a + (b + c) = (a + b) + c
Opposite of a sum:
- a - b = - (a + b)
If we look at the options, A and D follow associative property.
B follows commutative property.
C follows opposite of a sum property.
You can simplify the right side. Then, you need to take cube roots.
(m -4)³ = 1/(1/8) . . . rule of exponents
(m -4)³ = 8 . . . . . . .simplify
m -4 = ∛8 . . . . . . . take cube roots
m -4 = 2 . . . . . . . . use your calculator or knowledge to find ∛8
m = 6 . . . . . . . . . . add 4
The solution is m = 6.
_____
If you subtract the right side, you get a function of m that is zero when m has the right value. This graph shows that value is m = 6.
