Answer:

option A  and D

Step-by-step explanation:

the given expression is 6^{-3}

To remove negative sign from exponent we apply a property

a^{-m} = \frac{1}{a^m}

6^{-3} = \frac{1}{6^3}

6^3 = 6*6*6= 216

So 6^{-3} = \frac{1}{6^3}= \frac{1}{216}

two options are correct

\frac{1}{6^3} and \frac{1}{216}

1/6^3 is also equivalent to 6^-3. It can be reverted back to 1/216. Answers on ed2020 are A. and D.

Solve y=f(x) for x then find the input when the output is 6 <br><br> f(x)=x+9
r-ruslan [8.4K]

x = -3

So to figure this out we can readjust the equation to make it easier to solve

f(x) = x + 9 is equal to x+9 = 6

From here we can just subtract 9 from both sides and we get our answer!

x+(9-9) = (6-9)\\x = -3

Pita has 12 coins in her bag.
Allushta [10]

Answer:27/220

Step-by-step explanation:

She must have 2 �1 coins and 1 50p coin.

She can choose the 2 �1 coins 3C2 = 3 ways.

For each of those 3 ways she can choose the

50p coin 9C1 or 9 ways.

That's 3�9=27 ways to get �2.50.

She can choose any 3 coins in 12C3 = 220 ways.

The desired probability is 27 ways out of

220 ways,or 27/220, or 13.5% of the time.
