Correct Options are:

Option A: (Negative one-fourth) cubed

Option B: Negative (one-fourth) cubed

Option D: Negative (StartFraction 1 Over 8 EndFraction) squared

Option F: Negative (one-half) Superscript 6

Step-by-step explanation:

We need to check the expressions that have value -\frac{1}{64}

Option A: (Negative one-fourth) cubed

(-\frac{1}{4})^3

Solving: (-\frac{1}{4})^3

We get -\frac{1}{64}

So, Option A is correct.

Option B: Negative (one-fourth) cubed

-(\frac{1}{4})^3

Solving: -(\frac{1}{4})^3

We get -\frac{1}{64}

So, Option B is correct

Option C: (Negative StartFraction 1 Over 8 EndFraction cubed

(-\frac{1}{8})^3

Solving: (-\frac{1}{8})^3

We get -\frac{1}{512}

So, Option C is not correct.

Option D: Negative (StartFraction 1 Over 8 EndFraction) squared

-(\frac{1}{8})^2

Solving: -(\frac{1}{8})^2

We get -\frac{1}{64}

So, Option D is correct.

Option E: (Negative one-half) Superscript 6

(-\frac{1}{2})^6

Solving:(-\frac{1}{2})^6

We get: \frac{1}{64}

So, Option E is not correct.

Option F: Negative (one-half) Superscript 6

-(\frac{1}{2})^6

Solving:-(\frac{1}{2})^6

We get: -\frac{1}{64}

So, Option F is correct.

So, correct Options are: Option A, B, D and F

Answer:

Each cupcake cost $2.50 and each brownie cost $2.00

Step-by-step explanation:

Let x represent the price of each cupcake and let y represent the price of each brownie.

Lily and Maddie bought one cupcake and one brownie for $4.50. Hence the equation is:

x + y = 4.50                (1)

Also Jessica purchased 3 cupcakes and one brownie for $9.50. Hence the equation is given by:

3x + y = 9.50              (2)

To find the price of each cupcake and brownie, we solve equation 1 and 2 simultaneously. To find x, subtract equation 1 from equation 2:

2x = 5

x = $2.50

Put x = $2.50 in equation (1):

2.50 + y = 4.50

y = $2.00

Therefore each cupcake cost $2.50 and each brownie cost $2.00

If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?
Burka [1]
y=kx \\ \\
y=144 \hbox{ when } x=12 \\
\Downarrow \\
144=k \times 12 \\
k=12 \\ \\
y=12x \hbox{ and }
x=17 \\
\Downarrow \\
y=12 \times 17 \\
y=204 \\ \\
\boxed{y=204} \hbox{ when } x=17

Solve the following system of equations. Show all work and solutions.
Hitman42 [59]
  • y=2x²+6x+1
  • y=-4x²+1

Make the equations equal and solve for x

  • 2x²+6x+1=-4x²+1
  • 6x²+6x=0
  • 6x(x+1)=0
  • 6x=0 or x+1=0
  • x=0 or x=-1

For x=0

  • y=-4(0)+1=1

For x=-1

  • y=-4(1)+1=-3

The solutions are

  • (0,1) and (-1,-3)
