ANSWER:

On solving equation, we get

3x - y = 12
3x = 12 + y
x = 12 + y/3 ...(1)

We have to find,

8^x/2^y
2^3x/2^y
2^3x - y

Plugging the value of x,

2^3(12 + y/3) - y
2^12 + y - y
2^12
4096

Hence, The value of 8^x/2^y is 4096.

WILL MARK THE BRAINLIEST!! What are the amplitude, period, phase shift, and midline of f(x) = 2 sin(x + π) − 4?

xxMikexx [17]

Answer:

Step-by-step explanation:

Amplitude is twice the coefficent of the sine function. In this case, $2*2=4$

Period is $2\pi$ divided by the coefficent of x, in this case, $\frac {2\pi} 1 =2\pi$

Phase shift, is how much you sum or subctract from x inside the sine, in this case $\pi$ .

Midline you get by hiding the sine and reading what's left, in this case, -4.

Answer:

Step 1 Divide all terms by a (the coefficient of x2).

Step 2 Move the number term (c/a) to the right side of the equation.

Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

A recipe for cake needs 3/4 if a cup of milk. you are making 1/2 of the recipe.his much milk do you need

r-ruslan [8.4K]

I would say it's 3/8 of a cup because if you multiply 3/4 by 2 it would be 6/8. It's the same amount but just a different measurement. Now just take 3 away from 6/8 and you have 3/8 which is half of 3/4.

What is the answer please help me

Rom4ik [11]

Answer:

700 miles

Step-by-step explanation:

Since the scale is 0.5 and she's 7 inches away on the map, you divide 7 by 0.5 and get 14. Then, you multiply 14 by 50 because each inch is 50 miles.
