Answer:

x = 1

Step-by-step explanation:

1/2x - 3/4 = 3/8 - 5/8x

The LCD is 8. Lets change every fraction to a denominator of 8.

4/8x - 6/8 = 3/8 - 5/8x

Now multiply both sides by 8.

4x - 6 = 3 - 5x

Add 5x to both sides. Add 6 to both sides.

9x = 9

Divide both sides by 9.

x = 1

Answer: x= 9/7

Step-by-step explanation: the numbers must have a common denominator which is 8. Multiply 1/2 by 4/4. Multiply -3/4 by 2/2. Since all numbers have 8 as their denominator, in parentheses, divide by 8. Then you will get 2x-6=3-5x. Add 5x to both sides. Then you will get 7x-6=3. Add 6 to both sides. Then you will get 7x=9. Divide by 7 to both sides. x= 9/7.

Answer:

1_11/20 pounds, or 1.55 pounds.

Step-by-step explanation:

Since at the beginning, he had 5 1/4 pounds and used 3/5, we subtract the amount of pounds. We are then left with 93/20 pounds, which he then splits among 3 containers. Dividing by three, we then get 31/20 pounds in one aquarium, or 1 11/20 pounds in each aquarium or 1.55 pounds.

Answer:

y = 3x+9

Step-by-step explanation:

We can use the slope intercept form

y = mx+b

where m is the slope and b is the y intercept

y = 3x +b

Substitute the point into the equation

6 = 3(-1) +b

6 = -3+b

Add 3 to each side

6+3 = -3+3+b

9 = b

y = 3x+9

Use logarithmic differentiation to find dy/dx
liq [111]

Answer:

dy/dx  =  (x^2 - 3)^sin x [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)]

Step-by-step explanation:

y = (x^2 - 3)^sinx

ln y = ln  (x^2 - 3)^sinx

ln y = sin x * ln (x^2 - 3)

1/y * dy/dx  =   sin x * {1 / (x^2 - 3)} * 2x + ln(x^2 - 3) * cos x

1/y dy/dx =  2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)

dy/dx  =   [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)] * y

dy/dx  =  (x^2 - 3)^sin x [2x sin x/ (x^2 - 3) + cos x ln(x^2 - 3)]
