Answer:

Step-by-step explanation:
4-xy=y^3
dy/dx=?

Solving for dy/dx: Addind x dy/dx both sides of the equation:

Common factor dy/dx on the right side of the equation:

Dividing both sides of the equation by 3y^2+x:

Answer: 
Step-by-step explanation:
By the negative exponent rule, you have that:

By the exponents properties, you know that:

Therefore, you can rewrite the left side of the equation has following:

Descompose 32 and 8 into its prime factors:

Rewrite:

Then:

As the base are equal, then:

Solve for x:

.76 cents per cup.
Their are 16 cups in a gallon.
2 gallons would be 32cups.

21:26:38
Step-by-step explanation:
Ratio in mathematics is the relationship between two or more amounts, showing how many times they can be contained in one another.
Example: 1:2 means there are two times the first amount in the second.
For the case above;
Given;
Number of each shape noah drew;
hearts = 26
Stars = 21
circles = 38
The ratio of stars to hearts to circles
N(stars) : N(hearts) : N(circles)
21:26:38
Since they are not divisible by a common factor the ratio remains;
