Answer: (-2,-4)

Step-by-step explanation:

To find the midpoint between two points we need to find the mean average between the x and the y .

Since we know the midpoint will have to represent the missing coordinates by the variables.

$\frac{-6+x}{2} = -4$ Solve for x to find the x coordinate by first multiplying both sides by -4.

-6 + x = -8 Add -6 to both sides

+6 +6

x = -2

The x coordinate of the B is -2 now we need to find the y coordinate.

$\frac{4+y}{2} = 0$ Multiply both sides by 2

4 + y = 0 Subtract 4 from both sides

-4 -4

y = -4

The y coordinate is -4 so the coordinates will be (-2,-4)

If 20% of a number p is 10, what is 10% of p?

kobusy [5.1K]

Answer:

Step-by-step explanation:

20% of p = 10

20% = 0.2

Multiply

0.2p = 10

Multiply both sides of the equation by 5

p = 50

Find 10% of p

10% = 0.1

Multiply

0.1(50)

10% of p is 5

Hope this helps :)

Find dy/dx for 4 - xy = y^3

storchak [24]

Answer:

$\frac{dy}{dx}=-\frac{y}{3y^2+x}$

Step-by-step explanation:

4-xy=y^3

dy/dx=?

$\frac{d(4-xy)}{dx}=\frac{d(y^3)}{dx}\\ \frac{d(4)}{dx}-\frac{d(xy)}{dx}=3y^{3-1}\frac{dy}{dx}\\ 0-(\frac{dx}{dx}y+x\frac{dy}{dx})=3y^2\frac{dy}{dx}\\ -(1y+x\frac{dy}{dx})=3y^2\frac{dy}{dx}\\ -(y+x\frac{dy}{dx})=3y^2\frac{dy}{dx}\\ -y-x\frac{dy}{dx}=3y^2\frac{dy}{dx}$

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

$-y-x\frac{dy}{dx}+x\frac{dy}{dx}=3y^2\frac{dy}{dx}+x\frac{dy}{dx} \\ -y=3y^2\frac{dy}{dx}+x\frac{dy}{dx}$

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

$-y=(3y^2+x)\frac{dy}{dx}$

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

$\frac{-y}{3y^2+x}=\frac{(3y^2+x)}{3y^2+x}\frac{dy}{dx}\\ -\frac{y}{3y^2+x}=\frac{dy}{dx}\\ \frac{dy}{dx}=-\frac{y}{3y^2+x}$

Apply Laws of Exponents to write an equivalent expression.<br> (3y)-4. (2z)-4

Stels [109]

After Applying Laws of Exponents we can write as $(6yz)^{-4}$

<h3>What is law of exponents ?</h3>

The exponent of a number indicates how many times a number has been multiplied by itself. For instance, 34 indicates that we have multiplied 3 four times. Its full form is 3 3 3 3. Exponent is another name for a number's power. A whole number, fraction, negative number, or decimal are all acceptable.

<h3>How are powers of powers multiplied?</h3>

Exponents with distinct bases and the same powers can be multiplied by multiplying the bases and writing the power outside of the brackets.

$a^{n}$ . $b^{n}$ = $(a.b)^{n}$
