Answer:

$\frac{4^{21}}{5^6}$

Step-by-step explanation:

$\left(\frac{4^7}{5^2}\right)^3$

$=\frac{\left(4^7\right)^3}{\left(5^2\right)^3}$

$\left(4^7\right)^3$

$=4^{21}$

$=\frac{4^{21}}{\left(5^2\right)^3}$

$\left(5^2\right)^3$

$5^6$

$=\frac{4^{21}}{5^6}$

Solve liner equation for they variable<br> 3x-5(x+6)=-2x-2(5+10)

Dvinal [7]

Answer:

all numbers

Step-by-step explanation:

3x - 5(x + 6) = -2x -2(5 + 10)

Distribute on both sides.

3x - 5x - 30 = -2x - 10 - 20

Add 2x to both sides.

-2x - 30 = -2x - 30

-30 = -30

Since we get a true statement after only doing legal steps to solve the equation, the equation has an infinite number of solutions.

Does anyone get this ? if so can u lmk the answer thxxxx:)

Given:

In parallelogram ABCD, two of its vertices are A(-4,0) and B(0,3).

To find:

The equation that represents a line that contain CD.

Solution:

We have,

A(-4,0) and B(0,3)

Slope of AB is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{3-0}{0-(-4)}$

$m=\dfrac{3}{4}$

The slope of line AB is $\dfrac{3}{4}$ .

Opposite sides of a parallelogram are parallel and slopes of parallel lines are equal.

In parallelogram ABCD, AB and CD are opposite sides. So, their slopes must be equal.

Slope of line AB = Slope of line CD = $\dfrac{3}{4}$

The slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

Slope of line CD is $\dfrac{3}{4}$ , it means the line must be of the form

$y=\dfrac{3}{4}x+b$

Coefficient of x is $\dfrac{3}{4}$ only in option a.

Therefore, the correct option is a.
