Answer:

l(x,y) = (-4y, -4x - 3)

Step-by-step explanation:

Let's start with function (x, y)

Transformations in the given order result in following

A dilation by a factor of 4 with the origin as the center of dilation

This results in both coordinates multiplied by 4
(x, y) → (4x, 4y)

A reflection across the y-axis

This results in x-coordinate changing sign to opposite
(4x, 4y) → (-4x, 4y)

A 90° counterclockwise rotation about the origin

This results in x-coordinate swapping with negative y-coordinate
(-4x, 4y) → (-4y, -4x)

A translation 3 units down

This results in y-coordinate change by -3
(-4y, -4x) → (-4y, 4x - 3)

The final function is:

l(x) = (-4y, -4x - 3)

Solve Ax − By = C for x.

Travka [436]

For this case we have the following equation:

$Ax - By = C$

From here, we must clear the value of x.

Adding By on both sides:

$Ax = By + C$

Then, dividing both sides by A we have:

$x = \frac {By + C} {A}$

Answer:

$x = \frac {By + C} {A}$

x equals the quantity B times and plus C all over A
