The image of a figure is shown. What are the coordinates of X in the pre-image of the figure if the rule that created the image
nydimaria [60]

The coordinates of X in the pre-image of the figure is (3.2, 0.6) if the  transformation rule is T_(-5.2, 1.4)(x, y)

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we can see in the figure.

The transformation rule is T_(-5.2, 1.4)(x, y)

X'(-2, 2)

Before the transformation:

X = (-2+5.2, 2-1.4)

X = (3.2, 0.6)

Thus, the coordinates of X in the pre-image of the figure is (3.2, 0.6) if the  transformation rule is T_(-5.2, 1.4)(x, y)

Can someone please help I really don’t understand this please explain.
marta [7]

Answer:

The answer is option D.

Step-by-step explanation:

You have to multiply it :

h(x) × g(x) = (h×g)(x)

(h×g)(x) = (x² + 2x)(-3x + 4)

(h×g)(x) = -3x³ + 4x² - 6x² + 8x

(h×g)(x) = -3x³ - 2x² + 8x

2x2-3x-2=x+4 select all the solutions
Papessa [141]
Solve for x over the real numbers:2 x^2 - 3 x - 2 = x + 4
Subtract x + 4 from both sides:2 x^2 - 4 x - 6 = 0
The left hand side factors into a product with three terms:2 (x - 3) (x + 1) = 0
Divide both sides by 2:(x - 3) (x + 1) = 0
Split into two equations:x - 3 = 0 or x + 1 = 0
Add 3 to both sides:x = 3 or x + 1 = 0
Subtract 1 from both sides:Answer:  x = 3 or x = -1
