If quadrilateral 1 is reflected across the x-axis and translated 8 units down to form quadrilateral 2, which statement is true?

Answer:

(A) Quadrilateral 1 is congruent to quadrilateral 2 because the transformations are rigid.

Step-by-step explanation:

This is because since it's only being reflected across the y-axis and translated 8 units down, it's still an isometric.

Isometry or rigid transformation is the opposite of a non-rigid transformation and occurs during translations, reflections and rotations. Non-rigid transformations occur in dilations.

Isometry basically keeps all measure angles and distances of the polygon the same before and after a transformation.

Find the x and y intercepts for the following equation. 2x– 7y=-14
Kisachek [45]

Answer:

C: Xint = 2, Yint. = -7

Step-by-step explanation:

Given the equation, 2x - 7y = -14:

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0.  To solve for the y-intercept, set x = 0:

2x - 7y = -14

2(0) - 7y = -14

0 - 7y = -14

-7y = -14

Divide both sides by -7 to solve for y:

-7y/-7 = -14/-7

y = 2

Therefore, the y-intercept = 2.

Next, the x-intercept is the point on the graph where it crosses the x-axis, and has coordinates, (a, 0). To find the x-intercept, set y = 0 and substitute into the given equation:

2x - 7y = -14

2x - 7(0) = -14

2x - 0 = -14

2x = -14

Divide both sides by 2 to solve for x:

2x/2 = -14/2

x = -7

x-intercept = -7.

Therefore, the correct answer is C: Xint = 2, Yint. = -7

5 (i + 2) = 8 (i -1)
Vinil7 [7]
5(i + 2) = 8(i -1)
5i + 10 = 8i -8
-3i + 10 = -8
-3i = -18
