makkiz [27]

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of an object.

Given the vertex matrix of quadrilateral ABCD as:

\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right]

Therefore the vertex of quadrilateral ABCD is at A(-1, 2), B(5, 5), C(5, 3) and D(-4, -1).

Quadrilateral ABCD is dilated by a scale factor of 3 to produce quadrilateral A'B'C'D'.

Hence, the vertex matrix of quadrilateral A'B'C'D' is:

3\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right]=\left[\begin{array}{cccc}-3&15&15&-20\\6&15&9&-3\end{array}\right]

Therefore the vertex of quadrilateral A'B'C'D' is at A'(-3, 6), B'(15, 15), C'(15, 9) and D'(-20, -3).

The correct option is figure A

Solve for x 11x+4<15 OR 12x−7>−25
never [62]

Isolate the x in both cases. What you do to one side, you do to the other.


11x + 4 < 15


Subtract 4 from both sides


11x + 4 (-4) < 15 (-4)


11x < 11


isolate the x, divide 11 from both sides


11x/11 < 11/11


x< 1


x < 1 is your answer for the first one

-------------------------------------------------------------------------------------------------------------------


Again, isolate the x.


12x - 7 > -25


Add 7 to both sides


12x - 7 (+7) > -25 (+7)


12x > -18


Isolate the x, divide 12 from both sides


12x/12 > -18/12


x > -1.5 is your answer for the second one.
