Well <span>(x, y)→(−x, y) </span>means it's reflected off the y-axis(You can experiment this with random points on a graph)
(x, y)→(x−1, y+2) means that every point is moved to the left by 1 and up by 2, in other words, the triangle is translated left 1 up 2.
Since the only thing that effects congruency is dilation(rotation, translation, and reflection only move the shape, not change it), The new triangle should equal the old one.
Thus we would get the first choice

3 is greater than x, and -2 is less than x<br>sex only once in your inequality.​
VladimirAG [237]

Answer:

-2

Step-by-step explanation:

Question:

3 is greater than x, and -2 is less than x

Use x only once in your inequality.​

Solution:

Given inequalities:

3 is greater than x is represented as 3>x

-2 is less than  x is represented as -2

In order to write the compound inequality we put x in the middle and set up the inequalities as per the constraints.

Thus, the compound inequality can be given as:

-2

Thus, by using x only once we can represent the given inequities.

The diagonals of a rhombus are 21 m and 32 m. What is the area of the rhombus?<br> 30 POINTS
Wittaler [7]
I have included attachment below

so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2

answer is 336 m^2

S² = 3V / H
Ganezh [65]

The "opposite operation" of squaring is taking a square root.

The equation then gets translated S=\sqrt{3\frac{V}{H}}.

Hope this helps.
