the answer would be -10,4 because when something is reflected over the y axis the x-value becomes the opposite sign. when something is reflected over the x-axis then the y-value becomes the opposite

Answer:

(10, 4)

Step-by-step explanation:

The easiest way to understand it is to draw it. Please notice that the distance from Y axis is still 4, the point is just at the other side of the axis.

Square has a side length of (x-5). If the perimeter is 24, what is the<br> value of x? *
san4es73 [151]

Answer:

11 units

Step-by-step explanation:

<em>hey there,</em>

<em />

< A square has 4 sides that are all always equal to each other. The perimeter is all the sides summed up together. That means (for example), if one side of the square is 2 cm, then we know that the perimeter is 8 cm, because 2 + 2 + 2 + 2 = 8 (or 2×4=8).

Here we are given that one side is equal to "x-5". Pretend that is a number and solve as I did just right above:

(x-5)×4 = 4x -20

Now we know that the perimeter is (4x-20) units (when you don't know what the units are then just put "units").

We also know that the perimeter can be a number which is 24. That means these two values are equal to each other.

4x-20 = 24

Now solve! Bring x to one side, and all the numbers to the other side.

4x = 44

x = 11

We now know that the value of one side of the square (x) is equal to 11 units. >

Help?
Kazeer [188]
Remember, h(x) = y and x ...well, x is x...lol

B. h(x) = |x|....subbing in (-1,1)
     y = |x|
     1 = |-1|...absolute values are positive, even when they say negative
     1 = 1 (correct)
