Step-by-step explanation:
Find the measure of an exterior angle of a regular decagon.
40 degrees.
Answer:
(- 1, 4 )
Step-by-step explanation:
x = 1 is a vertical line passing through all points with an x- coordinate of 1
The point P(3, 4) is to units to the right of x = 1.
Hence the refection will be 2 units to the left of x = 1
P' = (1 - 2, 4 ) = (- 1, 4 )
The perimeter of a rectangle is 2(w+l)
We can find the lengths by setting the equation equal to 12.
12=2(w+l)
12÷2=(2(w+l))÷2
6=w+l
6=1+5
6=2+4
6=3+3
These are the lengths of the sides of three rectangles with a perimeter of 12 units.
You're probably wondering why the third one has two of the same number, because that's usually how the lengths of sides of squares are, not rectangles.
Well, there's this wonderful thing about the rules of shapes.
<em>Squares ARE rectangles.
</em>Because they follow the rules for a rectangle, squares are also classified as rectangles.
So, the rectangle side lengths are as follows:
1 unit by 5 units
2 units by 4 units
3 units by 3 units

Answer: zero slope
Explanation: The equation y = -4 can be thought of as y = 0x - 4.
So our line has a slope of 0 and a y-intercept of -4.
This line is a flat line or horizontal.
In fact, when the equation of any line reads y = <em>a number</em>, its slope
will always be 0 because it's a horizontal line.
So, this line has a slope equal to <em>zero</em>.
