In plain and short, a function has no x-coordinate Repeats, if there's an x-coordinate Repeat, then is not a function.
When you add 20 and 29, you get 49. When you add 21 and 28, you get 49. You will realize that there's 5 pairs that result in a sum of 49. 5*49=245.
According to the problem's info, we have:
(1 + 2 + 4)pieces of fabric = 1bug
(7)pieces of fabric<span> = 1bug
</span>so we know for each bug Missy uses 7 pieces of fabric (of different shapes).
Then, if she uses 70 pieces (7*10) of fabric, those are 10 bugs(1*10) built.
so we have to multiply by 10 the amount of pieces used in one bug:
hexagonal = 1*10 = 10
rectangular = 2*10 = 20
triangular = 4*10 = 40
which give us 70 pieces total.
Answer:
A= width * height
A = (x+1)(x²-1) = x³-x+x²-1 =<em> </em>x³+x²-x-1
1st option is right one.
Answer:
m=0
Step-by-step explanation:
The slope of a line can be found using:
Let's call (2,0) our "2" coordinate, and (1,0) our "1" coordinate.
Coordinates are written as: (x,y)
Therefore, our x2 is 2 and y2 is 0. Our x1 is 1 and y2 is 0.
Substitute these values into the formula .
m=0
The slope of the line is 0
