The three angles are 36 , 72 and 72.
Answer: First, Third and Fourth options are correct.
Step-by-step explanation:
As we know that Rational numbers are those numbers which can be positive integers, negative integers and can be written in the form of p/q i.e. in fractions.
So, it is true for positive integers
It is true for negative integers.
It is true for fractions.
Hence, First, Third and Fourth options are correct.
Answer:
<u>Part A</u>
- Reflect over the y-axis: (x, y) → (-x, y)
A (-4, 4) → (4, 4)
B (-2, 2) → (2, 2)
C (-2, -1) → (2, -1)
D (-4, 1) → (4, 1)
- Shift 4 units down: (x, y-4)
(4, 4-4) → A' (4, 0)
(2, 2-4) → B' (2, -2)
(2, -1-4) → C' (2, -5)
(4, 1-4) → D' (4, -3)
<u>Part B</u>
Two figures are <u>congruent</u> if they have the same shape and size. (They are allowed to be rotated, reflected and translated, but not resized).
Therefore, ABCD and A'B'C'D' are congruent. They are the same shape and size as they have only be reflected and translated.
Answer: undefined
Step-by-step explanation:
The answer is undefined because when you plug in the points in the formula
y2-y1/ x2-x1 the denominator is 0 which makes it undefined. Also when you put it into a graphing calculator it will say that its undefined.
Answer:
24 books
Step-by-step explanation:
Initially the top shelf has no books placed on
Then books added to this:
And now all 4 shelves have same amount of books. So total number is:
