Answer:
Summer is incorrect
Step-by-step explanation:
It definitely matters which side is side "c". Side "c" must be the hypotenuse (the side across from the right angle).
The other two sides are the legs (sides touching the right angle), and either leg can be "a" or "b", but the hypotenuse must be "c".
Take the equation, a² + b² = c², and subtract c² from both sides:
It won't matter which leg is "a" or "b", because of the commutative property of addition. Note that "a²" and "b²" are added together, and due to the commutative property of addition, we can add in either order and get the same result.
However, since the c² term is connected by subtraction, and subtraction doesn't have a commutative property, it can't be subtracted in any order. Meaning which side it is is important.
Answer:
1. n + 8 = 10
2. = 10
3. 8n - 6 = 34
4. 3(n + 12) = 45
5. No
6. Yes
Step-by-step explanation:
(only for questions 5 and 6)
5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.
6. If you substitute in b = 8, you get:
this is true.
Answer:
see below
Step-by-step explanation:
A cubic with a positive leading coefficient will have a general trend of upward to the right. (If the leading coefficient is negative, it will trend downward.) If there is only one real zero, it will cross the x-axis exactly once. There may or may not be two turning points, but there won't be any more than that. (There may be no turning points.)
The attached graph shows a couple of examples. The turning points and inflection points may be on either side of the x-axis.
