Answer:
x > 3
Step-by-step explanation:
Given 2 sides of a triangle then the third side x will be
difference of sides < x < sum of sides , that is
15 - 12 < x < 15 + 12, so
3 < x < 27
Thus x > 3
Answer:
"first"
Step-by-step explanation:
The only variable is x, and this x is to the first power. So the degree of this poly is "first."
Answer:
1) yes
2) No
3) No
4) yes
5) No
Step-by-step explanation:
1) f(0)=0, f(1)=1, f(2)=2, f(3)=3, then ![f[\{0, 1, 2, 3\}]=\{0, 1, 2, 3\}](https://tex.z-dn.net/?f=f%5B%5C%7B0%2C%201%2C%202%2C%203%5C%7D%5D%3D%5C%7B0%2C%201%2C%202%2C%203%5C%7D)
2) f(0)=0, 
, then f(1)=1; 
, then f(2)=0; 
, then f(3)=1
Then ![f[\{0, 1, 2, 3\}]=\{0, 1, 3\}](https://tex.z-dn.net/?f=f%5B%5C%7B0%2C%201%2C%202%2C%203%5C%7D%5D%3D%5C%7B0%2C%201%2C%203%5C%7D)
, this means that f isn't onto.
3.
, then f(1)=0
, then f(2)=2
, then f(3)=2
Then ![f[\{0, 1, 2, 3\}]=\{0, 2\}](https://tex.z-dn.net/?f=f%5B%5C%7B0%2C%201%2C%202%2C%203%5C%7D%5D%3D%5C%7B0%2C%202%5C%7D)
, this means that f isn't onto.
4. ![f[\{0, 1, 2, 3\}]=\{0, 1, 2,3\}](https://tex.z-dn.net/?f=f%5B%5C%7B0%2C%201%2C%202%2C%203%5C%7D%5D%3D%5C%7B0%2C%201%2C%202%2C3%5C%7D)
, then f is onto.
5. ![f[\{0, 1, 2, 3\}]=\{1, 2\}](https://tex.z-dn.net/?f=f%5B%5C%7B0%2C%201%2C%202%2C%203%5C%7D%5D%3D%5C%7B1%2C%202%5C%7D)
, this means that f isn't onto.
Answer:
y=-35
Step-by-step explanation:
The relationship between the values of x and y is multiplying by -5.
Therefore, when x equals 7, y is -35.
