You can prove a triangle is isosceles by finding the amount of right angles in a triangle. A triangle containing 2 right angles is classified as isosceles.
Don’t know sorry I need point
2(x + 3) = 18
2x + 6 = 18
- 6 =
2x = 12
Divide 2
x = 6
Answer:
The domain of the relation is ![[(5,16,18,21]](https://tex.z-dn.net/?f=%5B%285%2C16%2C18%2C21%5D)
Step-by-step explanation:
we have
![[(15,65),(21,70),(18,73),(16,62)]](https://tex.z-dn.net/?f=%5B%2815%2C65%29%2C%2821%2C70%29%2C%2818%2C73%29%2C%2816%2C62%29%5D)
Remember that
The domain of the relation are the values of x
The range of the relation are the values of y
therefore
The domain is
![[(5,21,18,16]](https://tex.z-dn.net/?f=%5B%285%2C21%2C18%2C16%5D)
order them from lowest to highest -------> ![[(5,16,18,21]](https://tex.z-dn.net/?f=%5B%285%2C16%2C18%2C21%5D)
The range is
![[65,70,73,62]](https://tex.z-dn.net/?f=%5B65%2C70%2C73%2C62%5D)
order them from lowest to highest ------->![[62,65,70,73]](https://tex.z-dn.net/?f=%5B62%2C65%2C70%2C73%5D)
All you have to do is find the total amount he wrote out checks for and then subtract that from $259.68. The answer is $99.03
