after using the linear regression feature on my calculator I have estimated that a car 8 years after being purchase would have a value of about $5,404.66
Answer: 30°, 67° e 83°.
Step-by-step explanation: The angles are (2x + 16)/5 , x e x + 16°
Adding all the angles, comes:
(2x + 16)/5 + x + x + 16° = 180° ;
2x + 16° + 5x + 5x + 80° = 900° ;
12x = 900° - 16° - 80° ;
12x = 804°° ;
x = 804°/12 ;
x = 67°
So, the first angle is (2,67 + 16)/5 = 30°, the second is 67° and the third is 83°.
It would be a right scalene triangle.
hope this helped :)
Domain = -4<=x<=5
Range = -4<=y<=4
Yes it is a function because each input maps to exactly one output.
