Answer: A linear relationship
Step-by-step explanation:
From the graph we can see as the number of years increasing the average price of a PC decreasing at a constant rate.
It is forming a straight line and its equation
is similar to equation of line
, where m= -39 which is the rate of change of average price.
Hence, the relationship between the average price of PCs and the number of years that have passed since 2000 is a linear relationship.
Answer:
( 8 , - 8) => x² - 55 = 9
( 4 , - 4) => 2x² - 32 = 0
(5 , - 5) => 4x² - 100 = 0
(11 , - 11) => x² - 140 = -19
( 3, - 3) => 2x² - 18 = 0
Step-by-step explanation:
1)

x = ( 4 , - 4)
2)

x = ( 5 , - 5 )
3)

x= ( 8 , - 8)
4)

x = ( 11 , -11)
5)

x = ( 3 , - 3)
Answer:
C.
Step-by-step explanation:
you can automatically tell that it is C because the angles are a right angle together. A right angle is 90 degrees, which means that the angles together would be x=(4z-85)=90
