Answer:
345 km
Step-by-step explanation:
9 divided by 3 = 3
115 x 3 = 345
Answer:
3
X is slope but the equation isnt set up proper
12x-4y=3
-12x -12x
-4y=-12x+3
/-4 /-4
y= 3x+3/-4
The answer: the second one y= -2x+7
Answer:
y = 3.5X - 6921.2
Step-by-step explanation:
Given the data :
X :
1990
1992
1994
1996
1996
Y :
45
51
57
61
75
Using an online regression calculator ; the regression model obtained is : y = 3.5X - 6921.2
Where ; slope = 3.5 ; intercept = - 6921.2
