Step-by-step explanation:
3(x - 4y) - 2(y + 7x)
= 3x - 12y - 2y - 14x
= 3x -14x -12y -2y
= -11x -14y
Answer:
Step-by-step explanation:
The slope represents how much y is predicted to change on average for each 1 unit in x.
y = appraised value of a house in East Meadow County
x = # of rooms
1 unit of x = 1 additional room
1 unit of y = $1,000
slope = 19.79
Answer: Each additional room in a house in East Meadow County is predicted to increase the appraised value by 19.79 x $1,000 = $19,790, on average.
Note: Since we only sampled homes in East Meadow County, our regression equation is only good to predict appraised values in that county. So, our interpretation must include that fact.
X-2/x+1 i think i’m not sure of that
