Answer:
3y-4x=9
Step-by-step explanation:
using y-y1/ x- x1=m
y-1/x--3=4/3
y-1/x+3= 4/3
3(y+1)=4(x+3)
3y+3= 4x+12
3y-4x=12-3
3y-4x=9
Answer:
its 2(x-4)
Step-by-step explanation:
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.
The answer should be a, 45
Answer:
b and d
Step-by-step explanation:
Sum = 4
Product = -32
Factors = 8 , (-4)
x² + 4x - 32 = x² + 8x - 4x - 4*8
= x(x + 8) - 4(x + 8)
= (x + 8)(x - 4)
