B - 7x = a - b
Subtract b from both sides.
-7x = a - 2b
Divide both sides by -7.
x =
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points
and
is given by,
Slope = 
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope = 
= (-1)
Therefore, slope of the line is (-1).
The answer would be A. -16
The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is 
Step-by-step explanation:
We need to find a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3.
If -1, 1 and 3 are real zeros, it can be written as:
x= -1, x= 1, and x = 3
or x+1=0, x-1=0 and x-3=0
Finding polynomial by multiply these factors:

So, The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is
