Answer:

Step-by-step explanation:
I'm going to write it so I can see it better:

You can use the difference of squares formula:

Answer:
Residual = Observed Value - Predicted Value
A residual plot is a graph that shows the residual values in the vertical axis and the independent variable or values of x in the horizontal axis. So the coordinates would be (x, corresponding residual of x)
The points in a residual plot of the data based on the table will be:
(1,-0.4)
(2,0,7)
(3,-0.2)
(4,-0.6)

Answer:
3)x=7,y=-2
Step-by-step explanation:
Multiply numerator and denominator by the conjugate of the denominator
Denominator: -10 + 8i
Conjugate of the denominator: -10 - 8i
Operation:
[9 +7i] / [-10 + 8i] * [-10 -8i] / [-10 - 8i] = [-90 - 72i - 70i +56] / [100 + 64] =
[-34 -142i] / 164 = [-17 -71i] / 82
Answer:
It would be $9.
Because 60 * 0.15 = 9
