Answer:
66
Step-by-step explanation:
B is 57
C is 57
180 - (57 x 2) =
180 - 114 = 66
Answer:
1. The given equation does not have root at x = - 3.
2. (x - 3) (x + 1) (x² + 4) = 0
This curve will intersect twice the x-axis.
Step-by-step explanation:
1. If the right hand side of the equation
......... (1) becomes same as the left hand side by putting x = - 3, then only we can conclude that x = - 3 is a root of the equation.
But in this case
.
Therefore, x = - 3 is not a root of the above equation (1).
2. The equation of the polynomial with roots 3, -1, 2i, and -2i is
(x - 3) (x + 1) (x - 2i) (x + 2i) = 0
⇒ (x - 3) (x + 1) (x² + 4) = 0 (Answer)
Therefore, the graph of the above curve will intersect twice the x-axis in a real coordinate plane, at x = 3 and at x = -1. (Answer)

Step-by-step explanation:
Answer:
Slope is defined as the difference in the vertical axis divided by the difference in the horizontal axis, going left to right (s = dy/dx). P has a lesser x co-ordinate, so it will be R - P in this case, giving us (ry - py) / (rx - px):
![s = \frac{{\Delta}y}{{\Delta}x}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B%7B%5CDelta%7Dy%7D%7B%7B%5CDelta%7Dx%7D)
![s = \frac{73 - 9}{57 - 4}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B73%20-%209%7D%7B57%20-%204%7D)
![s = 64/53](https://tex.z-dn.net/?f=s%20%3D%2064%2F53)
