Answer:
Quadrant III
Step-by-step explanation:
Use u subsitution the solve by grouping
u=x^2
u^3-16u=4u^2-64
u^3-4u^2-16u+64=0
(u^3-4u^2)+(-16u+64)=0
u^2(u-4)+(-16)(u-4)=0
(u^2-16)(u-4)=0
(u-4)(u+4)(u-4)=0
(u+4)(u-4)^2=0
u=x^2
(x^2+4)(x^2-4)^2=0
(x^2+4)((x-2)(x+2))^2=0
(x^2+4)(x-2)²(x+2)²=0
set to zero
x^2+4=0
x^2=-4
x=+/-2i
x-2=0
x=2
x+2=0
x=-2
the other roots are -2 and 2

Answer:
1) Mutually exclusive
2) Overlapping or inclusive
Answer:
b = 1
Step-by-step explanation:
5 = 5b
b = 1
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
The initial value is the y-intercept, or it's like the starting point.
If the equation has an initial value of 10, b = 10
Your answer is the 2nd option because the y-intercept is 10
