Answer:
Do u need slope?
Step-by-step explanation:
Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
Answer:
Check attachment for the diagram
Step-by-step explanation:
Given two points A and B in the diagram attached, we see that exactly one line exists between these points.
Answer:
The center is (-4,-6) and the radius is 8
Step-by-step explanation:
(x+4)²+(y+6)²=64
The equation of a circle can be written in the form
(x-h)²+(y-k)²=r^2
Where (h,k) is the center and r is the radius
Rewriting the equation
(x - -4)²+(y- -6)²=8^2
The center is (-4,-6) and the radius is 8
