Answer:
Step-by-step explanation:
i think you are talking about the diameter of the circle.
equation of the circle is
(x-1)(x+3)+(y-8)(y-2)=0
x^{2}-x+3x-3+y^{2}-8y-2y+16=0
or x^{2}+y^{2}+2x-10y+13=0
Answer:
Step-by-step explanation:
The volume of a sphere is (4/3)πr^3, where r is he radius.
Given r=7,
(4/3)π7^3=(4/3)π*343=(457 1/3)π
Answer:
The height is 0 when it "drops".
3/2x + 9 = 0
3/2x = -9
3 = -9(2x)
3 = -18x
3/-18x
Change signs, time cant be negative.
x= 6
Another interpretation; Slope is negative it is falling. This interpretation is more accurate.
-3/2x + 9 = 0
-3/2x = -9
-3 = -9(2x)
-3 = -18x
6 = x

Answer:
The system of equations has one solution at (-4, 4).
Step-by-step explanation:
We are given the system of equations:
We can use elimination to solve this system. We need to multiply the second equation by -5 so we can cancel out our x-terms.
Therefore, our system now becomes:
Now, we can add these two equations together and solve for y.
Now, we can substitute our value for y into one of the equations and solve for x.
Therefore, our final solution is (-4, 4).
