Step-by-step explanation:
Answer:
The radius of the aquarium tank is 
Step-by-step explanation:
we know that
Applying the Tangent Secant Theorem

we have that


substitute


Solve for D



Find the radius
The radius is half the diameter

The system won't have a unique solution when what appears to be two lines is really only one line. The coefficients in an equation for a line only matter in ratio; if we multiply them all by the same non-zero scalar we'll still have the same line, of course with an infinite number of points on it, our infinite number of solutions.
2x - y = 8
6x - 3y = 4a
We need these to be the same equation, meaning they have to have all the same solutions. So we have to figure out the factor to multiply the first equation by to get the second.
That factor is obviously 3 because 3(2x)=6x and 3(-y)=-3y. So we need the constants in the same ratio,
3(8) = 4a
24 = 4a
a = 6
Answer: B. 6
-15, -7, -4, 0, 3
because you have to remember that the bigger the negative number, the less it's worth because it's getting farther and farther away from positive numbers
