30% off an item would make that item valued at 70% of its original price
94 times 0.7 = 65.8

Plug in 1 for n and solve, then plug in 2, and so on until you get to 3(6)-1=17
I use it as a short way to say "okay" but I don't know how others may use it.
Step-by-step explanation:
Y=-4x+3
2x+3y=19
2x+3(-4x+3)=19
2x-12x+9=19
-10x=10
X=-1
y=-4*(-1)+3=4+3=7
x=-1 y=7
Let the radius of the circle be r. Then the line from the external point through the center of the circle which extends to the far point on the circle has length 3r .By the tangent - secant theorem
t^2 = 3r * r = 3r^2 ( where t is the length of the tangent).
So t = √(3r^2) = √3r answer.
