Would you rather have your debit card declined if you don't have enough
Sedbober [7]
I’d rather have my card declined because then i won’t overspend money that i dont have. The only exception would be an emergency for someone close to me or something along those lines.

If you have any more questions feel free to ask in the comments!

Hope this helps!!!

Three circles with centers A, B, and C are externally tangent to each other as shown in the figure. Lines EG and DG are tangent
fiasKO [112]
My solution to the problem is as follows:

EC = 15 ... draw CF = 6 (radius) ...use Pythagorean theorem to find EF. 

EF^2 + CF^2 = EC^2 
EF^2 = 15^2 - 6^2 = 189 .... EF = sq root 189 

triangle GDE is similar to CFE ... thus proportional 
GD / ED = CF / EF 
GD / 18 = 6 / (sq root 189) 
<span>GD = 108 / (sq root 189)

I hope my answer has come to your help. God bless and have a nice day ahead!

A) x + y = 17
B) x * y = -308

B) y = -308 / x Substituting this into A)
A) x -308 / x = 17
A) x^2 -308 = 17x
A) x^2 -17x -308 = 0
x = 28
y = -11
