aleksley [76]
For this case we have the following equation:
 V = I * R
 Where,
 V: voltage
 I: current
 R: resistance
 By clearing R we have:
 R = V / I
 Substituting the values:
 R = (20) / (0.57)
 R = 35.09 Ohms
 Answer:
 
The resistance of the light bulb is:

- (x + 2)2 + (y - 9)2 = 1
telo118 [61]

Answer:

x+y=-5.75

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, you would simply need to use the distributive property!

-(2)x-(2)2+(2)y-(2)9=1

-2x-4+2y-18=1

Then you need to add/subtract so the similar numbers are together.

-2x+2y-22=1

-2x+2y=23

x+2y=-11.5

x+y=-5.75
