A shop sells three brands of light bulb. Brand A bulbs last for 760 days each. Brand B bulbs last for 690 days each. Brand C bulbs last for 720 days each. Calculate the cost of 1 day's use for 1 bulb in each brand. Give your answers in pence to 3 dp.

correct answer:

i^31 = -i

c

step-by-step explanation:

i think because what else can be a sample of every member

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
