The height of a burning candle can be modeled by a linear function Candle A has an initial height of 201 millimeters ,and it’s height decreases 117 millimeters after 4 hours of burning . The height ,h , h = 290-5t , where t is the time in hours . Which of the following statements is true ? The initial height of Candle A is greater than the initial height of Candle B
The height of Candle A decreases at a faster rate than the height of Candle A
Candle B will burn out in 58 hours
After 10 hours , the height of Candle A is 110 millimeters
Candle A will burn out before Candle B

Its d so thats how it would would back from 1.0 form three four two

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
