Lets factor 8x^2 - 10x - 25
= 8x^2 -20x + 10x - 25
= 4x(2x - 5) + 5(2x - 5) 2x-5 is common to both parts so factors are:-
= (4x + 5)(2x - 5)
So its C
Answer: 5%
Step-by-step explanation:
100% - 40%
= 60% or 3/5 - first day
2/5 of 3/5 = 6/25 = 24% eaten
36% left - 2nd day
2/5 of 6/25 = 14.4% eaten
= 21.6 % left - 3rd day
2/5 of 21.6 = 8.64% eaten
= 12.96 % left - 4th day
2/5 of 12.96% = 5.184 eaten
= 7.776% left - 5th day
2/5 of 7.776% = 3.1104% eaten
= 4.6656% left after the 6th day
rounded off to 5% after the 6th day

Step-by-step explanation:
If they give you a point and slope, use point slope form.
Then simplify to get slope intercept form (y = mx + b)
slope (m) = 5
(-2, 1)
y - y1 = m(x - x1)
y - 1 = 5(x + 2)
y - 1 = 5x + 10
y = 5x + 11
Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.
