Answer: D (5/2, -17/4)
Step-by-step explanation: Using elimination your goal is to get rid or 1 variable so you can solve for the one that's left. By adding the -2y and 2y you will get 0. You will also add the 3x+x (4x) and -1+11 (10). You have now gotten rid of the y and have 4x=10. By dividing each side by 4 we now know x =2.5. D is the only possible solution with x=2.5 (5/2) but to solve for y you plug 2.5 in to an equation as x so) x-2y=11
2.5-2y=11
-2y=8.5 Answer D (5/2,-17/4) y=-17/4 (4.25)
6x²-5x+1
=6x²-3x-2x+1
=3x(2x-1)-1(2x-1)
=(3x-1)(2x-1)
Answer: -5, -7, and -9
Step-by-step explanation:
checking the pattern they are subtracting by two by the next term, so subtracting 2 from -3 would be -5 and so on.
<h3>
Answer: 18 miles</h3>
Reason:
The path is 2 miles and Randy walked it 13 times. He walked a total of 2*13 = 26 miles.
Carla walked the path 22 times, so she walked a total of 2*22 = 44 miles.
The difference of those results is 44-26 = 18 miles.
If you wanted to do the full calculation in one line, then it would be
2*22 - 2*13 = 18
or you could say
2*(22-13) = 18
Answer:
The answer for this is a=1,b=7,c=19.
