Answer:
B and R
I think that is the name of the lines. If not the the first two lines!!!!
I'm pretty sure it would be <span>x - y + 1 = 0 because if you plug in one of the coordinates into each equation, this is the only one that works.
</span><span>y - x + 1 = 0
2 - 1 + 1 = 0
2 = 0 not correct
</span><span>x - y + 1 = 0
1 - 2 + 1 = 0
0 = 0 correct
</span><span>-x - y + 1 = 0
-1 - 2 + 1 = 0
-2 = 0 not correct
</span>
CONSECUTIVE NUMBERS; x, x+1
(x+1)4=3(x)+23
4x+4=3x+23
4x-3x=23-4
x=19
x+1=20
THEREFORE the consecutive numbers are 19&20
Answer:
the number is 12
Step-by-step explanation:
20 - 7, 40 - 23, and 4 x 4
IT IS 6 2/3 BECAUSE 6 GOES INTO 40 6 TIMES WITH A REMAINDER OF 4. SO, IT IS 6 4/6. YOU GOT TO SIMPLY SO IT IS 6 2/3
