Answer:
135
Step-by-step explanation:
Then add the first and last number i.e.
433+107===> 540
divide 540 by 4
540/4
= 135
134
-107/4 = -26.75
429/4 = 107.25
107.25 - (-26.75)
107.25 + 26.75 = 134
2nd quadrant.
(10 - 8)/(-21 + 9)= 12/-12= -1
y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
-52
You can clear fractions by multiplying by 3:
3(1/3x) -3(2/3) = 3(-18)
x -2 = -54
add 2:
x = -52
