Answer:
-1 .6
Step-by-step explanation:
-7 minus 1 equals -8 and 9 minus 4 equals 5 so -8 divided by 5 equals -1.6 and that is your answer
8/5
use the formula (y2-y1)/(x2-x1)
(1+7)/(9-4)
7
line in the middle is an angle bisector
14/6 = 21 / 3x - 12
first, cross multiply
14 (3x - 12) = 6*21
Remove the brackets
42x - 168 = 126
Add 168 to both sides
42x = 168 + 126
Combine
42x = 294
Divide by 42
x = 294/42
x = 7
