Answer:
-31
Step-by-step explanation:
-34 - -17 is actually -34 + 17, so you get -17. -17 - 14 = -31
1 - 2x < 11
-2x < 10
x < -5
Jack's mistake is that he was supposed to divide by -2 on both sides of the inequality, but he did not do that. By dividing by -2, he will get x < -5.
Answer:
Ray : Line NA, Line NB, Line AB
Vertex : Vertex N
Angle: Angle ANB
Parallel Lines: None
Coplanar Points: Points C, A, F, N, B
Collinear Points: Points A, N, B
Segment Addition Postulate: AN + NB = AB
Perpendicular Lines: None
Answer:
-25 and 2
Step-by-step explanation:
x + y = -23
xy = 50, so y = 50 /x
.
x + 50/x =-23, x^2 +23x - 50 = (x-2)(x+25)
so 2 and -25
Answer:
x = -9
Step-by-step explanation:
ANGLES IN A TRIANGLE ADD UP TO 180°
50° + 80° = 130°
180° - 130° = 50
x+59 = 50
x = -9
