Assuming we're dealing with
, which is the same as writing (x+2)/(-5) < 4, then the answer is choice C.
We multiply both sides by -5 and this will flip the inequality sign.
-------------------------------------
Multiplying or dividing both sides by a negative number flips the inequality sign.
An example would be saying -2x < 10 leads to x > -5
What we can do is divide both sides by -2 and flip the inequality sign, or we could follow the steps shown below
- -2x < 10
- 0 < 10+2x ... adding 2x to both sides
- -10 < 2x ... subtracting 10 from both sides; this is one way to see why the sign flip happens
- 2x > -10
- x > -10/2 ..... dividing both sides by 2
- x > -5

Answer:
r = 63 meters
Step-by-step explanation:
C=2πr
We know pi and C
396 = 2*22/7*r
396 = 44/7 *r
Multiply each side by 7/44 to isolate r
396*7/44 = 7/44 *44/7 *r
63 =r
Answer:
He is bisecting the angle BAC.
Step-by-step explanation:
First he puts the compass point at point A and draws 2 small arcs at D and E. Then he places the compass point at D and then at E to form the 2 arcs that cross between the 2 line segments AB and AC.
The bisector is the line he can draw between A and the crossed arcs.
