Elena L [17]3 years ago
5 0

Answer:

1. Yes

2. Because by moving the negative sign from the x to the 5 by dividing, the inequality sign has to switch and it'll become x>-5 as well, and vice versa,

3. x > -4

Step-by-step explanation:

For #3:

2.1x + 43.2 > 1.2 - 8.4x

2.1x + 8.4x > 1.2 - 43.2

10.5x > -42

x > -4

3. Segment GE is an angle bisector of both
777dan777 [17]

ΔHGE and ΔFGE are congruent by the Angle-Side-Angle Congruence Theorem (ASA).

<em><u>Recall:</u></em>

  • A segment that divides an angle into equal parts is known as an angle bisector.
  • Two triangles are congruent by the ASA Congruence Theorem if they share a common side and have two pairs of congruent angles.

In the diagram given, Angle bisector, GE, divides ∠HEF into congruent angles,  ∠HEG ≅ ∠GEF.

Also divides ∠FGH into congruent angles, ∠HGE ≅ ∠FGE.

Both triangles also share a common side, GE

<em>This implies that: ΔHGE and ΔFGE have:</em>

two pairs of congruent angles - ∠HEG ≅ ∠GEF and ∠HGE ≅ ∠FGE

a shared side - GE

Therefore, ΔHGE and ΔFGE are congruent by the Angle-Side-Angle Congruence Theorem (ASA).

Pls i need answer with explanation asap.
Mandarinka [93]

Answer:

4 can be rewrite as 2•2, and that's the same as 2².

8 can be rewrite as 2•2•2, and that's the same as 2³

So we can rewrite the whole expression as:

2^x = (2²)⁸•(2³)⁴

2^x = 2¹⁶•2¹²

2^x = 2²⁸

So x = 28
