Answer:
<h3>Q 1</h3>
U and S are congruent and sum of 4 angles is 360.
- 130 + 2*80 + m∠T = 360
- m∠T = 360 - 290
- m∠T = 70
Correct choice is B
<h3>Q 2</h3>
∠1 and ∠3 are complementary, AC is angle bisector and ∠2 is right angle since diagonals of a kite are perpendicular
- ∠DAC≅∠BAC
- m∠1 = 39°
- m∠3 = 90° - 39° = 51°
Correct choice is C
<h3>Q 14</h3>
- A- guaranteed
- B- guaranteed
- C- guaranteed
- D- not guaranteed as it could be a rhombus
The solution(s) of a system of linear equations give points of intersection of specific lines or planes.
The solution(s) of a system of linear inequalities give areas of intersection wherein any specific pair of points or lines are solutions.
PROCESS-WISE there are little differences between solving systems. However, multiplication and division by negatives reverses the signs in inequalities.
Answer:
±5
Step-by-step explanation:
The double bar around <em>n</em> is absolute value. This means that any number plugged in will turn positive.
Therefore, there are only 2 numbers that can be inputted: -5 and 5.
|-5| = 5
|5| = 5
