Answers
Answer:
A) true
B) false
c) true
d) true
Step-by-step explanation:
A) angles 7 and 6 are vertical angles, which means they're equal.
so, A is True.
B) angles 7 and 5 are supplementary angles, which means they add up to 180. 135 + 55 is 190. so B is False
C) angle 7 is equal to angle 3, which is supplementary to angle 1.
so, 55 + angle 1 = 180
55 + angle1 = 180
subtract 55 from both sides of the equation
angle1 = 180 - 55
angle 1 = 125.
angles a and 4 are vertical angles, so they are equal. if you add them together that would be 125 + 125
125 + 125 = 250
so, C is True
D) angles 1 and 6 are supplementary, and angles 2 and 7. since they both add together to make 180, D is True

Answer:
x = -1/2 or -0.5
Step-by-step explanation:
4(2x - 2) + 2 = 4(x - 2)
open the parenthesis
8x - 8 + 2 = 4x - 8
add 8 to both sides of the equation
8x - 8 + 2 + 8 = 4x - 8 + 8
combine like terms
8x + 2 = 4x
subtract 4x from both sides of the equation
8x - 4x + 2 = 0
4x + 2 = 0
subtract 2 from both sides of the equation
4x + 2 - 2 = 0 -2
4x = -2
divide both sides by 4
4x/4 = -2/4
x = -1/2

What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The value of x is,
⇒ x = - 1
Now, Substitute the value of x in all equations and check the correct equation.
For equation 3;
⇒ - 3x + 15 = 18
Substitute x = - 1 ;
⇒ -3×-1 + 15 = 18
⇒ 3 + 15 = 18
⇒ 18 = 18
Thus, The correct equation is,
⇒ - 3x + 15 = 18

What are the missing parts that correctly complete the proof? Given: Point A is on the perpendicular bisector of segment P Q. Prove: Point A is equidistant from the endpoints of segment P Q. Image: A horizontal line segment P Q. A midpoint is drawn on segment P Q labeled as X. A vertical line X A is drawn. A is above the horizontal line. The angle A X Q is labeled a right angle. The line segments P X and Q X are labeled with a single tick mark. A dotted line is used to connect point P with point A. Another dotted line is used to connect point Q with point A.

Answers
Answer:
These are the answers in order
Step-by-step explanation:
1. Definition of bisector
2. Definition of perpendicular
3. ∠AXP ≅ ∠AXQ
4. SAS Congruence Postulate
5. Corresponding parts of congruent triangles are congruent
The missing parts that complete the proof are;
2) Definition of a bisector.
3) Perpendicular Definition.
4) ∠AXP ≅ ∠AXQ
6) SAS Congruence Theorem.
7) Corresponding sides of 2 congruent triangles are congruent.
We are given that;Point A is the perpendicular bisector of PQ
Point A is equidistant from the endpoints of PQ.
2) We are told that PX = QX; Since A bisects PQ at X, it means it divides it into 2 equal parts. Thus, this id true because it corresponds with the definition of a bisector.3. ∠AXP and ∠AXQ are right angles; Since perpendicular means right angle or 90°, we can say that this statement is true because it corresponds with the definition of perpendicular.
4. All right angles are congruent; This simply means they are equal. Thus, the two right angles here ∠AXP and ∠AXQ are congruent. We can write this with congruency symbol as; ∠AXP ≅ ∠AXQ
6. △AXP≅△AXQ; This means that △AXP is congruent to △AXQ. From the diagram, we can see that AP = AQ and that QX = PX and that ∠AXP = ∠AXQ. This means 2 corresponding sides and one corresponding angle are equal and the congruence theorem this depicts is SAS Congruence Theorem.
7. AP = AQ; This is true because we are told A is equidistant from both P and Q. Also, from the SAS congruency theorem, we can say that the corresponding sides AP and AQ are congruent.
