Answer:
Option A is correct.
The missing justification is: Transitive property
Step-by-step explanation:
Given: 
, 
Symmetric property of equality states the if for all real values of x , y
if x =y then, y =x.
Then, by symmetric property of equality:
we can write as
Transitive property of equality states that if we have the two things that are equal to each other and the second thing is equal to a third thing.
i.e, if a =b and b =c
then a =c
By transitive property of equality:
if and
then;
......[1]
Congruent angle states that the angles have exact the same measure
Therefore, by definition of congruent angles in [1] we have;
Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.
Hope this helps!
Answer: D
Step-by-step explanation: y=2 so 2+2=4+1=5
To determine the effect of the radius changes to the coefficients, we need to rewrite the form of the equation into:
(x−α)²+(y−β)²=r²
From the equation, we will see that:
C=−α∗2
D=−β∗2
and α²+β²−r²=E
where r represents the radius of the circle and α,βare the coordinate of the center of the circle.
Therefore, when the r decreases the coefficients C and D do not change but E increases.
