Answer:
Step-by-step explanation:
What is the VALUE OF 3r=10+5 when r=10?
substitute 10 for r in 3r=10+5. We get:
3(10) = 10 + 5, or 30 = 15. This equation is FALSE when r = 10.
You could solve the equation for r, however:
3r=10+5 becomes 3r = 15, and so r = 5. 5 is a solution; 10 is not a solution.

Find the zeros of function:



We have two zeros

Thus zeros of function are 
Answer:
The correct options are;
1. Definition of supplementary angles
2. m∠1 + m∠2 = m∠1 + m∠3
3. m∠2 = m∠3
4. Definition of congruent angles
Step-by-step explanation:
The two column proof is presented as follows;
Statement
Reason
1. ∠1 and ∠2 are supplementary
Given
∠1 and ∠3 are supplementary
2. m∠1 + m∠2 = 180°
(1) Definition of supplementary angles
m∠1 + m∠3 = 180°
3. (2) m∠1 + m∠2 = m∠1 + m∠3
Transitive Property
4. (3) m∠2 = m∠3
Subtraction property of equality
5. ∠2 ≅ ∠3
(4) Definition of congruent angles
Given that angles ∠1 and ∠2 are supplementary, we have, ∠1 + ∠2 = 180°
Given that angles ∠1 and ∠3 are also supplementary, we also have, ∠1 + ∠3 = 180°
∴ ∠1 + ∠2 = 180° = ∠1 + ∠3
∠1 + ∠2 = ∠1 + ∠3
∠1 + ∠2 - ∠1 = ∠1 + ∠3 - ∠1
∴ ∠2 = ∠3
∴ ∠2 ≅ ∠3, by definition of congruent angles.
You would have to convert subtraction to addition. so it would be -5/18 + 1/4.
-5/18+1/4 is -0.028 rounded up
