Equality Properties
Step-by-step explanation:
<u>Step 1: Define</u>
3n - 5 = 22
<u>Step 2: Solve for </u><em><u>n</u></em>
- Add 5 to both sides: 3n = 27
- Divide 3 on both sides: n = 9
Answer:
This proof involves the definitions of congruence and supplementary angles, as well as some of the properties of equality.
∠1 and ∠2 are supplementary // given
∠3 and ∠4 are supplementary // given
∠1 ≅ ∠3 // given
m∠1 + m∠2 = 180° // definition of supplementary angles
m∠3 + m∠4 = 180° // definition of supplementary angles
m∠1 + m∠2 = m∠3 + m∠4 // transitive property of equality
m∠1 = m∠3 // definition of congruent angles
m∠1 + m∠2 = m∠1 + m∠4 // substitution property of equality (replaced m∠3 with m∠1)
m∠2 = m∠4 // subtraction property of equality (subtracted m∠1 from both sides)
∠2 ≅ ∠4 // definition of congruent angles

Answer:
(4,-7) is the vertex
Step-by-step explanation:
The equation of the parabola is of the form
y= a(x-h)^2 +k
where (h,k) is the vertex
f(x) = -2(x – 4)^2 – 7
(4,-7) is the vertex
