Answer:
y=1/3x+6
Step-by-step explanation:
Equations parallel to each other have the same slope so that rules out the fourth answer. Perpendicular equations have opposite and reciprocal slopes, which in this case would be [tex]\frac{-1}{3}[/tex], which rules out all of the others except for the third option.

5a(y + 4) + 8(y + 4)
Answer:
Factoring the term [tex]5a(y + 4) + 8(y + 4)[/tex] we get [tex](y+4)(5a+8)[/tex]
Step-by-step explanation:
We need to factor the term: [tex]5a(y + 4) + 8(y + 4)[/tex]
Factoring:
[tex]5a(y + 4) + 8(y + 4)[/tex]
Taking (y+4) common
[tex](y+4)(5a+8)[/tex]
It cannot be further factored.
So, Factoring the term [tex]5a(y + 4) + 8(y + 4)[/tex] we get [tex](y+4)(5a+8)[/tex]

Which equation describes this line!!
Answer:
Option A: y-9=2(x-1)
Step-by-step explanation:
Notice that the answer choices are in point-slope form which is y-y1=m(x-x1)
The slope, m, is (9-3)/(1-(-2))=6/(1+2)=6/3=2, but that's given anyway.
Option A would be right because y1=9 and x1=1 which is where the line crosses through (1,9)
B is not right because that would suggest the line crosses (2,3) as y1=3 and x1=2, but it actually crosses (-2,3) so it should've been y-3=2(x+2)
C and D are wrong because the points aren't crossed through

Answer:
1. a || b ------ Given
2. m<6 = ⅛m<4 ------- Given
3. m<6 + m<4 = 180 ------- Supplementary Angles
4. m<6 + 8<m6 = 180 ---- Substitution
5. m<6 = 20; m<4 = 160 ----- Algebra
Step-by-step explanation:
Required
Fill in the gaps
1. a || b ------ Given
From the question, we understand that m<6 is ⅛ of m<4. This answers (2) as follows:
2. m<6 = ⅛m<4 ------- Given
From the attached figure, m<6 and m<4 are supplementary angles and they add up to 180. So:
3. m<6 + m<4 = 180 ------- Supplementary Angles
In (2): m<6 = ⅛m<4
Multiply both sides by 8
8 * m<6 = 8 * ⅛m<4
8m<6 = m<4
So, substitute 8m<6 for m<4 in (3). This gives (4)
4. m<6 + 8<m6 = 180 ---- Substitution
Solve (4) algebraically,
9m<6 = 180
Multiply both sides by ⅑
⅑ * 9m<6 = ⅑ * 180
m<6 = 20
Recall that m<4 = 8m<6
So:
m<4 = 8 * 20
m<4 = 160
Hence, (5) is
5. m<6 = 20; m<4 = 160 ----- Algebra

If line QN bisects angle PQR and N is the midpoint of line PR classify each triangle by its angles and sides
Answer:
The answer is "Equiangular, Equilateral"
Step-by-step explanation:
please find the complete question in the file.
In this question, the answer is equiangular, in which the triangle was considered an equilateral triangle with 3 parallel inner angles. It's the measurement of each of these interior angles is 60 degrees, inside an equiangular triangle, and although there 3 parallel sides of an equiangular triangle, so it is just like an equilateral triangle.
Based on the sides and angles of a triangle, triangle PQR would be classified as: an equilateral triangle.
Recall:
An equilateral triangle all three sides that are congruent and also has all of its three interior angles equal to 60 degrees each.In the diagram given (see image attached below), we have the following:
PQ = RQ = 14 (congruent sides)
PN = NR = 7 (N is the midpoint of PR)
Therefore:
PR = PN + NR
SubstitutePR = 7 + 7 = 14
This shows that triangle PQR has equal side lengths measuring 14 units (PQ = RQ = PR = 14).
Also, we are given that:m<QPR = m<QRP = 60 degrees (two congruent angles).
Taking right triangle QNR into consideration,m<NQR = 180 - (90 + 60) (sum of triangle)
m<NQR = 30 degrees
Therefore:
m<PQR = m<NQR + m<PQN
Substitutem<PQR = 30 + 30
m<PQR = 60 degrees.
This means that, triangle PQR has three equal angles measuring 60 degrees each (<PQR = <QPR = <QRP = 60 degrees).
Therefore, based on the sides and angles of a triangle, triangle PQR would be classified as: an equilateral triangle.
