First Degree Equations
A first-degree equation can have one, none, or infinitely many solutions.
An equation like
2x + 3 = -x + 6
Has one solution: x=1
An equation like:
4x + 2 = 4x + 1
Has no solutions because when trying to solve for x we get:
2 = 1
This equality is false and no value of x can make it true
Finally, the equation:
3x + 2 = x + 2x + 2
Has infiniteyl many solutions, because when trying to solve it, we get:
2 = 2
Which is true regardless of the value of x
The first given equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:
8x + 9 = 8x -3, or
8x + 9 = 8x + 4
The second given equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:
8x + 9 = 3x + 9
8x + 9 = -x + 5
8x + 9 = 0
The third equation:3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:
8x + 9 = 8x + 9

he steps below describe the construction of a line AG that is parallel to segment PQ and passes through a point A outside of PQ: Step 1 shows a segment PQ with an external point A. A line drawn from A intersects PQ at a point B. Step 2 shows an arc drawn from B that intersects BQ in D and BA in E. Step 3 shows an arc drawn from Point A that intersects the segment BA extended in a point F. Which statement describes the next step?
Answers
Answer: Point G is obtained by using the same compass width and drawing an arc from point F, intersecting the arc drawn from A
Step-by-step explanation:
I took the test and got the right answer
The steps for constructing a parallel line require steps for constructing
angles of equal measures.
The statement that describes the next step is; The width of the compass is adjusted to DE and an arc is drawn from point F.Reasons:
The steps to construct the AG parallel to PQ, passing through the point A
outside of PQ are as follows;
Step 1; A line is drawn from point A to intersect PQ at point B.
Step 2; From point B on PQ, an arc is drawn intersecting segment BQ of PQ at D and segment BA at point E.
Step 3; To construct the angle equal to angle ∠DBE at point A, an arc is drawn from Point A with radius BD, that intersects the segment BA extended in point F
Therefore;
To construct an angle equal to the angle ∠DBE to point A, we have;
The width of the compass is adjusted to DE, and an arc is drawn from point F to intersect the arc drawn from point A with radius BD at point G.The points A and G can then be joined with a straight line and extended to form the line AG.
The correct option is therefore;
The width of the compass is adjusted to DE and an arc is drawn from point FLearn more about constructing a parallel line here:

Answers
Answer:
5. En el año 2007, la producción comercial de celdas solares llegaba a 89.6 %. Razón: Esa producción comercial se reportó hace 13 años. (Celdas solares -> 2007)
4. Leonardo da Vinci diseñó un avión en el siglo XV. Razón: El siglo XV corresponde al período de la historia humana entre los años 1401 y 1500, lo cual da una distancia de tiempo entre 520 y 619 años. (Avión -> Siglo XV)
3. La primera evidencia de un reloj de arena se halló en el año 1328. Razón: La distancia de tiempo es de 692 años. (Reloj de arena -> 1328)
1. Un zapoteca sembró el árbol de Tule hace veinte siglos. Razón: Un siglo equivale a 100 años, entonces veinte siglos son 2000 años. En consecuencia, la distancia de tiempo es de 2000 años. (Árbol de Tule -> Hacia el año 20)
2. Hace 3500 años, los egipcios inventaron el reloj solar. Razón: La distancia de tiempo es de 3500 años. (Reloj solar -> 1500 a.C.)
6. Hace cien crones había dinosaurios. Razón: Un crón equivale a un millón de años, entonces cien crones equivalen a cien millones de años. (Dinosaurios -> Hace 100 millones de años)
Step-by-step explanation:
Antes de proceder a la resolución de este problema, procedemos a ilustrar las cantidades de tiempo reportadas:
a) Un siglo es un período de tiempo equivalente a 100 años.
b) Todos las cantidades se calculan con respecto al año de publicación de esta respuesta, es decir, en 2020.
c) Un crón equivale a un millón de años.

2x = 86
x = 86/2
