Answer:
El chico nació en el año 18 antes de cristo.
La madre nació en el año 40.
Step-by-step explanation:
Las respuestas son fáciles:
- Si en el año 5, el hijo tiene 13 años, hagamos que a partir del año 0 después de cristo sea positivo.
-13-(-5) = -18
- Madre:
-18-22 = -40
Entonces, su edad debería ser negativa, simplemente cambiamos el símbolo y lo pasamos a positivo.
Answer:
2y-4x
Step-by-step explanation:
Answer:
y = 2x+5
Step-by-step explanation:
rearrange the equation to make y the sof
y = 1/2x - 3
to find gradient of perpendicular line
1/2 ÷ ( - 1 )
y = -2x + c , the replace the coordinates (-3,-1)
y = 2x + 5
Answer:
The angles 
are used to prove the similarity of triangles VWZ and YXZ.
Step-by-step explanation:
Given information: 
Two triangles are called congruent if their corresponding sides are in same proportion or the corresponding angles are same.
If two corresponding sides of triangle have same proportion and their inclined angle is same, then by SAS rule of similarity both triangles are similar.
From the given figure it is noticed that the ∠VZW and ∠YZX are vertically opposite angles. The vertically opposite angles are always equal.
(Vertically opposite angles)
(Given)
By SAS rule of similarity
Therefore the angles are used to prove the similarity of triangles VWZ and YXZ.
Your answer would be 7y^(3)+32y^(2)+9
