how to construct an angle bisector of a given angle.
how to use an angle bisector to construct some angles for example, 90 degrees, 45 degrees, 60 degrees, 30 degrees, 120 degrees, 135 degrees, 15 degrees.
An angle bisector is a straight line that divides the angle into two equal parts.
Example: Construct an angle bisector for the following angle:
Solution:
Step 1 : Put the sharp end of your compasses at point B and make one arc on the line BC (point S) and another arc on line AB (point T).
Step 2 : Put the sharp end of the compasses at S and make an arc within the lines AB and BC. Do the same at T and make sure that the second arc intersects the first arc.
construct angle bisector
Step 3 : Draw a line from point B to the points of intersection of the 2 arcs. This line bisects ∠ABC.
construct angle bisector
The steps to construct an angle bisector can be summarized as follows:
1. From the vertex, draw an arc across both rays of the angle.
2. From each arc intersection draw another pair of arcs that intersect each other.
3. Draw a line from the vertex to the intersection point to form the angle bisector.

Five students each wrote an expression to represent the perimeter of the given rectangle. Terrell wrote this correct expression: (2x + 2x) + (5x + 5x) + (1 + 1). Circle the name of the student who wrote an incorrect expression. Explain why the expression is incorrect. Anya: 2x + 2x + 5x + 1 + 5x + 1 Katrin: 2(5x + 1) + 2x Luis 2(2x) + 2(5x + 1) Steve: 1 + 1 + x(2 + 2 + 5 + 5)
Answer:
Luis wrote an incorrect expression.
Step-by-step explanation:
As per Terrell, the correct expression is (2x+2x) + (5x+5x) + (1+1) which is equal to 12x + 2
For you who got incorrect answer, the answer if you simplified it must be 12x + 2. Let's check:
Anya 2x+2x+5x+1+5x+1 =
12x + 2 [CORRECT]
Katrin 2(5x+1) + 2x
10x+2+2x
12x + 2 [CORRECT]
Luis 2(2x) + 2(5x+1)
4x+10x+2
14x + 2 [INCORRECT]
Steve 1+1+ x(2+2+5+5)
2+ x(12)
12x + 2 [CORRECT]

Does the table represent an exponential function? Explain.
A. Yes, the x-values decrease by a constant amount and the y-values are multiplied by a constant amount.
B. No, the x- and y-values show a quadratic relationship only.
C. Yes, the x-values increase by a constant amount and the y-values are multiplied by a constant amount.
D. Yes, the y-values increase by a constant amount and the x-values are multiplied by a constant amount.
Answer:
No, because as the x-values are increasing by a constant amount, the y-values are not being multiplied by a constant amount.
Step-by-step explanation:
We have a set of ordered pairs of the form (x, y)
If a function is exponential then the ratio between the consecutive values of y, is always equal to a constant.
This means that:
\frac{y_2}{y_1}=\frac{y_3}{y_2}=\frac{y_4}{y_3}=by1y2=y2y3=y3y4=b
This is: y_2=by_1y2=by1
Now we have this set of points {(-1, -5), (0, -3), (1, -1), (2, 1)}
Observe that:
\begin{gathered}\frac{y_2}{y_1}=\frac{-3}{-5}=\frac{3}{5}\\\\\frac{y_3}{y_2}=\frac{-1}{-3}=\frac{1}{3}\\\\\frac{3}{5}\neq \frac{1}{3}\end{gathered}y1y2=−5−3=53y2y3=−3−1=3153=31
Then the values of y are not multiplied by a constant amount "b"

Answer:
(2, -1)Step-by-step explanation:
Given system:
-3x - 2y = -49x + 3y = 15Solving by elimination
Multiply the first equation by 3 and add up equations, then solve for y:
3(-3x) - 3(2y) + 9x + 3y = 3(-4) + 15-9x - 6y + 9x + 3y = -12 + 15-3y = 3y = 3/(-3)y = -1Find the value of x:
-3x - 2(-1) = -4-3x + 2 = -4-3x = - 4 - 2-3x = -6x = -6/(-3)x = 2The answer is: (2, -1)

Answer: 1/14, 2/28.
Step-by-step explanation:
2/7 x 0.25 =
Convert 0.25 into a fraction.
0.25 = 1/4.
Multiply the numerators together and then multiply the denominators with each other.
1/4 x 2/7 = 2/28.
Therefore, the answer is 2/28, but it can also be simplified to 1/14. So the answer is the first one, or 1/14.
Answer:
1/14 or A
Step-by-step explanation:
0.25 as a fraction is 1/4
1/4 x 2/7 = 2/28, simplify to become 1/14, and there is your answer

La suma de las edades de los hermanos Carlos y Felipe es igual a la edad de su tía María; Si María tiene 29 años y Carlos tiene 13 años, ¿Cuántos años tiene Felipe?
Answer:
16 años
Step-by-step explanation:
Si la suma de la edad de Carlos y Felipe es igual a la de Maria, y en la pregunta nos dan la edad de Maria (M) y Carlos (C), entonces tenemos que encontrar la edad de Felipe. Para calcular esto necesitamos restar la edad de Carlos de la edad de Maria. Esto nos dara la edad exacta de Felipe (f).
M - C = f
29 - 13 = f
16 = f
Finalmente, vemos que la edad de Felipe es de 16 años

Which conclusion does the diagram support?
Answer:
The conclusion supported by the diagram is;
(A) [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]
Step-by-step explanation:
The question is examines the theorem that two transversals cut by three or more parallel lines are proportionally divided by the transversals
The given parallel lines are;
Line CD, line BE, and line line AB
The given transversals are;
Line AC and line DF
Therefore, by the above three or more parallel lines cutting two transversal theorem, we have;
BC/AB = ED/FE, BC/DF = AB/FE, CA/AB = DF/FE
From BC/AB = ED/FE, we find the inverse of both sides to get;
[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{1}{\dfrac{ED}{FE} }[/tex]
[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{AB}{BC} \ and \ \dfrac{1}{\dfrac{ED}{FE} } = \dfrac{FE}{ED}[/tex]
[tex]\therefore \ \dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]
The correct option is [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]
