The triangles ΔABE and ΔDCE are congruent to each other by the SAS postulate. Then the correct option is B.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
The triangles are ΔABE and ΔDCE.
In triangles ΔABE and ΔDCE
AE = EC (given)
∠AEB = ∠DEC (vertically opposite angles)
BE = DE (midpoint theorem)
The triangles ΔABE and ΔDCE are congruent to each other by the SAS postulate. Then the correct option is B.

(08.03)Consider the following pair of equations: y = −2x + 8 y = x − 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
[tex](3,2)[/tex]
Step-by-step explanation:
The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.
[tex]y=-2x+8\\y=x-1[/tex]
In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.
[tex]x-1 = -2x + 8[/tex]
Now solve using inverse operations,
[tex]x -1 = -2x + 8\\+2x\\\\3x - 1 = 8\\+1\\\\3x =9\\/3\\\\x = 3[/tex]
Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).
[tex]y=x - 1\\[/tex]
Substitute,
[tex]y=(3)-1[/tex]
Solve,
[tex]y=2[/tex]
Thus, the answer to this system of equations is the following, [tex](3,2)[/tex].
Answer:
(x = 3 and y = 2)
Step-by-step explanation:
Ok, we have our 2 equations...
y = -2x + 8
y = x - 1
Lets solve them
y = -2x + 8 , y = x - 1
They both equal y so I can put them together to equal out. Now our equation is...
x - 1 = -2x + 8
The next step is to get x on one side by itself, so change the negative symbol on -2 to addition...
3x - 1 = 8
Next step is to add 1 on both sides...
3x = 9
Divide both sides by 3...
x = 3
Now to do the other equation, which is easier.
y = x (3) - 1
or
y = 2
Both are solved and we have ...
(x = 3 and y = 2)
Solve 4(x-8) + 2 = -10.
Answer:
x = 5
Step-by-step explanation:
distribute 4 into (x - 8)
=> 4x - 32 + 2 = -10
combine like terms
=> 4x - 30 = -10
add 30 on both sides to isolate and solve for x
=> 4x = 20
divide both sides by 4
=> x = 5
Answer:
=5
Step-by-step explanation:
4(−8)+2=−10
4−32+2=−10
4−30=−10
4−30+30=−10+30
4=20

Answer: I beleve it is c hope this helps
Step-by-step explanation:
The transformation of the function with vertical stretching is given by the relation f ( x ) = 2 ( 1/6 )ˣ
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the parent function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = ( 1/6 )ˣ be equation (1)
And , on stretching the function by a vertical factor of 2 , we get
f ( x ) = 2 ( 1/6 )ˣ be equation (2)
Therefore , the value of f ( x ) is 2 ( 1/6 )ˣ and the graph is plotted
Hence , the transformed function is f ( x ) = 2 ( 1/6 )ˣ

arc ABC = 98° * 2 = 196°
arc CD = 360° - arc AD - arc ABC = 360°-70°-196° = 94°

A virus jumps from monkeys to humans. The number of people P(t) who have been infected with the virus t weeks after the jump grows logistically. Suppose that initially 10 people are infected with the virus and that the continuous growth rate is 1.78. It is estimated that in the long run approximately 5000 people will have been infected with the virus. The virus is spreading the fastest approximately:________
a. 3.5 weeks after the jump.
b. 4.0 weeks after the jump.
c. 4.5 weeks after the jump.
d. 5.0 weeks after the jump.
e. None of the above is correct.
Answer:
e. None of the above is correct.
Step-by-step explanation:
The general formula for exponential growth is;
P= a(1 + r)^t
Where;
P = total number infected after a given time interval
a = initial number of infected people
r = growth rate of infection
x= time taken in weeks
Hence;
5000= 10(1 + 1.78)^t
5000/10 = (1 + 1.78)^t
500 = (1 + 1.78)^t
log 500 = tlog(1 + 1.78)
t = log 500/log(1 + 1.78)
t = 2.699/0.444
t = 6 weeks
The virus is spreading the fastest approximately 5.0 weeks after the jump.
What is exponential?An exponential equation is an algebraic expression that has an equality and at least one unknown in one of its exponents. To be considered an equation, an expression must have at least one unknown, which is an unknown number represented by a letter, and an equality relationship.
The general formula for exponential growth is;
P= a(1 + r)^t
Where;
P = total number infected after a given time interval = 5000a = initial number of infected people = 10r = growth rate of infection = 1.78x= time taken in weeksHence;
[tex]5000= 10(1 + 1.78)^t\\5000/10 = (1 + 1.78)^t\\500 = (1 + 1.78)^t\\log 500 = tlog(1 + 1.78)\\t = log 500/log(1 + 1.78)\\t = 2.699/0.444\\t = 6 weeks[/tex]

The graph of quadratic function f is shown on the grid. 5 -3 -12 5 u 6 Which of these best represents the domain of f? А -5.5 < x < 1.5 B All real numbers less than or equal to 3 C All real numbers D y <3
Answer:
C: All real numbers.
Step-by-step explanation:
Domain means the interval of x=values that the function resides in. Since this quadratic function can go to both positive and negative infinity, there are no limits to the x-values so therefore the domain is all real numbers.
