The key to proving that two triangles are similar or congruent is to prove that three of either side lengths or angles are congrunet, similar or the same.
For the figure given, we have already been told that
Side AB = Side CD
Side AD = Side CB
Since the two triangles share a similar side in BD, we can complete this by saying
Side BD = Side BD
Side AB = Side CD
Side AD = Side CB
Side BD = Side BD
So, three of the sides of the triangles are equal or congruent.

What are linear equation?X 1, ldots, and x n are the variables, and display style b, a 1, ldots, and a n are the coefficients. In mathematics, a linear equation is an equation that can be written as x 1, ldots, and x n + a n + b = 0. Ax + By = C is the typical form for linear equations involving two variables. A linear equation in standard form is, for instance, 2x+3y=5. Finding both intercepts of an equation in this format is rather simple (x and y). frequently actual numbers. The first-degree equations are linear equations. The following is the equation for a straight line. Ax+by+c = 0, where a and b are both zeros, is the conventional form of a linear equation.

Solve by substitution
Answer:
consistent system with equation [tex]y=6x+5[/tex]
Step-by-step explanation:
[tex]18x-3y=-15[/tex], [tex]-6x+y=5[/tex]
To solve by substitution, we have to isolate a variable in one of the equations. I will isolate y in the second equation.
[tex]-6x+y=5[/tex]
+6x +6x
[tex]y=6x+5[/tex]
Next, substitute this y value for y in the first equation:
[tex]18x-3y=-15[/tex]
[tex]18x-3(6x+5)=-15[/tex]
and distribute.
[tex]18x-18x-15=-15[/tex]

Blood types: The blood type O negative is called the "universal donor" type, because it is the only blood type that may safely be transfused into any person.
Therefore, when someone needs a transfusion in an emergency and their blood type cannot be determined, they are given type O negative blood. For this
reason, donors with this blood type are crucial to blood banks. Unfortunately, this blood type is fairly rare; according to the Red Cross, only 7% of U.S. residents
have type O negative blood. Assume that a blood bank has recruited 19 donors. Round the answers to four decimal places.
a) what is the probability that three or more of them have type O negative blood?
b) what is the probability that fewer than four of them have type O negative blood?
c) It (would/wouldn’t) be unusual if none of the donors had type O negative blood since the probability is __?
a) It is 0.1275 times more probability that fewer than five of them have type o negative blood.
b) The probability that less than five of them are type o negative blood types is 0.9933.
c) 0.2708 probability that there are no donors who have type O negative blood. It would not be odd to have no type o negative donors because this likelihood is higher than 0.05.
There are only two outcomes that can occur for any individual. Type o negative blood is either present or absent. Any other person has no effect on a person's likelihood of having type O negative blood. To answer this question, we thus employ the binomial probability distribution.
Binomial probability distributionThe probability of precisely x successes on n repeated trials is known as a binomial probability, and X can only have two possible outcomes.
P(X=x)= [tex]C_{n,x.P^{x}.(1-P)^{n-x} }[/tex]
Additionally, p is the probability that X will occur.
A whopping 7% of Americans have type o negative blood.This means that P=0.07
18 donors.This mean that n = 18
the probability that three or more of them have type o negative bloodEither less than three have, or at least three do. The sum of the probabilities of these events is 1. So
P(X<3) + P(X≥3)=1
We want P(X≥3)
So,
P(X≥3) = 1-P(X<3)
In which
P(X< 3)= P(X = 0)+P(X = 1)+P(X = 2) = 0.2708 + 0.3669 +0.2348 = 0.8725
P(X≥3) = 1-P(X<3) = 1- 0.8725=0.1275
It's 0.1275 times more likely that fewer than five of them have type O negative blood.
The probability that fewer than five of them have type o negative bloodP ( x < 5 )= P(X=0)+P(X=1)+P(X=3)+P(X=3)+P(X=4)
P(X=x)= [tex]C_{n,x.P^{x}.(1-P)^{n-x} }[/tex]
P(X=0)= [tex]C_{18,0(0.07)^{0}.(0.93)^{18} }= 0.2708[/tex]
P(X=1)= [tex]C_{18,1(0.07)^{1}.(0.93)^{17} }= 0.3669[/tex]
P(X=2)= [tex]C_{18,2(0.07)^{2}.(0.93)^{16} }= 0.2348[/tex]
P(X=3)= [tex]C_{18,3(0.07)^{3}.(0.93)^{15} }= 0.0942[/tex]
P(X=4))= [tex]C_{18,4(0.07)^{4}.(0.93)^{14} }= 0.0266[/tex]
P(X < 5)=P(X=0)+P(X=1)+P(X=3)+P(X=3)+P(X=4)
0.2708+0.3669+0.2348+0.0942+0.0266=0.9933
Would it be unusual f none of the donors had type o negative bloodP(X=0)= [tex]C_{18,0(0.07)^{0}.(0.93)^{18} }= 0.2708[/tex]
Probability of having no type O negative blood donors is 0.2708. It would not be odd to have no type o negative donors because this likelihood is higher than 0.05.

Step-by-step explanation:
the range is the interval or set of all valid y (functional result) values.
we see that y goes continuously through every value between +5 (we see no y values bigger than that) and -5 (we see no y values lower than that).
the filled dots also tell us that the end points would be included (if this would be a necessary information - it is not, because the curve reaches +5 and -5 also in between).
so, the range is
-5 <= y <= +5

The correct options are,
A. Rectangle ABCD is similar to rectangle EFGH.
D. The dilation is an enlargement.
F. The scale factor of the dilation is 2.5.
The similarity criteria of rectangles are that their corresponding sides should be proportional to each other. The ratio of their corresponding length is equal to L = 25÷10, which gives L=2.5, and the ratio of their corresponding width is equal to W = 15÷6, which gives w = 2.5. Hence, both rectangles are similar.
The dilation is an enlargement because the size of the rectangle is increased by a scale factor of 2.5.
The scale factor of the dilation is the ratio of the sides, which is equal to 2.5.

odd even or neitheer
how many mistakes i have explain it to me
Answer:
neitheroddoddevenevenneitherevenevenStep-by-step explanation:
You want to classify a number of functions as even, odd, or neither.
Even FunctionAn even function has a graph that is symmetrical about the y-axis. It has the characteristic that ...
f(x) = f(-x)
A polynomial function will be an even function if it consists entirely of even-degree terms. (A constant is degree zero, hence even degree.) A rational function will be an even function if it can be reduced to the ratio of even functions.
Odd FunctionAn odd function has a graph that is symmetrical about the origin. It has the characteristic that ...
f(x) = -f(-x)
A polynomial function will be an odd function if it consists entirely of odd-degree terms. A rational function will be an odd function if it reduces to the ratio of an even and an odd function.
NeitherA function is neither even nor odd if it does not have one of the symmetries mentioned above. A polynomial consisting of a mix of even- and odd-degree terms will be neither even nor odd.
1. (x³+4x²)/(7x²+1)This is the ratio of a "neither" function to an even function. It is neither even nor odd.
2. (2x⁴+8x³)/(x³+4x²)The ratio can be reduced to ...
[tex]\dfrac{2x^4+8x^3}{x^3+4x^2}=\dfrac{2x^3(x+4)}{x^2(x+4)}=2x[/tex]
This consists only of an odd-degree term. It is an odd function.
3. x³/(7x²+1)This is the ratio of an odd function to an even function. It is an odd function.
4. (4x²+7)/(7x⁸+3x²)This is the ratio of two even functions. It is an even function.
5. (2x³+8x²)/(x³+4x²)As in problem 2, the function can be reduced:
[tex]\dfrac{2x^3+8x^2}{x^3+4x^2}=\dfrac{2(x^3+4x^2)}{x^3+4x^2}=2[/tex]
It is an even (degree 0) function.
6. (x²-4)/(x-2)This is the ratio of an even function to a "neither" function. It is neither even nor odd.
The function reduces to x+2, which is neither even nor odd.
7. 1/(x²+9x⁶)This is the ratio of two even functions. It is an even function.
8. (4x³+2x)/(7x⁵+3x³)This is the ratio of two odd functions. It can be reduced to the ratio of two even functions, so it is an even function.
[tex]\dfrac{4x^3+2x}{7x^5+3x^3}=\dfrac{2x(2x^2+1)}{x^3(7x^2+3)}=\dfrac{4x^2+2}{7x^4+3x^2}[/tex]

[tex]\lim _{x->2^-}(\frac{x}{x-2})=-\infty[/tex][tex]\begin{gathered} \lim _{x->2^+}(6)=6 \\ \end{gathered}[/tex]Since:
[tex]\lim _{x->2^+}f(x)\ne\lim _{x->2^-}f(x)[/tex]The function is discontinuous at x = 2. Besides since the function has a vertical asymptote on one of the sides, we can conclude it is a infinite discontinuity.
For x = 6:
[tex]\lim _{x->6^-}6=6[/tex][tex]\lim _{x->6^+}\frac{x-2}{x^2-6x+8}=\lim _{x->6^+}\frac{x-2}{(x-2)(x-4)}=\lim _{x->6^+}\frac{1}{x-4}=\frac{1}{2}[/tex]Since:
[tex]\lim _{x->6^+}f(x)\ne\lim _{x->6^-}f(x)[/tex]The function is discontinuous at x = 6, at this point the function has a jump discontinuity
Given: f (x) = 2x² − 3x+5 and g(x)=x-4, find (f+g)(x) * help
The value of (f+g)(x) is c(x) = 2x² + (-2)x + 1.
How can we add linear functions?
Addition of two individual functions, a(x) and b(x); linearly, results in the formation of the functional addition, c(x) of the two functions, such as
c(x) = a(x) + b(x) = (a+b)(x) – (i)
Domain of a quadratic equation:
The domain of a quadratic function f(x) is the set of x-values for which the function is defined, and the range is the set of all the output values, as is the case with any function (values of f). Any x is a valid input for quadratic functions because their domain is typically the entire real line. Generally, for a quadratic equation the domain goes from (-∞ ,∞ ).
Given, f(x)= 2x² - 3x + 5 and g(x)= x - 4
Let, y = c(x) denote the value of the function (f+g)(x).
Here, following available literature,
c(x) = (f+g)(x) = f(x) + g(x) [Using (i)]
c(x) = (2x² - 3x + 5)+(x - 4) = 2x² - 3x + 5 + x - 4 = 2x² + (-2)x + 1
Therefore, y = c(x) = 2x² + (-2)x + 1 is the value of (f+g)(x).

The slope of the equation, represented by the value of y/x for the given values of x and y, is 3/1, 3/1, 3.
What does slope in mathematics mean?The slope of a line can be used to gauge how steep it is. Slope is theoretically determined as "rise over run" (change in y divided by change in x).
The slope is the ratio of the rise in height between two points to the fall in elevation between those same two points.
The x and y values are provided.
The equation's slope is shown by the ratio y/x.
if y = -3 and x = -1,
y/x = 3/1
