Answer:
7x3 is 21 so 22 Is the answer
The midpoint of a segment is (6,−4) and one endpoint is (13,−2). Find the coordinates of the other endpoint.
A. (20, -6)
B. (-1, 0)
C. (-1, -6)
D. (20, 0)
Answer:
(-1,-6)
Step-by-step explanation:
(13 + x)/2 = 6
13+x= 12
x = -1
~~~~~~~~~~~~~~~
(-2 + y ) / 2 = -4
-2 + y = -8
y = -6
The coordinates of the other endpoint will be (-1,-6). The correct option is C.
What is the midpoint of the line?Divide the measurement of the distance between the two end locations by 2. The middle of that line is located at this separation from either end.
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Given that the midpoint of a segment is (6,−4) and one endpoint is (13,−2).
The x- coordinate will be calculated as:-
(13 + x)/2 = 6
13+x= 12
x = -1
The y-coordinate will be calculated as:-
(-2 + y ) / 2 = -4
-2 + y = -8
y = -6
Therefore, the coordinates of the other endpoint will be (-1,-6). The correct option is C.

Answer: 10
Step-by-step explanation:
So since this is all about perimeter you just got to add the values together. So lets use 12 as the denominator for every fraction. 1/4 is equal to 3/12 and 2/3 is equal to 8/12. So in conclusion 3/12 plus 8/12 and 1/12 will equal 1 in total. and then add up all the whole numbers 4 + 2 + 3 + 1 will get you 10. So 10 is your answer.

Let $x$ be the smallest number in the following list, and let $y$ be the second smallest number (that is, the smallest number other than $x$). \[ 5, \qquad -22, \qquad \frac{-4}{7}, \qquad \frac{-3}{-5}, \qquad 3, \qquad \frac{-8}{13} \]Find $\frac{x-y}{y}$. Express your answer as a fraction in simplest form.
Answer:
139/4
Step-by-step explanation:
and find that\[
\frac{4}{7}\cdot \frac{13}{13} = \frac{4\cdot 13}{91}=\frac{52}{91}, \text{and}
\]\[
\frac{8}{13}\cdot \frac{7}{7} = \frac{8\cdot 7}{91} = \frac{56}{91}.
\]Thus $\frac{8}{13}$ is larger than $\frac{4}{7}$, which tells us that $-\frac{8}{13}$ is smaller than $-\frac{4}{7}$. Thus, $x=-22$, $y=-\frac{8}{13}$, and\begin{align*}
\frac{x-y}{y}&=\frac{-22-\left(-\frac{8}{13}\right)}{-\frac{8}{13}}\\
&=\left(-22\cdot \frac{13}{13}+\left(\frac{8}{13}\right)\right)\cdot \left(-\frac{13}{8}\right)\\
&=\left(\frac{-286+8}{13}\right)\cdot \left(-\frac{13}{8}\right)\\
&=\left(-\frac{278}{13}\right)\cdot \left(-\frac{13}{8}\right)\\
&=\boxed{\frac{139}{4}}.

n<-2 or n≥4 compound inequality is represented in the third graph.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given inequality is n<-2 or n≥4
The third number line represents the inequality n<-2 or n≥4.
The open circle at -2 indicates that n is not included in the solution set, since the inequality is strict.
The closed circle at 4 indicates that n is included in the solution set, since the inequality is not strict.
Hence, n<-2 or n≥4 compound inequality is represented in the third graph.

Step-by-step explanation:
You can see that from 21 to 18 the difference is -3
18 to 13 is -5
13-6 is -7
See the pattern yet? The difference of the numbers are subtracted by 2 again.
-3, -5, -7, then it's -9. then -11

One angle of an isosceles triangle is three times the
measure of each of the other two angles. Find the
measures of the angles.
Answer:
36°, 36°, 108°
Step-by-step explanation:
let the 2 congruent base angles of the isosceles triangle be x
Then the vertex angle is 3x
Sum the angles and equate to 180 ( angle sum of triangle )
x + x + 3x = 180
5x = 180 ( divide both sides by 5 )
x = 36 , then
3x = 3 × 36 = 108
The angles are 36°, 36° and 108°
What is the equation of the graph
Answer:
[tex]y = 2x^2 + 1[/tex]
Step-by-step explanation:
The graph you see there is called a parabola. The general equation for the graph is as below
[tex]y = a*x^2 + b[/tex]
To find the equation we need to find the constants a and b. The constant b is just how much we're lifting the parabola by. Notice it's lifted by 1 on the y axis.
To find a it's a little more tricky. Let's use the graph to find a value for a by plugging in values we know. We know that b is 1 from the previous step, and we know that when x=1, y=3. Let's use that!
[tex]3 = a * (1)^2 + 1\\2 = a[/tex]
Awesome, we've found both values. And we can write the result.
[tex]y = 2x^2 + 1[/tex]
I'll include a plotted graph with our equation just so you can verify it is indeed the same.

ax +9 = -2x^2 +3x +1
Rewriting to standard form, we have ...
2x^2 +(a -3)x +8 = 0
The discriminant of this equation is ...
B^2 -4AC = (a -3)^2 -4(2)(8) = a^2 -6a -55
We want this to be greater than 0. Factoring, we get ...
(a -11)(a +5) > 0
This will be true for values of a that are less than -5 or greater than 11.
