? = x
x + 8
9
9 + 6
Equation
x/(x + 8) = 9 / (9 + 6) Combine
Solution
x/(x + 8) = 9/15 Cross multiply
15x = 9(x + 8) Remove the brackets
15x = 9x + 72 Subtract 9x from both sides
15x - 9x = 72 Combine
6x = 72 Divide both sides by 6
6x/6 = 72/6
x = 12

The only complete ordered pair in the given table is:

Therefore, to determine the relationship between the variables, divide the amount saved by the number of months:
[tex]\implies \sf \dfrac{Amount\:saved}{Number\:of\:months}=\dfrac{\$60}{5}=\$12[/tex]
So we can assume that $12 is saved each month.
To complete the table:
Multiply the given number of months by $12 to determine the amount saved.Divide the given amount saved by $12 to determine the number of months.⇒ 3 × $12 = $36
⇒ $72 ÷ $12 = 6
⇒ 10 × $12 = $120

What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°. An isosceles triangle has two sides out of three equal.
A.) The value of n can be found by equating XY and XZ together,
XY = XZ
9n + 12 = 15n - 6
12 + 6 = 15n - 9n
18 = 6n
n = 3
Hence, the value of n is 3.
The length of different legs of the triangle is,
B.) XY = 9n + 12 = 9(3) + 12 = 27 + 12 = 39
C.) YZ = 15n - 6 = 15(3) - 6 = 45 - 6 = 39
Hence, the length of the legs XY and YZ is equal to 39 units.

Figure BORT- Figure XZGJ. What are the pairs of congruent angles?
Answer:
First option.
Step-by-step explanation:
Look at the position of letters, you don't really need to look at the picture.
BQRT ~ XZGJ means figure BQRT is similar to figure XZGJ and congruent angles are written in same order.
So first letter of BQRT is B and first letter of XZGJ is X.
That means that angle B is congruent to angle X.
You can write that as: ∠B ≅ ∠X
Second letter of BQRT is Q and second letter of XZGJ is Z.
Angle Q is congruent to angle Z.
∠Q ≅ ∠Z
And same for last two pairs of angles.
Final answer:
∡B ≅ ∡X, ∡Q ≅ ∡Z, ∡R ≅ ∡G, ∡T ≅ ∡J

The vertices of a triangle are A(2,5), B(1, 2), and C(3, 1). Find the coordinates of the image after a dilation with respect
to the origin using a scale factor of 2 and then a translation 2 units left and 1 unit up.
A" (). B" (). c" ()
The coordinates of the image after a dilation with respect to the origin is A'' (2,10), B" (0,4), C" (4,2) .
How does dilation work?Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation.
Its also called scaling of a figure, but due to the involvement of coordinates, it involves a center of a dilation, which is like a pinned point that stays at the same place after dilation.
Its like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).
The vertices of a triangle are A(2,5), B(1, 2), and C(3, 1).
A' = 2(2.5) = (4,10)
B' = 2(1,2) = (2,4)
C' = 2(3,1) = (6,2)
Translation of 2 units left means change in x
A'' = (4-2,10) = (2,10)
B" = (2-2,4) = (0,4)
C" = (6-2,2) = (4,2)
Translation of 1 units up means change in y

that graphs in the second
quadrant.
[?] (cos[]° + i sin[__ _]°)
Use degree measure.
Enter
Answer:
The answer is
[tex]2 \cos(100) + i \sin(100) [/tex]
Step-by-step explanation:
This is a complex number,
[tex]a + bi[/tex]
First, convert this to de movire form.
[tex]r( \cos( \alpha ) + i \sin( \alpha ) [/tex]
where
[tex]r = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
and
[tex] \alpha = \tan {}^{ - 1} ( \frac{b}{a} ) [/tex]
[tex]a = 4[/tex]
[tex]b = - 4 \sqrt{ 3} i[/tex]
[tex]r = \sqrt{ {4}^{2} + ( - 4 \sqrt{3}) {}^{2} } [/tex]
[tex]r = \sqrt{16 + 48} [/tex]
[tex]r = \sqrt{64} = 8[/tex]
and
[tex] \alpha = \tan {}^{ - 1} ( \frac{ - 4 \sqrt{3} }{4} ) [/tex]
[tex] \alpha = \tan {}^{ - 1} ( - \sqrt{3} ) [/tex]
Here, our a is positive and b is negative so our angle in degrees must lie in the fourth quadrant, that angle is 300 degrees.
So
[tex] \alpha = 300[/tex]
So our initially form is
[tex]8( \cos(300) + i \sin(300) )[/tex]
Now, we use the roots of unity formula. To do this, we first take the cube root of the modulus, 8,
[tex] \sqrt[3]{8} = 2[/tex]
Next, since cos and sin have a period of 360 we add 360 to each degree then we divide it by 3.
[tex] \sqrt[3]{8} ( \cos( \frac{300 + 360n}{3} ) + \sin( \frac{300 + 360n}{3} ) [/tex]
[tex]2 \cos(100 + 120n) + i \sin(100 + 120n) [/tex]
Since 100 is in the second quadrant, we let n=0,
[tex]2 \cos(100) + i \sin(100) [/tex]
find the value of A , B and C from the following figure
Step-by-step explanation:
Question 1 :Here in the given figure b and 30° are alternate to each other so it can be name as alternative angle....
b = 30°
Now...
a + 30° = 180° ( being supplementary angle )
a = 180° - 30°
a = 150°
Now the value of c will be 150° being corresponding
angle with a
c = 150°
Question 2 :z = 60° ( being alternative angle )
Now let's find the value of x.....
here ,
60° + 50° + x = 180° ( the sum of interior angle of triangle is 180°
x = 180° - 110°
x = 70°
Now...
y = 70° ( alternative angle )

Jack walked up a hill at a speed of $(x^2-11x-22)$ miles per hour. Meanwhile, Jill walked a total distance of $(x^2-3x-54)$ miles in $(x 6)$ hours. If Jack and Jill walked at the same speed, what is that speed, in miles per hour
Jack and Jills' speed in miles per hour is 4
How to determine the speed in miles per hour?The given parameters are:
Jack speed = x^2-11x-22
Jill distance = x^2-3x-54 and time = x + 6
Speed is calculated as:
Speed = Distance/time
So, we have:
Jill speed = x^2-3x-54/x + 6
Factorize the numerator
Jill speed = (x + 6)(x - 9)/x + 6
Cancel the common factor
Jill speed = x - 9
Both speeds are equal.
So, we have:
x^2-11x-22 = x - 9
Collect like terms
x^2-11x - x -22 + 9 = 0
Evaluate
x^2 - 12x - 13 = 0
Factorize the expression
(x + 1)(x - 13) = 0
Solve for x
x = -1 or x = 13
x cannot be negative.
So, we have:
x =13
Substitute x =13 in Jill speed = x - 9
Jill speed = 13 - 9
Evaluate
Jill speed = 4
Hence, their speed in miles per hour is 4
