In order to solve, you can use substitution. This means that you use one equation and solve for one variable, then use that one equation and plug it into the other equation. Here's how we'd do it:
WORK:
x = 12 - y (since x is already solved for, we'll use that to plug into the other given equation.
2(12 - y) + 3y = 29 (using substitution)
24 - 2y + 3y = 29
24 + y = 29
y = 5
Plug the value of y back into the first equation
x = 12 - 5
x = 7
ANSWER:
A - x = 7, y = 5

Answers
Answer:
Part A: The center of The inscribed circle is the point S
Part B: The center of The circumscribed circle is the point P
Step-by-step explanation:
Part A: Find the center of The inscribed circle of ΔABC
The inscribed circle will touch each of the three sides of the triangle in exactly one point,
The center of the inscribed circle is the point of intersection between the angle bisectors of the triangle.
So, According to the previous definition:
A₁A₂ and B₁B₂ are the angle bisectors of ∠A and ∠B
So, the inter section between them is the center of The inscribed circle
So, the center of The inscribed circle is the point S
=====================================================
Part B: Find the center of The circumscribed circle of ΔABC
The circumscribed circle is the circle that passes through all three vertices of the triangle.
The center of the circumscribed circle is the point of intersection between the perpendicular bisectors of the sides.
So, According to the previous definition:
P₁P₂ and Q₁Q₂ are the perpendicular bisectors of AB and BC
So, the inter section between them is the center of The circumscribed circle
So, the center of The circumscribed circle is the point P

Which statement describes if there is an extraneous solution to the equation √x-3 = x-5? A. there are no solutions to the equation, B. the extraneous solution is x = 7, C. the valid solutions are x = 7 and x = 4, or D. the extraneous solution is x = 4
Answers
Lets solve our equation to find out what is the extraneous solution:
[tex] \sqrt{x-3} =x-5[/tex]
[tex](\sqrt{x-3})^2 =(x-5)^2[/tex]
[tex]x-3=x^2-10x+25[/tex]
[tex]x^2-11x+28=0[/tex]
[tex](x-4)(x-7)=0[/tex]
[tex]x-4=0[/tex] and [tex]x-7=0[/tex]
[tex]x=4[/tex] and [tex]x=7[/tex]
So, the solutions of our equation are [tex]x=4[/tex] and [tex]x=7[/tex]. Lets replace each solution in our original equation to check if they are valid solutions:
- For [tex]x=7[/tex]
[tex] \sqrt{x-3} =x-5[/tex]
[tex]\sqrt{7-3} =7-5[/tex]
[tex] \sqrt{4} =2[/tex]
[tex]2=2[/tex]
We can conclude that 7 is a valid solution of the equation.
- For [tex]x=4[/tex]
[tex] \sqrt{x-3} =x-5[/tex]
[tex]\sqrt{4-3} =4-5[/tex]
[tex] \sqrt{1} =1[/tex]
[tex]1 \neq 1[/tex]
We can conclude that 4 is not a valid solution of the equation; therefore, 4 is a extraneous solution.
We can conclude that the correct answer is: D. the extraneous solution is x = 4
Answer:
D. the extraneous solution is x = 4
Step-by-step explanation:
You want to know the statement that describes if there is an extraneous solution to the equation √x-3 = x-5.
SolutionA straightforward (blind) solution to the problem proceeds by squaring both sides and solving the quadratic:
x -3 = x² -10x +25
x² -11x +28 = 0
(x -7)(x -4) = 0 ⇒ x = 4 or x = 7
When you try these solutions in the original equation, you get ...
√(4 -3) = 4 -5 ⇒ 1 = -1 . . . . . x = 4 is an extraneous solution, choice D
√(7 -3) = 7 -5 ⇒ 2 = 2 . . . . . x = 7 is the solution
DomainThe square root function is only defined for non-negative values, so the left side of the equation is only defined for x ≥ 3.
The left side of the equation produces non-negative values. The right side of the equation will have non-negative values only for x ≥ 5.
Considering the domain of the equation is x ≥ 5, we know that x = 4 cannot be a solution. It can be ignored. This value only arises because squaring the radical allows values of x that require the root to be negative.
__
Additional comment
The attached graph shows the only solution is x=7, the value that makes the difference between the sides of the equation be zero. We find it useful to write radical equations in the form f(x) = 0, making the x-intercepts of the graph of f(x) be the solution(s). The graphing calculator does not graph the function where it is undefined, so the domain restrictions are automatically accommodated.

If lines L and M are parallel in the given diagram and angle 5 is 132°, what is the measure of angle 3?
Answers
The answer is 48 degrees.
How I got my answer:
Angle 5 + Angle 3 = 180(Co. Interior Angles)
let Angle 3 be x
132 + x = 180
x = 180 - 132
x = 48
The measure of Angle 3 is 48 degrees.

a. 9g - 3
b. 3g - 9
c. g - 4g
d. 3g + 9
Answer:
a. 9g - 3
Step-by-step explanation:
Sal scored g number of goals this season . Ben has scored 4 times as many goals as Sal . Chun has scored 3 fewer goals than Ben. There goals can be expressed as follows
Sal's goal = g
Ben's goal = 4(g) = 4 × g = 4g
Chun's goal = 4g - 3
sum of their goals = g + 4g + (4g - 3)
sum of their goals = g + 4g + 4g - 3
sum of their goals = 9g - 3
if the length of an arc is 12π inches and the radius of the circle us 10 inches, what is the measure of the arc?
Answers
Thus, s = (12pi inches) = (10 inches)(theta), so
theta = the central angle (not the measure of the arc) = (12pi)/(10 inches), or
theta = 1.2*pi (no units of measurement)
Answer:
The measure of arc is 216°
Step-by-step explanation:
Length of arc, L = 12π inches
Radius of the circle, R = 10 inches
Formula: [tex]\theta=\dfrac{L}{R}[/tex]
Where, [tex]\theta[/tex] in radian.
By substituting L and R into formula.
[tex]\theta=\dfrac{12\pi}{10}[/tex]
[tex]\theta=\dfrac{6\pi}{5}[/tex]
Now we change radian to degree
[tex]\text{Degree }=\dfrac{\text{Radian}}{\pi}\times 180^\circ[/tex]
[tex]\text{Degree }=\dfrac{6\pi}{5\pi}\times 180^\circ[/tex]
Central angle = 216°
Hence, The measure of arc is 216°

How many sides does a regular polygon have if each exterior angle measures 30?
Answers
The number of sides that the polygon with each exterior angle measuring 30° has is 12.
What is a polygon?A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of all the exterior angles of a regular polygon is always equal to 360°. Therefore, the measure of an exterior angle for a regular polygon is given as,
[tex]\theta = \dfrac{360^o}{n}[/tex]
where n is the number of sides.
Given that the measure of the exterior angle is 30°. Therefore, the number of sides will be,

To find the perimeter of the given quadrilateral, calculate the distance between each pair of consecutive points using the distance formula and sum these distances. The perimeter is the sum of √17 + √20 + 3 + 2 which is 13.59 units.
Explanation:
The question you've asked involves finding the perimeter of a four-sided figure, known as a quadrilateral, with vertices R, S, T, and U located at (-1, 3), (-2, 7), (2, 5), and (-1, 5) respectively. To find the perimeter of this shape, we need to calculate the distance between each pair of consecutive vertices and sum these distances up.
Firstly, use the distance formula – d = √((x2 - x1)² + (y2 - y1)²) – to calculate the length of each side:
RS = √((-2 - (-1))² + (7 - 3)²) = √(1 + 16) = √17=4.12
ST = √((2 - (-2))² + (5 - 7)²) = √(16 + 4) = √20 = 4.47
TU = √((-1 - 2)² + (5 - 5)²) = √(9 + 0) = 3
UR = √((-1 - (-1))² + (3 - 5)²) = √(0 + 4) = 2
Finally, sum these distances to find the perimeter: √17 + √20 + 3 + 2 which comes out to be 13.59 units. The exact perimeter involves square roots since we're dealing with irrational distances.

A section in a stained glass window is shaped like a trapezoid. The top base is 1 centimeter and the bottom base is 3.5 centimeters long. If the area of the section of glass is 8.1 square centimeters, how tall is the section?
Answers
The height of the trapezoidal section is approximately 3.6 centimeters.
Explanation:To find the height of the trapezoidal section, we can use the formula for the area of a trapezoid: A = 1/2 * (top base + bottom base) * height. In this case, the top base is 1 centimeter and the bottom base is 3.5 centimeters. We are given that the area is 8.1 square centimeters. Plugging these values into the formula:
Therefore, the height of the trapezoidal section is approximately 3.6 centimeters.
The height of the trapezoidal section of stained glass is calculated using the area formula for trapezoids. With the given measurements, the height is found to be 3.6 centimeters.
Explanation:To find the height of a trapezoid section in a stained glass window with a top base of 1 centimeter, a bottom base of 3.5 centimeters, and an area of 8.1 square centimeters, we use the formula for the area of a trapezoid, which is Area = 1/2 × (base1 + base2) × height. In this case, base1 is the top base, base2 is the bottom base, and Area is already given as 8.1 cm2.
Plugging the values into the formula gives us:
8.1 = 1/2 × (1 + 3.5) × height
8.1 = 1/2 × 4.5 × height
8.1 = 2.25 × height
To find the height, we divide both sides by 2.25:
height = 8.1 / 2.25
height = 3.6 centimeters
Thus, the height of the trapezoid section is 3.6 centimeters.
