3x – 2y = -2
3x + y = 10
Answer:
x = 2 ; y= 4
Step-by-step explanation:
3x -2y = -2
y = -3x+10
3x + 6x -20 = -2
9x = 18
x = 2
y = -6 + 10
y = 4
Answer:
x = 2
y = 4
Steps:
given:
3x – 2y = -2
3x + y = 10
2y = 3x+2
y = (3x+2)/2
3x + y = 10
3x + (3x+2)/2 = 10
(6x+3x+2)/2 = 10
(9x + 2)/2 = 10
9x + 2 = 20
9x = 18
x = 2
y = 4

Make circle open
You have the right idea but the endpoint is at the wrong location. Instead, the green dot should go at -1. The shading is to the right. We use a closed filled in circle here (instead of an open hole) to tell the reader "include the endpoint". So -1 is part of the solution set.
In short, the graph consists of a closed filled in circle at -1 with shading to the right. This visually describes all values that are larger than -1, or equal to -1.

Answer:
-9
Step-by-step explanation:
(x + 89)° + (x + 109)° = 180°
(interior angles on the same side of transversal)
(2x + 198)° = 180°
2x + 198 = 180
2x = 180 - 198
2x = - 18
x = - 18/2
x = - 9

Find the value of x
classify the triangle
Hey mate.....
Step-by-step explanation:
This is ur answer.....
Triangle fixed value = 180
x = 180 - (45 + 44)
x = 180 - 89
x = 91

Follow me! :)
The value of angle x will be 91° for the given triangle.
What is a triangle?A triangle is a polygon with three sides, three vertices (corners), and three angles. The sum of the three angles in a triangle is always 180 degrees. Triangles are important in geometry and mathematics, and they have many applications in science, engineering, and everyday life.
Triangles can also be used to calculate the areas of various two-dimensional shapes and to solve problems related to distance, angles, and proportions.
Triangle fixed value = 180
x = 180 - (45 + 44)
x = 180 - 89
x = 91
Therefore, the value of x is 91°

is tangent to circle A. Determine the length of 2.
Question 4 options:
1)
5
2)
8
3)
13
4)
12
Answer:
Not sure about the question but I believe you are looking for the length of AC.
Then the answer is choice 3) 13
Step-by-step explanation:
AC² = 5² + 12² = 25 + 144 = 169
AC =√169 = 13
The required length from the point outside the circle to the point on the circle i.e. CE is 8 and the length from the point outside the circle to the center is 13.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on coordinate plane and r is the radius of the circle.
Here,
C is the point outside the circle and tangent drawn to the circle from C to B of length 12, the radius of the circle is 5. Since the radius is always perpendicular to the circle's tangent,
So
ABC is right angle triangle
AB = 5 ; BC = 12
Now applying the Pythagorean theorem
AC² = AB² + BC²
AC = √(5² + 12²)
Ac = √(25+144)
AC = √169
AC = 13
Now,
AC = AE + EC
(AE = AB)
AC = AB + EC
13 = 5 + EC
EC = 8
Thus, the required length from the point outside the circle to the point on the circle i.e. CE is 8 and the length from the point outside the circle to the center is 13.

HELP ME PLEASE!!!!
ΔAXY ~ ΔABC. What is the value of BC
Answer:
BC = 28 [tex]\frac{1}{3}[/tex] ft
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AX}{AB}[/tex] = [tex]\frac{XY}{BC}[/tex] , substitute values
[tex]\frac{12}{20}[/tex] = [tex]\frac{17}{BC}[/tex] ( cross- multiply )
12BC = 340 ( divide both sides by 12 )
BC = [tex]\frac{340}{12}[/tex] = [tex]\frac{85}{3}[/tex] = 28 [tex]\frac{1}{3}[/tex]

Answer:
x = 30
Step-by-step explanation:
multiply the fraction by 4 and the 8 by 4 because what you do to one side you have to do to the other. The 4 times the /4 cross out because you can't do math there. Now your left with x+2=32 because 4 times 8 equals 32. But you still have to keep going because we need x all alone. Now you subtract 2 form 2 and 32 from 2. The 2's cancel out and 32 minus 2 equals 30. x = 30

Find the measure of u given that pllq.
Angle u is 32°.
What are the properties of a line?A line can go on forever. The line continues forever in both directions. There are no endpoints on the lines. The following are the angles of lines: Equal angles are those that are vertically opposed, such as a = d and b = c. As an example, the angles a + b and a + c add up to 180 degrees. Angles that correspond to one other are equal, such as a = e, b = f, c = g, and d = h. A line is a geometric form with only one dimension. There is no thickness to the line; it merely has length. Lines that cross at an angle will do so only once.
Given that angle Y at the q line is 32°. Since line p and line q are parallel. From properties of a line. angle made by the same cross line with two parallel lines will be the same.
Therefore, Angle u will be the same as angle y which is 32°.
