Answer:
17.25 < 17.252
Step-by-step explanation:
17.25 means 17.250. So, 17.250 is less than 17.253, which is correct. The other answer choices are incorrect because the sign is pointed the wrong way. 29.60 is not greater than 29.65, so that's incorrect. 21.51 is greater than 21.49. That is not an answer choice though, so that answer choice is incorrect. 7.602 is not greater than 7.612, so that is incorrect.

If x²- y² = 20 and x+y = 10, then find x
Answer:
x = 6
Step-by-step explanation:
x² - y² is a difference of squares and factors as (x + y)(x - y)
given
x² - y² = 20 , then
(x + y)(x - y) = 20 ← substitute x + y = 10
10(x - y) = 20 ( divide both sides by 10 )
x - y = 2 → (1)
x + y = 10 → (2)
add (1) and (2) term by term to eliminate y
2x + 0 = 12
2x = 12 ( divide both sides by 2 )
x = 6

The equation of the circle x^2 + y^2 - 6x - 2y + 4 = 0 has a radius of √6 and a center located at (3 , 1).
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by

where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.
If the equation of the circle in general form is x^2 + y^2 - 6x - 2y + 4 = 0, then the coefficients are:

Find the center and the radius of each circle. x²+2 x+1+y²=4
The center and radius of the circle given by the equation x^2 + 2x + 1 + y^2 = 4 is (-1 , 0) and 2, respectively.
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by
x^2 + y^2 + Dx + Ey + F = 0
where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.
If the equation of the circle in general form is x^2 + 2x + 1 + y^2 = 4, then the coefficients are:
D = 2
E = 0
F = 1 - 4 = -3
If D = -2h and D = 2, then

Determine whether -FG is tangent to ®E . Justify your answer.
Line segment FG is not tangent to circle E.
What is Tangent:
The tangent is defined as a line touching circles or an ellipse at only one point. Suppose a line touches the curve at P, then the point “P” is called the point of tangency. In other words, it is defined as the line which represents the slope of a curve at that point.
What is Line Segment:
A line segment has two definite endpoints in a line. The length of the line segment is fixed, which is the distance between two fixed points. The length here can be measured by metric units such as centimeters (cm), millimeters (mm) or by conventional units like feet or inches.
Now, According to the problem
The tangent line to a circle makes an angle of 90 degrees with the radius.
If |FG| is tangent to circle E.

How to order of the angles from smallest to largest?Given: [tex]\angle[/tex] X = 90° (right angle) and [tex]\angle[/tex] W = 51°
The sum of the interior angles of any triangle is 180°, then
[tex]\angle[/tex] W + [tex]\angle[/tex] X + [tex]\angle[/tex] Y = 180°
Replacing the given values then we get
51° + 90°+ [tex]\angle[/tex] Y = 180°
141° + [tex]\angle[/tex] Y = 180°
Solving for [tex]\angle[/tex] Y
Subtracting 141° both sides of the equation:
141° + [tex]\angle[/tex] Y - 141°=180° - 141°
[tex]\angle[/tex] Y = 39°
The order of the angles from smallest to largest is:
[tex]\angle[/tex] Y = 39°, [tex]\angle[/tex] W = 51°, [tex]\angle[/tex] X = 90°

On a coordinate graph, your house is located at the origin (0,0) You leave your house and walk 6 blocks north. Then you turn and walk 22 blocks west. Since it is getting late, you decide to walk straight back home. How many blocks is it to walk straight back to your house? Round your answer to the nearest tenth
Answer:
22.8 blocks
Step-by-step explanation:
We can think of your path as traveling on a coordinate plane. You start by walking 6 units in the positive y direction, then 22 units in the negative x direction, then walking from this point (-22, 6) back to (0, 0)
This path draws a right triangle. The shorter leg is 6 units long, and the longer end is 22 units long. You want to find the hypotenuse of this triangle.
The hypotenuse is found using the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
A and B represent the sides of the triangle, and c represents the hypotenuse!
Before plugging in the functions, isolate c, since that's the answer we're looking for:
[tex]a^2+b^2=c^2\\c=\sqrt{a^2+b^2}[/tex]
Now, plug in the side lengths of the triangle:
[tex]c=\sqrt{6^2+22^2}[/tex]
Now simplify!
[tex]c=\sqrt{36+484} \\x=\sqrt{520} x=22.8[/tex]

Determine whether set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer. 7,24,25
Given set of numbers 7, 24, 25 represent a right triangle.
By the triangle inequality theorem , the sum of the lengths of any two sides should be greater than the length of the third side.
Since the sum of the lengths of any two sides is greater than that of the third side, the set of numbers are the measures of a triangle.
Now we find the type of triangle.
We find the sum of the squares of the two smaller sides, and compare the sum to the square of the largest side.
the sum of the squares of the two smaller sides is,
= 7² + 24²
= 49 + 576
= 625
= 25²
Since the sum of the squares of the two smaller sides is equal to the square of the largest side, by Pythagoras theorem the triangle must be right triangle.

Step-by-step explanation:
Summarize the possible relationships for the y -intercepts, slopes, and number of solutions in a system of two linear equations in two variables.
A consistent system of equations has at least one solution.
A consistent system is considered to be an independent system if it has a single solution, such as the example we just explored. The two lines have different slopes and intersect at one point in the plane.
A consistent system is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line. Every point on the line represents a coordinate pair that satisfies the system. Thus, there are an infinite number of solutions.
Another type of system of linear equations is an inconsistent system, which is one in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no points common to both lines; hence, there is no solution to the system.

The measure of the given angle is 10 degrees.
what are supplementary and complimentary angles?Supplementary angles are those angles that sum up to 180 degrees.
Complimentary angles are those angles that sum up to 90 degrees
The supplement of the angle is 10° more than twice it's complement.
Therefore,
180 - x = 2(90 - x) + 10
open the brackets
180 - x = 2(90 - x) + 10
180 - x = 180 - 2x + 10
180 - 180 - 10 = -2x + x
