The numbers -28 = -28 are representing the reflexive property.
What is reflexive property?According to the Reflexive Property, x=x for every real number x. The meaning of the reflexive property is that the two expressions will have identical answers.
Suppose for square the two expressions for the length are 2x - 2 and ( 4x / 2 - 2 ). The two lengths of the square will have the same value.
2x - 2 = ( 4x / 2 - 2 ).
2x - 2 = 2x - 2
This is called reflexive property. Therefore, the numbers -28 = -28 are representing the reflexive property.

Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour. What is Nina's
rate in miles per hour if there are 5,280 feet in a mile?
Which girl bikes faster?
Nina's rate in miles per hour is 12.711 and Nina bikes faster than Sophia.
Nina's speed can also be defined as her Average Speed.
Similarly, Sophias's speed can also be defined as her Average Speed.
We have Sophia's speed = 10 miles in hour = 10 miles per hour
What is average speed and average?
Average speed is the total distance travelled by an object to the total time taken. means,
[tex]Average Speed = \frac{Total Distance}{Total Time }\\[/tex]
Total Distance covered by Nina = 63,360ft.
[tex]1 \ mile = 5280 \ feet\\[/tex]
So,Nina's Distance (in miles) [tex]\frac{63360}{5280}= 12 \ miles[/tex]

What is mid points of line?
A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.If M is the midpoint of AB it means AM is equal to MB
AM = 3x + 8 and MB = 6x-4
and AB = AM + MB
first find the value of x by using AM = MB
6x-4 = 8x-10
-4 + 10 = 8x - 6x
6 = 2x
x = 3
AB = 6( 3 ) - 4
= 18 - 4 = 14 = MB
AB = AM + MB

The equation relating the circumference (CA) of ®A to the circumference (CB) of ®B is a(CA) - b(CB) = 0.
What is scale factor?A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object.
Now it is given that,
scale factor from ®A to ®B = b/a
⇒Ks = b/a
∵ Ks = A/B
By comparison we get,
A = b
and B = a
Thus, circumference (CA) of ®A = 2πr = 2πb
and, circumference (CB) of ®B = 2πr = 2πa
Dividing both we get,
circumference (CA) of ®A/circumference (CB) of ®B = b/a
by cross multiplication we get,
a * circumference (CA) of ®A = b * circumference (CB) of ®B
or, a * circumference (CA) of ®A - b * circumference (CB) of ®B = 0
or, a(CA) - b(CB) = 0

The equation of the circle x^2 + y^2 = 14 has a radius of √14 and a center located at (0 , 0).
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.

The slope-intercept form of the given equation of a line is: y = 3/2(x) + 7/2 The slope here, is 3/2 and y-intercept is 7/2.
What is the equation of a line to the curve?A line's equation has the standard form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c. It is a first-order equation with the variables x and y. The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.Now,
The slope-intercept form of an equation of a line is given by: y = mx + c, where m = slope of the line and c = y-intercept of the line.
Transforming the given equation of the line: -3x + 2y = 7
=> 2y = 7 + 3x
=> y = 3/2(x) + 7/2
On comparing it with y = mx + c, we get that: m (slope) = 3/2 and c = 7/2 (y-intercept).
Hence, The slope-intercept form of the given equation of a line is: y = 3/2(x) + 7/2. The slope here, is 3/2 and y-intercept is 7/2.
