Use the number line below, where RS=6y+3, ST=4y+8, and RT=61.
a. What is the value of y?
b. Find RS and ST.
Using the number line below, where RS=6y+3, ST=4y+8, and RT=61, the value of y was found to be 4.
what is line segments ?An area of a line that can connect two points is known as a line segment. A and B, the ends of this line segment, both have fixed lengths. The separation between endpoints A and B is the length of this line segment. An area or portion of a line with two endpoints is known as a line segment. A line segment has a set length as opposed to a line. Both metric measurements, such as millimeters and centimeters, as well as conventional units, such as feet or inches, can be used to measure the length of a line segment. The length of one line segment in comparison to the other when there are two can be determined just by glancing at them. The line segment CD is longer than AB, as can be seen.
given
ST = 2y + 9 RS = 7y + 3
RT = 14y - 8
S lies between R and T, hence we can deduce that:
RS plus ST = RT
Therefore, we can swap out the equations for each of the segments above to obtain:
We can now solve this for y; to do so, let's move all the phrases that begin with y to the left.
14y -7y - 2y = 3 + 9 + 8\s(14 - 7 - 2) (14 - 7 - 2)
*y = 20
5*y = 20
y = 20/5 = 4\
y = 4
The value of y was determined to be 4.

Noah is 1.35 meters tall. At 10 a.m., he measures the length of a tree's shadow to be 31.55 meters. He stands 26.2 meters away from the tree, so that the tip of his shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
Answer:
3.64 meters
Step-by-step explanation:
To find the height of the tree to the nearest hundredth of a meter, you can use the principle of similar triangles.
First, we can use the Pythagorean theorem to find the length of the hypotenuse of the right triangle formed by the height of the tree, the distance between the base of the tree and the point where the shadows meet, and the length of the shadow of the tree.
c = √(a² + b²)
c = √(h² + 26.2²)
Next, we can use the similar triangles to establish a ratio between the length of the shadow and the height of the tree and the length of the shadow and the distance from the tree.
shadow tree / height tree = shadow person / height person
31.55 / h = 31.55 / 26.2
Now, we can cross-multiply and divide to solve for h
h = 31.55 * 1.35 / 26.2
h = 3.64 meters
We can round it up to the nearest hundredth of a meter:
h = 3.64 meters
Therefore, the height of the tree is 3.64 meters to the nearest hundredth of a meter.

Higher Order Thinking Lauren has a stamp collection. She gives Kristen 12 stamps and Ethan 15 stamps. Lauren has 22 stamps left. How many stamps did she have at the start?
Answer: 49 Stamps
Step-by-step explanation:
If Lauren gave Kristen and Ethan 12 stamps and 15 stamps respectively, that means that she gave them a total of 27 stamps. This leaves her with 22 stamps left. In order to find the number of stamps she had at the start, add the stamps she gave away to the stamps she had left at the end. So,
15 stamps + 12 stamps + 22 stamps = 49 stamps total at the start
Lauren had 49 stamps in the beginning. Since she gives Kristen 12 stamps, and Ethan 15 stamps, we can add both amounts to assume the total number of stamps she gave away. 15+12=27, so she gave away 27 stamps. Lauren was left with 22 stamps. We can add 22 to 27 to find out how many stamps she had in all. 27+22=49. Therefore, we can come to the conclusion that Lauren had 49 stamps at the start.

What is the system of equations?
A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and graphical solutions are possible for these equations. The point of intersection of two lines represents the system of equations' solution.
Line 1
Taking two points on this line (0,300) and (4,450)
Equation of line y = mx+c
m = [tex]\frac{450 - 300}{4 - 0}[/tex] = 37.5
y = 37.5x + c
Substituting (0,300) in the above equation
300 = 37.5 * 0 + c
c = 300
Line equation y = 37.5x + 300
Line 2
Taking two points on this line (0,400) and (5,500)
m = [tex]\frac{500 - 400}{5 - 0}[/tex] = 20
y = 20x + c
Substituting (0,400) in the above equation
400 = 250* 0 + c
c = 400
Line equation y = 20x + 400
a) The solution of the system is when both lines coincide

Graph -3x2+12y2=84 . What Are The Domain And Range?
The domain and range of the given graph function is R.
The equation -3x^2 + 12y^2 = 84 represents an ellipse in the coordinate plane. The standard form of an ellipse is (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axis, respectively.
To put the given equation in standard form, we need to divide both sides by 84, and divide the x^2 and y^2 by the square of their respective coefficient:
(-3/84)x^2 + (12/84)y^2 = 1
This gives us x^2/ (84/-3)^2 + y^2/ (84/12)^2 = 1
Which gives us x^2/28 + y^2/7 = 1
This means that the semi-major axis has a length of 2sqrt(7) and the semi-minor axis has a length of sqrt(7).
The domain of this function is all real numbers, because the x values can take any real value.
The range of this function is also all real numbers, because the y values can take any real value, within the boundaries of the ellipse.
So, the domain and range of the function -3x^2 + 12y^2 = 84 is all real numbers.
