It's worth noting that this form is known as the standard form of a linear equation, where the variables x and y appear only in the first degree and the constant term is on the right side of the equation.
What is the Quadratic Equation?
A quadratic equation is a type of polynomial equation that has the general form of ax^2 + bx + c = 0, where x is the variable, a, b, and c are constants, and a is not equal to zero. The degree of the equation is two, hence the name "quadratic".
x+1/6-y can be rewritten in terms of a,b, and c by using the following equation:
ax + by + c = 0
To get x+1/6-y in the values of a,b, and c we can rewrite the equation as follow:
a = 1, b = -1, c = -1/6
So, x+1/6-y can be written as:
1x - 1y - 1/6 = 0
or
ax + by + c = 0 where a=1, b=-1 and c=-1/6
It's worth noting that this form is known as the standard form of a linear equation, where the variables x and y appear only in the first degree and the constant term is on the right side of the equation.

two hot air balloons, one purple and one gold, took off at the same time. the purple balloon started from sea level and the gold balloon started from a hill 15 1515 meters above sea level. the gold balloon began climbing at a constant rate of 2 22 meters per second. the purple balloon began climbing at 2.5 2.52, point, 5 meters per second. after how many seconds were the balloons at the same altitude?
The balloons were never at the same altitude because the gold balloon was already 1515 meters above the purple balloon at the start.
Let t be the number of seconds since the balloons took off, and Hp(t) and Hg(t) be the altitude of the purple and gold balloons respectively at time t.
We know that:
Hp(t) = 0 + 2.5t (the purple balloon starts at sea level and climbs at a rate of 2.5 m/s)
Hg(t) = 1515 + 222t (the gold balloon starts 1515 m above sea level and climbs at a rate of 2*22 m/s)
We want to find the time t when the balloons are at the same altitude, so we can set Hp(t) = Hg(t) and solve for t:
0 + 2.5t = 1515 + 222t
2.5t = 1515 + 222t
2.5t - 222t = 1515
0.5t = 1515 - 1515
t = 0
So the balloons were never at the same altitude because the gold balloon was already 1515 meters above the purple balloon at the start.

Segment AB is tangent to ⊙T at B. What is the radius of ⊙T? Triangle ABT where T forms the centre of a circle. B is a point on the circumference of the circle. The side AT intersects the circumference at the point C. AC equals 25 and Ab equals 45.
Answer:
28
Step-by-step explanation:
AB and TB are perpendicular because the tangent and radius are perpendicular. So you have a right triangle. Triangle ABT is a right triangle.
Also, TB is a radius of the circle, but so is TC. They are the same length.
Use Pythagorean Theorem to solve this problem.

a. More than 3,000 people are killed yearly in crashes involving large trucks or buses.
The stopping distance of a large truck or bus is determined by calculating the kinetic energy (K) of the vehicle, the coefficient of friction (μ) between the road and the tires, and the weight (W) of the vehicle. The formula for calculating the stopping distance is K = (μ * W2) / 2g, where g is the acceleration due to gravity. This means that the heavier the vehicle and the lower the coefficient of friction, the longer the stopping distance. Since large trucks and buses are heavier than cars, they have a longer stopping distance and are more likely to be involved in fatal crashes.

The length of GH is about 7.3 units. The solution has been obtained by using the formula of distance between two points.
What is distance between two points?
The distance between two points in a plane is the length of the line segment separating the two points. Typically, the equation
[tex]d=\sqrt{(x_{2} -x_{1})^{2} + (y_{2} -y_{1})^{2} }[/tex] is used to calculate the distance between two points. One can use this formula to get the separation between any two points on an x-y plane or coordinate plane.
We are given two points as G(-9,-4) and H(-2,-6)
Using the distance formula,
[tex]d=\sqrt{(x_{2} -x_{1})^{2} + (y_{2} -y_{1})^{2} }[/tex]
[tex]d=\sqrt{(-2 +9)^{2} + (-6 +4)^{2} }[/tex]
[tex]d=\sqrt{(7)^{2} + (-2)^{2} }[/tex]

What is the length of every median in an equilateral triangle whose side length is 5?
The length of every median in an equilateral triangle whose side length is 5 is; 4.33
What is the length of the triangle median?In geometry, a median of a triangle is defined as a line segment joining a vertex to the midpoint of the opposite side which therefore bisects that side.
This tells us that every single triangle has exactly three medians, with one from each vertex, and as a result they all intersect each other at the centroid of the triangle.
The median joins a vertex and the opposite side's midpoint. Thus;
side = 5
half side = 5/2 = 2.5
Using Pythagoras theorem;
a² + b² = c²

A train left Vicky's town and traveled for 4 hours and 50 minutes to Wildgrove. Then it traveled 2 hours and arrived in Westminster at 12:28 P.M. What time did the train leave Vicky's town?
Answer:

Step-by-step explanation:
Since the train arrived at it's final destination at 12:28 pm and it took two hours to get there. Subtract two hours from the final destination time and it's 10:28 am. Then it took 4 hours and 50 minutes to arrive to Wildgrove, so subtract four hours of the time when the train arrived. It is now 6:28 am. Subtract fifty minutes from that and you would get 5:38 am.

Select the correct answer from the drop-down menu. Find the missing term. 7-147 × 798 = 718 × 7-38 ×
Using exponents rule the missing term in the equation 7^(-147) × 7^(98) = 7^(18) × 7^(-38) ×____ is found to be 7^(-29).
What is an exponent?
The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.
The given expression is - 7^(-147) × 7^(98) = 7^(18) × 7^(-38) ×____
Let the missing term be x.
Then the equation is -
7^(-147) × 7^(98) = 7^(18) × 7^(-38) × x
Since, the base of the exponents is same, so apply the operations on the powers of the base.
The exponent rule is - a^(b) × a^(c) = a^(b + c)
Write the equation according to the rule -
7^(-147 + 98) = 7^(18 - 38) × x
Now perform the arithmetic operation of addition and subtraction -
7^(-147 + 98) = 7^(18 - 38) × x
7^(-49) = 7^(-20) × x
The exponent rule is - a^(b) / a^(c) = a^(b - c)
Write the equation according to the rule -
x = [7^(-49)] / [7^(-20)]
x = 7^[-49 - (-20)]
x = 7^(-49 + 20)
x = 7^(-29)
Therefore, the missing term is x = 7^(-29).

How to solve simultaneous linear equations?The parameters are that the total number of five and ten-dollar bills equals 125 dollars.
Let x denote the number of five dollar bills and let y denote the number of ten dollars bills. Thus;
Total number of bills is;

Elizabeth would travel a distance of [tex]11\frac{2}{5}[/tex] miles.
The distance between Elizabeth's house and Carson's house = Sum of (the distance between Elizabeth's house and the Library + the distance between the library and Millo's house + the distance between Millo's House and Carson's House). That is:
Total Miles = [tex]6\frac{1}{2}[/tex] + [tex]2\frac{2}{5}[/tex] + [tex]2\frac{1}{2}[/tex]
To calculate the total miles, we need to transform the mixed numbers into fractions. We can do that as:
[tex]6\frac{1}{2}[/tex] = [(6 × 2) + (1)]/2 = 13/2
[tex]2\frac{2}{5}[/tex] = [(2 × 5) + (2)]/5 = 12/5
[tex]2\frac{1}{2}[/tex] = [(2 × 2) + (1)]/2 = 5/2
So, the distance from Elizabeth's house to Carson's House has 57/5 miles, and it is calculated as:
13/2 + 12/5 + 5/2 = 57/5
