What is a system of equations?
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
Here, we have
Given: y = 6x+12 and y = x+47
We have to solve this equation and find the value of x and y.
y = 6x+12....(1)
y = x+47.....(2)
We put the value of y in equation (1) and we get
x + 47 = 6x + 12
6x -x = 47 -12
5x = 35
x = 7
Now, we put the value of x in equation(2) and we get
y = 7 + 47
y = 54
Hence, the value of x = 7 and y = 54.

Mr. Hansen has three sticks that measure 5 inches, 10 inches, and 17 inches. If he connects the sticks ends, will the three sticks form a triangle?
Answer:
This would not form a triangle
Step-by-step explanation:
due to the triangle inequality theorem, in order to find out if three numbers can form a triangle, you have to have each pair of numbers add up to more than the remaining number. The first combination added is 5+10 which is 15, and that is not greater than 17, so the answer is no, this is not a triangle.

Part a: y = -6x + 5 is : Not proportional.
Part b: y = 7/8x proportional: proportionality constant = 7/8.
Explain the term proportional relation?Relationships among two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, each variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.For the stated question;
Part a: y = -6x + 5
To check the proportional relation, put value of 'x' and find the corresponding value of 'y'.
The ratio = y/x must be same.
For x = 1, y = -1
y/x = -1
And, for x = 2, y = 7
y/x = 7/2
Thus, ratio is not equal, Not proportional.
Part b: y = 7/8x
For x = 1, y = 7/8
y/x = 7/8
Now, For x = 2, y = 14/8
y/x = 7/8, both ratios are equal.
Thus, y = 7/8x proportional: proportionality constant = 7/8.

Angles x and y are supplementary. angle x measures 132.54°, and angle y measures (m − 15)°. find m∠y. 47.46° 62.46° 85.08° 117.54°
The value of the angle y will be equal to 47.46. The correct option is A.
What is a supplementary angle?Supplementary angles are those that total 180 degrees. Angles 130° and 50°, for example, are supplementary angles because the sum of 130° and 50° equals 180°.
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that the angle x is equal to 132.54°. The value of the angle y will be calculated as,
x + y = 180
132.54 + y = 180
y = 180 - 132.54
y = 47.46
Therefore, the value of the angle y will be equal to 47.46. The correct option is A.

On average a customer waits 10 minutes in a queue.
We need to find the number of customers waiting in the queue on average.
Assume that the average number of customers waiting in the queue is N.
We have the average Rate of Arrival = 2 customers per minute
So, by the formula for average waiting time under the Single-Server Queue Model,

What is trigonometry?A branch of mathematics called trigonometry examines the connections between triangles' angles and sides. It is predicated on the idea of right triangles, where one angle is 90 degrees and two sides are perpendicular to one another. The six fundamental functions of trigonometry—sine, cosine, tangent, cotangent, secant, cosecant. These values of functions can be used to address real-world angle and length issues, such as determining the height of a structure or the distance between two locations. Calculus, geometry, and other areas of mathematics are all strongly connected to trigonometry.Modeling actual phenomena like item motion, wave behaviour, and light dispersion is possible with these functions. Physics, engineering, and astronomy are just a few of the disciplines that use trigonometry extensively.

What is an exponential function?The standard definition of an exponential function is given as follows:

In which the coefficients of the function are described as follows:
a is the y-intercept, the value of y at which the function crosses the y-axis.b is the rate of change of the exponential function.Function h(x) is defined as follows:
h(x) = 3^x - 2.
For the graphed function g(x), when x = 0, y = 4, hence the intercept of the function is given as follows:
a = 4.
When x = 1, y = 5, hence the rate of change of the function is obtained as follows:
b = 5/4.
b = 1.25.
Then function g(x) is given as follows:
g(x) = 4(1.25)^x.
Due to the higher intercept, g(x) ≥ h( x) at x = 0. This will change when they intersect, which from the image given at the end of the answer is at x = 1.906, which is approximately 2, hence statement B is correct.
