The value of 'k' for the given system of equation kx−y=2, 6x−2y=3 has :
a. no solution is k = 3.
b. Infinitely many solution : no such value of 'k' exist.
As given in the question,
Given system of equations are :
kx−y=2
6x−2y=3
Standard form of system of equations are:
a₁x + b₁y + c₁ = 0
a₂x + b₂y + c₂ =0
a. Condition for the no solution is given by :
( a₁ /a₂ ) = (b₁ / b₂) ≠ (c₁ /c₂ )
(k/6) = ( -1/-2)≠( -2/-3)
⇒k/6 = 1/2
⇒k = 3
b. For infinitely many solution:
( a₁ /a₂ ) = (b₁ / b₂) = (c₁ /c₂ )
⇒(k/6) = ( -1/-2)=( -2/-3)
We know that ( 1/2 ) ≠ ( 2/3)
Condition does not hold true.
No such value of 'k' exist.
Therefore, the value of 'k' for the given system of equation is given by :
a. no solution is k = 3.
b. Infinitely many solution : no such value of 'k' exist.
The above question is incomplete , the complete question is :
Find the value of k for which the system of equations

What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given exponential function is f(x)=500(0.67)ˣ.
Part A: To complete table

Consider the function f(x) = 10x² - 10x.
a. Determine, without graphing, whether the function has a minimum value or a maximum value.
b. Find the minimum or maximum value and determine where it occurs.
c. Identify the function's domain and its range.
The graph is shown below.
===================================================
Explanation:
Part A)
x² is the same as x^2
The function f(x) = 10x^2-10x is the same as y = 10x^2-10x
Compare this to the template y = ax^2+bx+c to find the following
a = 10b = -10c = 0The value of 'a' is positive, which means the parabola opens upward. Furthermore, it tells us that the graph has a lowest point. There is no highest point since both parts of the parabola go upward forever.
-----------------------------
Part B)
We'll use the values of 'a' and b found earlier to get...
h = -b/(2a)
h = -(-10)/(2*10)
h = 10/20
h = 0.5
The min value therefore occurs when x = 0.5, which is the x coordinate of the vertex. The vertex being (h,k)
To find the value of k, we plug x = 0.5 into the original function.
y = 10x^2-10x
y = 10(0.5)^2-10*0.5
y = -2.5
This is the smallest the output y values can get. Therefore, it is the minimum value.
The vertex is located at (h,k) = (0.5, -2.5)
-----------------------------
Part C)
With any quadratic function, the domain is "set of all real numbers". We don't have to worry about things like...
Division by zero errors.Taking the square root of negative values.And so on.
The range is [tex]\text{y} \ge -2.5[/tex] since we found y = -2.5 to be the smallest y value possible. See part B above. So either y = -2.5 or y > -2.5
Check out the graph below. I used GeoGebra to make it, but you could use Desmos or other similar graphing tools if you prefer.

The value of x in the quadrilateral is 23.
How to find the angles of a quadrilateral?A quadrilateral is a polygon with 4 sides. The sum of interior angles in a quadrilateral is 360 degrees.
The sum of external angles of any polygon, irrespective of the number of sides is 360∘.
Therefore, the value of x of the quadrilateral can be found as follows:
6x + x + 16 + 3x - 1 + 5x = 360
combine like terms
6x + x + 3x + 5x + 16 - 1 = 360
15x = 360 - 15

A town has a population of 53,800 and shrinks at a rate of 2.5% every year. Which
equation represents the town's population after 3 years?
The population of the down represent by the equation P = 53800 [tex](1-\frac{2.5}{100})^3[/tex] and the population after 3 years is 49865.
What is rate of decrease in population?
The rate of decrease calculates a decline as a percentage of the initial sum. To determine how quickly a population is dwindling or how much money is being lost on an investment, you may want to know the rate of decrease . Knowing the initial and final amounts is necessary to compute the rate of decrease.
Here the initial population of the town is [tex]P_0[/tex] = 53800.
Population shrink rate R = 2.5%
Number of years = 3.
Now using decrease in population formula then,
P = [tex]P_0(1-\frac{R}{100})^n[/tex]
=> P = 53800 [tex](1-\frac{2.5}{100})^3[/tex]
=> P = 53800(0.975×0.975×0.975)
=> P = 49865.
Hence the population of the down represent by the equation P = 53800 [tex](1-\frac{2.5}{100})^3[/tex] and the population after 3 years is 49865.
