The solution of a system is the point where the lines described by the equations of the system intersect, If a system has no solution, it is said to be inconsistent, In this case, both lines have the same slope (-3/2) which means that they are parallel each other, then they will never intersect, and the system has no solution and is inconsistent

The distance between the two given points X(-3,3) and Z(4,4) in the given cartesian plane is XZ = √50 = 7.07 units.
As per the question statement, we are supposed to calculate the distance between the two given points X(-3,3) and Z(4,4) in the given cartesian plane. We know that the distance between any two points in the plane is given by:
d=√((x2 – x1)² + (y2 – y1)²), where "d" is the distance between the points (x1,y1) and (x2,y2). Using this formula to find the distance between the two given points X(-3,3) and Z(4,4).
XZ = √((4 +3)² + (4 – 3)²)
XZ = √((7)²+ (1)²)
XZ = √(50)
XZ = 7.07 units

Explanation
We are given the following information:
• Amount at the beginning of an investment = $5500

We will determine how to evaluate the side length of a square given its area.
A square is a four sided 2D planar figure with all its sides at right angles and equal in magnitude as follows:
The side a square are all equal and will be denoted by a variable as follows:
[tex]\text{Side of a square = x}[/tex]We will now express the Area of the square in terms of its side length using the basic definition as follows:
[tex]\text{Area of square = Length}^2[/tex]We will now express the above in terms of the side length variable ( x ) as follows:
[tex]\text{Area of square = x}^2[/tex]We are given that Natasha's garden has the following area:
[tex]\text{Area of square = 4096 ft}^2[/tex]Now we will equate the result of area of a square with the side length ( x ) terms as follows:
[tex]4096=x^2[/tex]Evaluate(solve) the above the equation for the variable ( x ) by taking a square root on both sides of the equation as follows:
[tex]\begin{gathered} \sqrt{x^2}\text{ = }\sqrt{4096} \\ \textcolor{#FF7968}{x}\text{\textcolor{#FF7968}{ }}\textcolor{#FF7968}{=}\text{\textcolor{#FF7968}{ }}\textcolor{#FF7968}{\pm}\text{\textcolor{#FF7968}{ 64}} \end{gathered}[/tex]For practical sense, the variable ( x ) denotes the magnitude of the side length of the square which can not be negative. Hence, we have only solution for the side length ( x ) as follows:

Answers
Each senior citizen ticket costs $7.
One child's ticket costs $14.
Describe algebra.
Algebra is one of the numerous subfields of mathematics. The study of mathematical symbols and the rules for employing them in formulas is commonly referred to as algebra, which runs across almost all of mathematics.
S represents the senior citizen ticket cost.
C is the child's ticket cost.
Price is expressed as USD per ticket.
8S + 15C = 266
8S + 8C = 168
Subtract both equations now to get rid of S
8S + 15C = 266
8S + 8C = 168
———————————-
7C = 98
C = 98/7
C = $14
Changing the value of C in the first
8S + 15(14) = 266
8S + 210 = 266
8S = 266 - 210
8S = 56
S = 56 / 8
S = $7
Hence, $7 is the price for senior citizen
And, $14 is the price for child

How to Interpret Box and Whisker Plot?A box and whisker plot is a graph plot that indicates whether a distribution is skewed and whether there are potential unusual observations (outliers) in the data set.
Now, the way to interpret it is as follows;
The left side of the box is the lower quartile. The right side of the box is the upper quartile. The box covers the interquartile interval, where 50% of the data is found.The vertical line that split the box in two is referred to as the median. The whiskers are the two lines outside the box, that go from the minimum to the lower quartile and then from the upper quartile to the maximum.Now, looking at the box and whisker plot for January and July, we can say that those in January are approximately 10 years older than those in July.

Using linear functions, it is found that:
a) The expression to convert from Fahrenheit to Celsius is: y = 5x/9 - 160/9.
b) The inverse expression is: y = 9x/5 + 32.
What is a linear function?The slope-intercept representation of a linear function is given as follows:
y = mx + b
The coefficients of the function are described as follows:
m is the slope of the function, representing the rate of change of the output y in relation of the input x of the function.b is the y-intercept of the function, representing the numeric value of the function when the input x is of 0.For the conversion of Fahrenheit to Celsius, we have two points, as follows:
(32,0), (68, 20).
When the input increases by 36, the output increases by 20, hence the slope is calculated as follows:
m = 20/36 = 5/9
Hence:
y = 5/9x + b.
When x = 32, y = 0, hence the intercept b is calculated as follows:
0 = 5/9(32) + b
b = -5 x 32/9
b = -160/9
Hence the equation is:
y = 5/9x - 160/9.
To find the inverse expression, we exchange x and y and then isolate y, as follows:
x = 5/9y - 160/9.
5/9y = x + 160/9
5y = 9x + 160
y = 9x/5 + 32.

How to find the quadratic equation associated with given real roots and leading coefficient
In this problem we must determine the quadratic equation such that its roots are √3 + 1 / 2 and √3 - 1 / 2 and whose leading coefficient is equal to 9. This can be found by substituting on factor form:
y = a · (x - r₁) · (x - r₂)
Where:
a - Leading coefficient.r₁, r₂ - RootsIf we know that r₁ = √3 + 1 / 2, r₂ = √3 - 1 / 2 and a = 9, then the quadratic equation is:
y = 9 · (x - √3 - 1 / 2) · (x - √3 + 1 / 2)
y = 9 · [x² - (√3 - 1 / 2) · x - (√3 + 1 / 2) · x + 3 - 1 / 4]
y = 9 · (x² - 2√3 · x + 11 / 4)

The profit of the store is represented by the quadratic formula:
[tex]P(x)=-x^2+90x+52[/tex]Where
P is the profit
x is the number of videos rented
The coefficients of the parabola are:
a= -1 (coefficient of the quadratic term)
b= 90 (coefficient of the x-term)
c=52 (constant)
The value of a is negative, which indicates that the parabola opens downwards and that its maximum value is represented by the vertex.
To determine the maximum profit, you have to determine the coordinates of the vertex.
First, calculate the x-coordinate of the vertex, to do so you have to use the following formula:
[tex]x_v=-\frac{b}{2a}[/tex]Replace it with the values of the coefficients a=-1 and b=90
[tex]\begin{gathered} x_v=-\frac{90}{2\cdot(-1)} \\ x_v=-\frac{90}{-2} \\ x_v=45 \end{gathered}[/tex]Second, replace x=45 in the equation to determine the y-coordinate of the vertex:
[tex]\begin{gathered} y_v=P(45) \\ y_v=-(45^2)+90\cdot45+52 \\ y_v=-2025+4050+52 \\ y_v=2077 \end{gathered}[/tex]The y-coordinate of the vertex represents the maximum profit.
So the maximum profit is $2077, the correct option is option A.

an equation is given as y = -8.
Find:
we have to find an equation parallel to the given equation and passing through (-6, -7).
Explanation:
Compare the given equation with y = mx + b,
we find that slope ,m = 0 ,
the equation of the line passing through (-6,-7) is
y - (-7) = m( x - (-6))
y + 7 = 0(x + 6)
y + 7 = 0
y = -7
Therefore, y = -7 is an equation which is parallel to y = -8 and passing through ( -6, -7).
The graph of both y = -8 and its parallel equation y = -7 which passes through (-6, -7) is given as below
Red line represents the equation y = -8
and blue line represents the equation y = -7 passes through the point (-6,-7).
Therefore, the equation of the line parallel to y = -8 and passing through (-6,-7) is y = -7.

This means that the length RS can be calculated using the following equation
Length RS = Ratio of RS/Sum of the ratios x The length of RU
Substitute the known values in the above equation
So, we have
Length RS = 1/(1 + 1 + 4) x 54
