Cost ($)
Rocko paid $12.50 for 25 game tickets.
Louisa paid $17.50 for 35 game tickets. What
is the constant of proportionality?
The constant of proportionality is $0.50.
A mathematical constant is a significant integer whose value is determined by an explicit definition. It is frequently denoted by a symbol or by the names of mathematicians to make it easier to use in a variety of mathematical situations.
The amount paid by Rocko is $12.50 for 25 game tickets.
The amount paid by Rocko is $17.50 for 35 game tickets.
A proportional relation can be written as:
y = k × x
where k is a constant, y is the cost, and x represents the number of tickets purchased in this instance.
Substituting the values, for Rocko
$12.50 = k × 25
Therefore
k = $12.50 / 25
k = $0.50
For Louisa,
$17.50 = K × 35
K = $17.50 / 35
K = $0.50
Now, k = K
So we have the same value of the constant in both cases, which means that the constant of proportionality is k = $0.50.

What do you mean by the term matrix?Without further explanation, matrices represent linear maps and enable explicit computations in linear algebra. In mathematics, a matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions arranged in rows and columns to represent a mathematical object or a property of such an object. As a result, a significant portion of linear algebra involves the study of matrices, and the majority of the characteristics and operations of abstract linear algebra may be described in terms of matrices. The composition of linear maps, for instance, is represented by matrix multiplication.

We are given the data as:
X g(x)
10 - 16

We need to find the equation for the data.
Slope = ( - 17 + 16 ) / ( 11 - 10)
m = - 1 / 1 = - 1
Now, the equation will be:
y - y₁ = m (x - x₁)
Substituting the values, we get that:

The graphs of the equations can be obtained by finding the intercepts, and drawing a line through the intercepts.
1. Please find attached the graph of 2•x - y - 6 = 0
2. Please find attached the graph of 4•x + 2•y + 8 = 0
How can a graph be drawn using the intercepts?The graph of the linear equations using the x and y intercepts are found as follows;
1. 2•x - y - 6 = 0
Therefore;
2•x - y - 6 = 0
y = 2•x - 6
The y-intercept is given by the point where x = 0
The y-intercept is therefore;
y = 2×0 - 6 = -6
The y-intercept is y = -6The x-intercept is given by the point where y = 0
Therefore;
0 = 2•x - 6
x = 6/2 = 3
The x-intercept is at x = 3Please find attached the graph of 2•x - y - 6 = 0, created using the x and y-intercept.
2. 4•x + 2•y + 8 = 0
Therefore;
4•x + 2•y + 8 = 0
y = -(4•x + 8)/2 = -2•x - 4
y = -2•x - 4
The y-intercept is therefore;
y = -2×0 - 4 = -4
The y-intercept is y = -4
The x-intercept is therefore;
0 = -2•x - 4
x = -4/2 = -2
The x-intercept is at x = -2

Aileen is a salesperson at Lopez Sporting Goods. She is paid a monthly commission on all Little League uniforms she sells. She receives 10% of her first $2,000 in sales and 12% of the balance of her sales. Last week she earned $231.20. What was the total value of the uniforms she sold?
The total value of the uniform Aileen sold is x= 2260 on monthly Commission sells.
Given,
Let us assume the all little League uniform = x
Aileen first commission 10% of 2000$ in sales.
Aileen Second Commission 12% of (x-2000)$
Total Commission Aileen Earner = 10% ×2000 + 12% × (x-2000)
231.2 = 0.1× 2000 + 0.12× (x-2000)
231.2 = 200 + (0.12x - 240 )
231.2 = 200 + 0.12x - 240
After Transformation, we get
0.12x = 231.2 - 200 +240
0.12x = 271.2
x = 271.2/.12
x = 2260
Aileen Sell the total value of Lopez Sporting Goods Uniform is 2260.

The average speed S, in kilometers per hour, at which Laura runs depends on the temperature t, in degrees Celsius (°C), at the start of her run and can be modeled by the function S(t) = 6 + 0.2(25 - t).
The distance, D, in kilometers, that she can run in 30 minutes given that her average speed is a kilometers per hour can be modeled by the function D(x) = 0.5x.

Postal Clerks weigh each piece of mail to find a mailing cost. It costs $0.45 per ounce to mail an item. If Sara mails two items having weights of 7 ounces and 6 3/5 ounces, how much does she pay?
we get that the total cost that Sara has to pay to mail these two mails will be equal to 4 6.12.
Sara has 2 items:
Weight of 1st item = 7 ounces.
Weight of second item = 6 3/5 ounces = 33 / 5 ounces.
Total Weight of items to be mailed = 7 ounces + 33 / 5 ounces
Total Weight = 35 + 33 / 5 ounces = 68 / 5 ounces.
Now, cost of mailing 1 ounce per mail = $ 0.45
Cost of mailing 68 / 5 ounce of mails = 68 / 5 × $ 0.45
Total cost = $ 6.12
Therefore, we get that the total cost that Sara has to pay to mail these two mails will be equal to 4 6.12.

another point that lies on the graph of the parabola. Explain your reasoning.
A parabola has an axis of symmetry y =3 and passes through the point (2, 1), another point that lies on the graph of the parabola is (2,5).
Axis of symmetry:
Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object.
Given,
Axis of Symmetry y = 3.
One point = (2,1)
Here we need to find the another point that lies on the graph of the parabola.
Use the axis of symmetry.
Point given (2,1) is 2 units away from that axis, lower.
=> 1 + 2 = 3

Answer:
5,000
Step-by-step explanation:
Answer:
Money spent on playstation games per week: =$8169861
Money spent on other video games per week: = $5542467
Step-by-step explanation:
Hi to answer this first, we have to calculate how much Americans spend on non Playstation video games. So, we have to subtract the money spent on Sony Playstation games to the total money spent:
$1958904.00-$1167123.00= 791781 on other video games per day
Now, since each week has 7 days. We have to multiply each daily amount by 7.
Money spent on playstation games per week: $1167123.00 x 7=8169861
Money spent on other video games per week: $791781 x 7= 5542467
