It is to be noted that Option A is the most appropriate choice of origin and scale for this graph.
What is a graph?In mathematics, a graph is defined as a graphical representation or diagram that organizes facts or values. The graph's points frequently reflect the relationship between two or more objects.
Note that we are given the following:
Week: 2 3 4 5 6 7 8
Minutes: 300 450 600 750 900 1050 1200
The difference between two cumulative weeks is one week, while the difference between two cumulative minutes is 150.
Plotting the graph between minutes and weeks we can get the most suitable scale is
x-axis scale: 1 unit = 1 week
y-axis scale: 1 unit = 150 minutes
Assuming we extend the table to the left to reflect the origin, we'll obtain
Week 0 1 2...............8
Minutes 0 150 300..........1200
Hence, The origin ⇒ (0 weeks, 0 minutes)
From the above, therefore, the most suitable choice of origin and scale is:
x-axis scale: 1 unit = 1 week
y-axis scale: 1 unit = 150 minutes
origin: (0 weeks, 0 minutes)

The scale on the x-axis should be 1 unit equal to 1 week and the scale on the y- axis should be 1 unit = 150 minutes. Option A is correct.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
As observing the data, the data mentioned in the table is represents the linear relationship.
Slope of the function = 450 - 300 / 3 - 2 = 150
This implies that for 1 week there is 150 minutes on the graph of the relationship,
Thus, the scale on the x-axis should be 1 unit equal to 1 week and the scale on the y- axis should be 1 unit = 150 minutes.

The fact that Maria runs of a mile every 8 minutes means that we runs faster.
How to calculate the speed?The speed is measured as the distance with respect to the time. This will be illustrated thus:
Maria runs of a mile every 8 minutes. Althea runs 2 miles every of an hour. It should be noted that an hour is 60 minutes. That means the she runs 1 mile in (60 / 2) = 30 minutes.

Answer:
10x + 12y = 100
x + y = 9
Step-by-step explanation:
Define Variables:
Let x = the number of small boxes purchased
Let y = the number of large boxes purchased
Each small box has 10 granola bars, so small boxes have 10x granola bars.
Each large box has 12 granola bars, so large boxes have 12y granola bars. Therefore, the total number of granola bars 10x + 12y equals 100:
10x + 12y = 100
Since a total of 9 boxes were purchased, we know x + y must equal 9.
x + y = 9

Answer:
2. y = x + 13
Step-by-step explanation:
Your points are: (-4, 9) and (2, 15)
To write an equation of a line from two ordered pairs, you first find the slope (m)
To find the slope, you do y2 - y1 / x2 - x1
(-4 is x1, 9 is y1) (2 is x2, 15 is y2)
Plug in the numbers:
15 - 9 / 2 - (-4) ----------------------> 6/6 ----------> 1, m = 1
The next equation we'll use is y - y1 = m(x - x1)
and slope intercept form is y = mx + b
Pick either ordered pair to plug in the coordinates, but this time I'll use
(2, 15) -----> 2 is x1, 15 is y1
y - 15 = m(x - 2)
Since we already know the slope, m, we can simplify the equation.
y - 15 = 1(x - 2)
Distributive property
y - 15 = x - 2
Add 15 on both sides,
y = x + 13

Let u, v and w be vectors in the vector space V, and let c and d be scalars. A set S is defined as a vector space if it satisfies the following conditions:
1. u+ v ∈V
2. v + w = w + v
3. (u + v) + w = u + (v + w)

The output of the linear function is -n+3 when the input is n.
What is a slope?The slope of a line can be used to calculate its steepness. The slope or gradient of a line is a number that indicates its direction and steepness.The slope is calculated by dividing the vertical change by the horizontal change between any two distinct points on a line. The ratio is sometimes written as a quotient, which produces the same number for every two distinct points on the same line.How to find the output of the linear function?A linear equation is given by ,
f(x) = mx+ c ---(1)
From the table,
x value increases by 1
y value decreases by 1
The function's slope, or the coefficient that converts an increase in x to an increase in y, is represented by the letter m.So, the coefficient slope(m) magnifies the decrease by 1Substituting slope m = - 1 in (1)
f(x) = -x+ c ---(2)
Substitute (1, 2) in (2)
2 = -1 +c
c = 2 + 1
c = 3
Substitute slope m and c in (2)
f( x ) = - x + 3
When input is n output is given by,
f(n) = - n + 3
The output of the linear function is -n+3 when the input is n.

Answer: A) x^2+y^2 B) x^3+y^3 C) a^2b^2c^2 D) c^2/d^2
Step-by-step explanation:
For A, you add all the powers. This is because the bases are the same. Any number or letter without a visible power on top most likely means that is has a power of 1. Because this is a multiplication question, you have to add the powers. (Example n*n = n^2 or n^3*n^7 = n^10)
This is same for B.
For C, you multiply abc by abc so it's a*a, b*b, c*c. This is because they are inside a bracket. Anything inside the bracket that has a power outside the bracket is multiplied by itself.
For D, you multiply c and d so it's c*c, d*d. This is the same as C.

What is the area of the square?
Let a be the side length of the square.
Then the area of the square will be
Area of the square = a² square units
Cathy has 40 meters of fencing to build a rectangular pen for her pets.
For the maximum area of the rectangle, the length and width should be congruent.
