Some of the coordinates on the graph are (0, -15), (1, -13), (2, -11).
The graph of the equation is given below.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The coordinates of the equation y + 7 = 2 (x - 4).
y + 7 = 2 (x - 4)
y = 2(x - 4) - 7
y = 2x - 8 - 7
y = 2x - 15
For x = 0,
y = - 15
(0, -15)
For x = 1,
y = 2 - 15 = -13
(1, -13)
For x = 2,
y = 4 - 15 = -11
(2, -11)
And so on...

Explain three of seven phases of the impulse purchase cycle
Answers
Three of the seven phases of the impulse purchase cycle. The other phases include antecedent, search, and selection.
The impulse purchase cycle is a model that describes the process of making an impulsive purchase. It is typically divided into seven phases:
Antecedent: This phase is characterized by a need or desire for something. It can be triggered by a variety of factors, such as boredom, hunger, or a sudden craving for a particular product.
Search: In this phase, the consumer begins to actively search for a product that will satisfy their need or desire. They may search online or in physical stores, and they may consider various options before deciding on a product.
Selection: In this phase, the consumer narrows down their options and selects a specific product that they want to purchase. They may consider factors such as price, quality, and convenience when making their decision.

One week, 100 tudent purchaed item from the tudent tore and the tore made a profit of $500. The next week, when 80 tudent purchaed item, the profit wa $460. Write a linear equation relating profit, to the number of tudent,
Answers
A linear equation relating profit, to the number of student is shown below.
y = 2x + 500
Linear equation is used to present the elements in mathematic. A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
To write a linear equation relating profit to the number of students, we need to find the slope and the y-intercept of the line.
The slope of the line can be calculated using the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
In this case, we can use the two data points given to find the slope:
slope = (460 - 500) / (80 - 100) = -40/ -20 = 2
The y-intercept of the line is the point where the line crosses the y-axis, which is the profit when the number of students is 0. In this case, the y-intercept is 500, since that is the profit when 100 students purchase items.
Using these values, we can write the linear equation in slope-intercept form:
y = 2x + 500
This equation can be interpreted as follows: the profit (y) is equal to 2 times the number of students (x) plus 500.

The volume of a spherical balloon (V=4/3pir^3) is increasing at a constant rate of 0.78 inches per minute. At the instant when the radius is 3.20 inches, the radius is
increasing at a rate of…
Answers
The rate at which the radius is increasing is; 0.006 in/min
How to find the rate of increase of radius?We are given that the formula for the volume of a spherical balloon is;
V = ⁴/₃πr³
where r is the radius
The volume is increasing at the constant rate of 0.78 inches per minute. Thus;
dV/dt = 0.78
Now, differentiating with respect to t gives;
dV/dt = ⁴/₃(3πr²)(dr/dt)
At radius of 3.2 inches, we have;
0.78 = 4π * 3.2² * dr/dt
dr/dt = 0.78/(4π * 3.2²)
dr/dt = 0.006 in/min

(9, 13, 14, 15, 20}
Answers
Answer:
B
Step-by-step explanation:
For a set of data to have a median that is greater than the mean, it must have an odd number of values and be skewed to the right. This means that the majority of the values in the set must be smaller than the median, with a few larger values on the right side of the distribution.
Out of the given options, the only set of data that satisfies these conditions is (B) {8, 12, 14, 14, 22}. This set has an odd number of values, and the median of 14 is greater than the mean of 14.4. The other options have either an even number of values, or are not skewed to the right.
Therefore, the correct answer is (B) {8, 12, 14, 14, 22}.

c(x) = 5. 50x 20. 50
c(x) = 5. 50 21. 60x
c(x) = 5. 50x 21. 60
Answers
The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.
The total cost for ordering 5 tickets is $108.00. This means that each ticket costs $20.50 plus a service fee of $5.50.
Therefore, we can create a linear function that represents the total cost when x tickets are ordered. The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.
When x = 5, then c(x) = 5.50 + 21.60x = 5.50 + 21.60(5) = 108.00, which matches the given total cost.

Answers
The subtotal is $20, Savings is $ 1, New Subtotal is $19, Sales tax is $1.14 and the Total is $20.14
How to determine the subtotal?
A sales discount is a reduced price offered by a business on a product or service

1 bottle of lotion = $5
1 t-shirt = $12
1 birthday card = $3
Subtotal = $5 + $12 + $3 = $20
If you use your Target RedCard and save 5%, savings will be:
Savings = 5% of Subtotal
Savings = 5/100 × $20 = $1
New Subtotal: $20 - $1 = $19
Sales tax is 6%: 6/100 × $19 = $1.14

sketch the curve with equation x2/3 + y2/3 = 4 and use symmetry to find its length.
Answers
The equation x²/3 + y²/3 = 4 represents an ellipse in the shown graph below and the length of the given ellipse is 8 units.
The equation x²/3 + y²/3 = 4 represents an ellipse centered at the origin with a major axis along the x-axis and a minor axis along the y-axis.
The equation can be rewritten as x²/4 + y²/12 = 1 to highlight the lengths of the semi-major and semi-minor axes.
The semi-major axis length is given by the square root of the denominator of the x-term, which is 4, so the semi-major axis length is 2.
The semi-minor axis length is given by the square root of the denominator of the y-term, which is 12, so the semi-minor axis length is 2√3.
Based on the symmetry of the ellipse, we can determine that it is symmetric with respect to both the x-axis and the y-axis.
This means that the length of the entire ellipse can be found by multiplying the semi-major axis length by 4, since there are 4 identical sections due to symmetry.
Length of the ellipse = 4 * semi-major axis length
= 4 * 2
= 8.
Therefore, the length of the given ellipse is 8 units.

18 years = 76.5% interest rate
76.5% = 0.765
Take 1200 times 0.765 = $918.00

Lee i packing a truck with mall and large filing cabinet. The large cabinet weigh 30 pound, and the mall cabinet weight 20 pound. To optimize the load, the total load weight hould be 1550 pound from a total of 65 cabinet. How many of each ize of cabinet hould Lee pack in the truck?
Answers
The number of cabinets of large size Lee should pack is equal to 40 and that of small size is equal to 25.
To determine how many of each size of cabinet Lee should pack in the truck, you can set up a system of equations. Let X be the number of large cabinets and Y be the number of small cabinets.
The total weight of the large cabinets is 30X pounds, and the total weight of the small cabinets is 20Y pounds. The total weight of all the cabinets is 1550 pounds, so the equation to represent this is:
30X + 20Y = 1550
The total number of cabinets is the sum of the number of large cabinets and the number of small cabinets, so the equation to represent this is:
X + Y = 65
To solve this system of equations, you can use the substitution method. First, solve for X in the second equation by substituting 65 - Y for X:
X = 65 - Y
Then, substitute 65 - Y for X in the first equation:
30(65 - Y) + 20Y = 1550
Solving this equation for Y, you get:
Y = 25
Substituting this value for Y in the second equation, you get:
X = 65 - 25 = 40
So, Lee should pack 40 large cabinets and 25 small cabinets in the truck.
