A dot plot displays the individual data values and a histogram displays data ranges along the x-axis and uses rectangular bars to show the frequencies of values that fall into each range.
How to illustrate the information?It should be noted that dot plots, histograms, and box plots are all common graphical ways to represent data sets.
The dot plot represents data by placing a dot for each data point. Also, the histogram groups the data into ranges and then plots the frequency that data occurs in each range.
The similarities is that the dot plot and the histogram can more easily tell us the mode of our data set. A dot plot gives you a visual idea of your data, but histogram gives you additional information.

The equation y = 1000x - 5000 represents the monthly profits of a start-up dry cleaning company. Time in months is x and profit in dollars is y. The first date of operation is when time is zero. However, preparation for opening the business began 3 months earlier with the purchase of equipment and supplies. Graph the linear function for x-values from -3 to 8
The attached graph represents the graph of the linear equation y = 1000x - 5000 on a scale of 1 to 1000 units on both axes
What are linear equations?Linear equations are equations that have constant average rates of change, slope or gradient
How to graph the linear function?The equation of the linear function is given as:
y = 1000x - 5000
The x values are given as:
x = -3 to 8
This means that the domain of the function is [-3, 8] or -3 <= x <= 8
So, we set x = -3 and x = 8, and we calculate the y values.
So, we have:
y = 1000 * -3 - 5000 = -8000
y = 1000 * 8 - 5000 = 3000
So, we draw two points at (-3, -8000) and (8, 3000) and connect the dots

On a graph, sketch f(x)=x+3 and g(x)=x. Is there a way of determining the graph of f(x)+g(x) without solving it algebraically? Explain your thinking below.
From the graph, the equation of f(x) + g(x) is f(x) + g(x) = 2x + 3
How to determine the graph of f(x) + g(x)?The functions are given as:
f(x) = x + 3
g(x) = x
From the above functions, we can see that the function g(x) is the parent function of a linear function.
When the parent function of a linear function is added to another function to form a composite function, the new function would pass through the following points
(x, y)= (0, b) and (-b, -b)
Where b is the y-intercept of the other function
i.e b = 3 from f(x) = x + 3
So, we have the following points
(0, 3) and (-3, -3)
Next, we draw the points and we connect the points

Please let me know if you have any questions
please give the answer
Step-by-step explanation:
f(a):
So for this you simply plug in "a" as x, and this doesn't really do anything beside replace all values with x, so you just have the equation:
[tex]f(a) = 5a+4[/tex]
2 f(a):
So for this one, you want to represent f(a) using the equation it's equal to (5a + 4), and substitute it in for f(a). In doing so, you get the expression:
2*f(a) -> 2(5a + 4) -> 10a + 8
f(2a):
So this is very similar to the first question, although you will have to do some multiplication. So just plug in 2a as "x" to get the equation:
[tex]f(2a) = 5(2a) + 4 = 10a+4[/tex]
f(a+2):
Basically the same process, you plug in (a+2) as "x" and simplify:
[tex]f(a+2) = 5(a+2) + 4\\f(a+2) = 10a+10+4\\f(a+2) = 10a+14[/tex]
f(a) + f(2):
This is similar to the second question, and you simply want to replace the f(a) with the equation that represents it (5a + 4) and same thing for f(2) = 5(2) + 4
[tex]f(a) + f(2) = (5a+4)+(5(2)+4) \\f(a) + f(2) = (5a+4)+(10+4)\\f(a)+f(2) = (5a+4) + (14)\\f(a) + f(2) = 5a+18[/tex]

If Hiawatha held his bow 1.5 m off the ground and shot the arrow at a 45° angle with an initial velocity of 40 m/s, then the arrow’s height (in meters) off the ground can be modeled by the equation h(t)=−9.8t2+28t+1.5.

Set the height to 3
[tex]-9.8t^2 + 28t + 1.5 = 3[/tex]
Subtract 3 from both sides
[tex]-9.8t^2 + 28t - 1.5 = 0[/tex]
Apply the following quadratic formula
[tex]t = \frac{-b \pm \sqrt{b^2- 4ac}}{2a}[/tex]
So, we have:
[tex]t = \frac{-28 \pm \sqrt{28^2- 4*-9.8*-1.5}}{2*-9.8}[/tex]
This gives
[tex]t = \frac{-28 \pm \sqrt{725.2}}{-19.6}[/tex]
This gives
[tex]t = \frac{-28 \pm 26.93}{-19.6}[/tex]
Expand
[tex]t = \frac{-28 + 26.93}{-19.6}[/tex] and [tex]t = \frac{-28 - 26.93}{-19.6}[/tex]
This gives
t = 0.054 and t = 2.80
0.054 is less than 2.80

If a trader took a loan of 1,800.00 at an interest of 12 percent per annum
a. Interest on the loan is $216.
Amount to be paid at the end of the year is $2016
Monthly Installment is $168
b. She took $2184 to the nearest dollar.
What is the Interest?a) i) Interest on the loan:
Interest = Principal × Rate × Time
Interest = $1800 × 0.12 × 1
Interest = $216
ii) Amount to be paid at the end of the year:
Amount = Principal + Interest
Amount = $1800 + $216
Amount = $2016
iii) Monthly installment:
Number of monthly installments = 12
Monthly Installment = Total Amount / Number of Installments
Monthly Installment = $2016 / 12
Monthly Installment ≈ $168
b) Let's X represent the amount she took
Total Payment = Monthly Installment × Number of Months
Total Payment = $200 × 12
Total Payment = $2400
So
Total Payment = X + $216
$2400 = X + $216
Subtract $216 from both sides:
$2400 - $216 = X
$2184 = X
Therefore she took approximately $2184 to the nearest dollar.

To eliminate the y terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before adding the equations together?
First equation: 4x − 3y = 34
Second equation: 3x + 2y = 17
Answer:
Multiply both sides of the first equation by 2.
Multiply both sides of the second equation by 3.
Step-by-step explanation:
The y terms are
-3y
2y
The LCM of 2 and 3 is 6.
We need the y terms to add to zero.
Multiply both sides of the first equation by 2 to get -6y.
Multiply both sides of the second equation by 3 to get 6y.
Then -6y + 6y = 0 eliminating the y terms after adding the equations.
