Which is the graph of the linear inequalityx-2y> -6?
Answer:
4th graph (in bottom right corner)
Step-by-step explanation:
First, convert the given equation into slope-intercept form.
Given :-
1/2x - 2y > -6
-2y > -1/2x - 6
2y < 1/2x + 6
y < 1/4x + 3
As the < sign indicates, the line will be dotted and the solution set will be towards the origin in this case.
The correct option is the 4th graph (in bottom right corner)

The bar graph shows your cell phone data usage for five months. A vertical bar graph, titled Cell Phone Data Uses. The vertical axis is labeled Gigabytes. The horizontal axis is labeled Month. For May, the bar height is 0.9. For June, the bar height is 1.85. For July, the bar height is 3.82. For August, the bar height is 2.19. For September, the bar height is 1.24. Describe how the outlier affects the mean. 4 / 10000 Word Limit it makes it higher. Question 2 Use the data to answer the statistical question, "How much cell phone data do you use in a month?" gigabytes
The outlier of the cell phone data usage has its value to be relatively higher or lower than other values
The outlier would make the mean higherYou use 1.85 gigabytes of data monthlyHow to determine the outlier
From the bar graph, we have the following entries:
May = 0.9
June = 1.85
July = 3.82
August = 2.19
September = 1.24
The outlier of the dataset is 3.82.
This is so because it is relatively higher and far from other data elements
So, the outlier would make the mean higher
How much cellphone data you used monthlyThe outlier affects the mean, but it does not affect the median.
So, we calculate the median.
When the dataset is arranged, we have:
0.9, 1.24, 1.85, 2.19, 3.82
The middle value is 1.85.
This represents the median.
Hence, you use 1.85 gigabytes of data monthly

Explain how this graph demonstrates how the equation y = mx can be derived from the two points (1, m) and (x, y).
The equation y = mx of the graph is a linear equation
The linear equation that demonstrates the relationship on the graph is y = mx
How to determine the equation from the graphThe points on the graph are given as:
(1, m) and (x, y)
Start by calculating the slope (M)
[tex]M = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]M = \frac{y - m}{x - 1}[/tex]
The linear equation is then calculated as:
[tex]y = M(x - x_1) + y_1[/tex]
This gives
[tex]y = \frac{y - m}{x- 1}(x - 0) + 0[/tex]
[tex]y = \frac{y - m}{x- 1}(x)[/tex]
Cross multiply
[tex]yx-y = yx - mx[/tex]
Evaluate the common terms
[tex]-y =- mx[/tex]
Divide both sides by -1
y = mx
Hence, the equation of the graph is y = mx

The price of a bicycle that ms. motyka wants to buy is $282. How much will she pay for the bicycle if there is a 4% sales tax.
Answer: $293.28
Step-by-step explanation:
We know that 282 is the 100% price tag on the bicycle. And there is a 4% tax applied to the 282. So we need to find out how much is 4% of 282.
282/100% = x/4% (we don’t know how much is 4% so its represented by X.
do a cross over where you end up with this:
282 (4) = x (100) we want to have X on its own as it represents the 4% to which we are looking for the amount in dollars. So you end up with this:
282 (4) /100 = x
solve the multiplication first and then divide.
1128/100 = x
11.28 = x
so now we know 4% of 282 is $11.28 so we add it to know how much does this person pay.
$282 + $11.28 = $293.28

The Cleveland City Cable Railway had a 14-foot-diameter pulley to drive the cable. In order to keep the cable cars moving at a linear velocity of 16 miles per hour, how fast would the pulley need to turn (in revolutions per minute)? (1 mi = 5,280 ft. Round your answer to the nearest tenth.)
Answer:
32.0 rpm
Step-by-step explanation:
16 mi/h = (16 mi)(5280 ft/mi)/(60 min) = 1408 ft/min
One revolution is a distance of ...
C = πd
C = π(14 ft) ≈ 43.98 ft
So the number of revolutions per minute is ...
(1408 ft/min)/(43.98 ft/rev) = 32.01 rev/min
The pulley needed to turn at 32.0 rpm.

What are the similarities and differences between translations, reflections, and rotations?
One paragraph or more ( 5 sentences) will reward for Brainly best description!
Answer:
There are four main types of transformations: translation, rotation, reflection and dilation. A translation moves the object without rotating it or changing its size. Reflection flips the object about a line of reflection. Rotation rotates a figure about a fixed point. Dilation changes the size of a figure without changing its essential shape. When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction. Transformation can be done in a number of ways, including reflection, rotation, and translation. ~When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite.

The circumference of frisbee is 12.56 inches. What is the frisbee’s radius?
30 points please show work thank you!!
Diameter = cirumference / pie(3.14)
Radius = Diameter/ Radius
Radius is 2 inches
The radius of the frisbee with a circumference of 12.56 inches is 2 inches
Formula for circumference
C = 2πr
Where
C is the circumference
r is the radius
π is constant (i.e pi)
How to determine the radius
From the question given above, the following data were obtained:
Circumference (C) = 12.56 inPi (π) = 3.14 Radius (r) =?C = 2πr
12.56 = 2 × 3.14 × r
12.56 = 6.28 × r

For 13–17, use the table at right. The table gives the populations of Toledo, Ohio, and Lexington, Kentucky, during the last three U.S. Censuses.
Answer:
13)2000 per year
14)a_n = 350000 - 2000(n - 1)
15)3000 per year
16)a_n = 200000 + 3000(n - 1)
17)when when the number of years is more than 31 years, Lexington's population will be greater than toledo.
Step-by-step explanation:
13) From the table, the population of toledo is 350,000 in 1980 and 330000 in 1990.
Thus,population change from 1980 to 1990 is; 350000 - 330000 = 20000
Similarly, from 1990 to 2000, population went from 330000 to 310000. Change in population is; 330000 - 310000 = 20000
In both cases we see that in 10 years interval, the change is 20000 each.. Thus, for 1 year, change in population = 20000/10 = 2000 per year
14) The population of toledo after 1980 can be expressed using arithmetic progression. Formula is;
a_n = a + (n - 1)d
Where;
a is population in 1980
n is number of years after 1980
d is change in population per year.
Since the population decreases each year, then d will be negative. Thus;
Thus;. a_n = 350000 - 2000(n - 1)
15)From the table, the population of lexington is 200,000 in 1980 and 230000 in 1990.
Thus,population change from 1980 to 1990 is; 230000 - 200000 = 30000
Similarly, from 1990 to 2000, population went from 230000 to 260000. Change in population is; 260000 - 230000 = 30000
In both cases we see that in 10 years interval, the change is 30000 each.. Thus, for 1 year, change in population = 30000/10 = 3000 per year
16) like earlier stated The population of Lexington after 1980 can be expressed using arithmetic progression. Formula is;
a_n = a + (n - 1)d
Where;
a is population in 1980
n is number of years after 1980
d is change in population per year.
a_n = 200000 + 3000(n - 1)
17) we want to find the years in which the population of Lexington will be more than that of toledo.
This simply means the inequality is;
200000 + 3000(n - 1) > 350000 - 2000(n - 1)
Deduct 200000 from both sides;
200000 - 200000 + 3000(n - 1) > 350000 - 200000 - 2000(n - 1)
3000(n - 1) > 150000 - 2000(n - 1)
Add 2000(n - 1) to both sides to get;
3000(n - 1) + 2000(n - 1) > 150000
3000n - 3000 + 2000n - 2000 > 150000
5000n - 5000 > 150000
5000n > 150000 + 5000
5000n > 155000
n > 155000/5000
n > 31
Thus,when when the number of years is more than 31 years, Lexington's population will be greater than toledo.

What is the equation of the given line in standard form?
–6x + 7y = –17
–6x + 11y = –13
–11x + 6y = –13
–6x +11y = 13
Answer:
-6x + 11y = 13
Step-by-step explanation:
the equation in slope-intercept form is:
from the two points we can find the slope, 2-(-1) / 1.5-4)
slope = 6/11
y-intercept can be found by using a point and the slope:
-1 = 6/11(-4) + b
-1 = -24/11 + b
b = 1 2/11 or 13/11
so we have:
y = 6/11x + 13/11
if we multiply everything by 11 we get:
11y = 6x + 13
subtract 6x from each side to get:
-6x + 11y = 13
