Answer:
Step-by-step explanation:
12x<96. divide both sides by 12
x<8
So it would be a leftward arrow with a hollow dot at 8 because 8 is not included because x is ‘less tha’ 8
Answer:
x < 8
see attached image
Step-by-step explanation:
Start by dividing both sides by 12 (which is a positive number, so the inequality symbol stays as it is)
x < 96 / 12
x < 8
then graph it as the left side of the x-axis to the point 8, NOT including this point (use an empty dot as shown in the attached image)

write an equation of the line that passes through (2, -4) and (0, -4)
Answers
(2, -4) means 2 is your x1 and -4 is your y1
(0, -4) means 0 is your x2 and -4 is your y2
(y2-y1) = -4 - (-4) = -4 + 4 = 0
(x2-x1) = 0 - 2 = -2
0/-2 = slope of 0
Plug slope and one point into point-slope formula y-y1 = m(x - x1)
y - (-4) = 0(x - 0)
y + 4 = 0
y = -4
You have a horizontal line going through the point (0, -4)

2x + 8x - y + y = 10 + 20
Combine like terms:
10x = 30
Divide by 10:
x = 3
Plug x back in to solve for y:
2(3) - y = 10
6 - y = 10
Subtract 6:
-y = 4
Divide by -1:
y = -4
So your solution is x = 3 and y = -4 which is also written as (3, -4).

Side SQ is congruent to Side ZX.
Angle Q is congruent to Angle X.
Angle R is congruent to Angle Y.
Angle S is congruent to Angle Z.

them were recorded as follows.
11, 6, 7, 13, 1, 13, 16, 7, 13, 16
Mean :
Median :
Mode :
Range :
Answers
Answer:
Mean: 10.3
Median: 12
Mode: 13
Range: 15
Step-by-step explanation:
First, let's define what all these terms mean.
Mean is the average of all the numbers in a set of data. Median is the number in the middle of a range whenever the numbers are put in ascending order. If there are two numbers in the middle instead of one, then take the average of those two numbers. Mode is the number that occurs the most in the set of data. Range is the difference between the largest and the smallest number in a set of data.
To make things a little easier overall, let's just go ahead and put all our numbers in ascending order, which will be as follows: 1, 6, 7, 7, 11, 13, 13, 13, 16, 16.
To find the mean, just add up all the numbers and divide by how many there are. So we'll add 1 + 6 + 7 + 7... and so on to get a total of 103. Next, we'll divide that number by 10 since there are 10 students. This gives us a mean of 10.3.
Next, we'll find the median. To find this, just figure out which number(s) is in the center of your data. Since we have an even number of terms (10), we'll have two numbers in the middle, being 11 and 13. To find our median from here, just add 11 and 13 and then divide by 2. 11 + 13 = 24 and then 24 / 2 = 12. This means that our median is 12.
Next, we'll find the mode. The mode is the number that is seen the most in a set of numbers. In our set, we see that there are three 13s. Since 13 is the most frequently used number in our set, this makes it the mode.
Finally, we'll find the range. The range is just the largest number in the set minus the smallest number in the set. In our set, 16 is our largest number and 1 is our smallest. Just do 16 - 1 = 15 and we'll see that 15 is the range of the set. Hope this helps!

That's the answer
Step-by-step explanation:
No explanation
Answer: 80 meters
Step-by-step explanation:
There are two ways you could do this.
1st way (my personal way of doing it): Add 25 + 15 + 25 + 15. Then subtract that by 9 + 7 + 9 + 7 (you do this because that will find the perimeter of the open space.)
=> 25 + 15 + 25 + 15 = 80
=> 9 + 7 + 9 + 7 = 32
=> 80 - 32 = 48
2nd way: Add 25, 15, 16 and 8. (You are adding the sides that they already give you.) Then, you would find the missing sides (or the sides that don’t have a number on the .) And that would be 7 and 9. So you add the sum of those two numbers to your answer.
=> 25 + 15 + 16 + 8 = 64
=> 7 + 9 = 16
=> 64 + 16 = 80
This might be very confusing but I hope this helps :’)

Given (9,4) and (x,−11), find all x such that the distance between these two points is 17. Separate multiple answers with a comma.
Answers
Answer:
The points are (1, -11) and (17, -11).
Step-by-step explanation:
The distance between points (x1, y1) and (x2, y2) is
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
We have values for x1, y1, and y2. We leave x for x2, and we solve for x.
[tex] 17 = \sqrt{(x - 9)^2 + (-11 - 4)^2} [/tex]
Square both sides.
[tex] 289 = (x - 9)^2 + (-11 - 4)^2 [/tex]
[tex] 289 = x^2 - 18x + 81 + 225 [/tex]
[tex] x^2 - 18x + 17 = 0 [/tex]
[tex] (x - 1)(x - 17) = 0 [/tex}
[tex] x - 1 = 0 [/tex] or [tex] x - 17 = 0 [/tex]
x = 1 or x = 17
The points are (1, -11) and (17, -11).
Using distance between two points, it is found that the values are: x = 17, x = 1.
----------------------------
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
----------------------------
Points (9,4) and (x, -11).Distance of 17, thus [tex]D = 17[/tex][tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\sqrt{(x - 9)^2 + (-11 - 4)^2} = 17[/tex]
[tex](\sqrt{(x - 9)^2 + (-11 - 4)^2})^2 = 17^2[/tex]
[tex](x - 9)^2 + (-15)^2 = 289[/tex]
[tex]x^2 - 18x + 81 + 225 = 289[/tex]
[tex]x^2 - 18x + 17 = 0[/tex]
Quadratic equation with [tex]a = 1, b = -18, c = 17[/tex].
Applying Bhaskara:
[tex]\Delta = b^2 - 4ac = (-18)^2 - 4(1)(17) = 256[/tex]
[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-(-18) + \sqrt{256}}{2} = 17[/tex]
[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{-(-18) - \sqrt{256}}{2} = 1[/tex]
The values are: x = 17, x = 1.
