Answer: System 1 has an infinite number of solutions and System II has no solutions.
Step-by-step explanation:
If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.
If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

The difference of the range and the interquartile range of the data set represented by the box plot is
.
Answer:
the answer is 10
Step-by-step explanation:
The difference between the range and the IQR of the data set represented by the box plot is 10.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
The range of a dataset is calculated as the difference between the maximum and minimum values in the dataset.
In this case, the range is:
Range = highest value - lowest value = 34 - 16 = 18
The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1). In this case, the IQR is:
IQR = Q3 - Q1 = 29 - 21 = 8
So the difference between the range and the IQR is:
Range - IQR = 18 - 8 = 10
Therefore,
The difference between the range and the IQR of the data set represented by the box plot is 10.

Step-by-step explanation:
Write an equation of the form y = mx for the line shown below.
Answer:
y = -3x
Step-by-step explanation:
To get slope intercept, you divide both y values by both x values like this
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case this will be [tex]\frac{(-3 - 6)}{(1 - (-2))}[/tex]
This will become [tex]\frac{-9}{3}[/tex]
Divide those two to get -3, and now you get your slope intercept.

The width of a rectangle measures (4d – 8) centimeters, and its length measures
(7d – 3) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
Answer:
(22d-22) cm
Step-by-step explanation:
perimeter= 2×(4d-8+7d-3)
= 2× (11d-11)
(22d - 22) cm
Answer:
(22d-22)cm
Step-by-step explanation:
Perimeter = 2 x (width + Length)
= 2 x [(4d – 8) + (7d – 3)]
= 2 x (11d-11)
= (22d-22)cm
does anyone know the answer for this?
Answer:
8 cm
Step-by-step explanation:
The area of the shaded portion is:
[tex]a = \pi \times (( {r1)}^{2} - {(r2}^{2})) [/tex]
A=39π cm^2
r1 is the radius of the large circle
r2=5 cm
So,

Answer:
[tex]-\frac{\sqrt{21}}{2}[/tex]
Step-by-step explanation:
ASTC (I use a sentence to memorize: All Students Take Calculus):
Q1 - All functions are positive
Q2 - Sine is positive (Cosecant is positive as well) (all others negative)
Q3 - Tangent is positive (Cotangent is positive as well) (all others negative)
Q4 - Cosine is positive (Secant is positive as well) (all others negative)
Applying ASTC:
Secant is negative, so it can't be in quadrant 1, and quadrant 4.
Quadrant 2 - Sine and Quadrant 3 - Tangent are left.
Cosecant is positive so it can't be in quadrant 3.
Therefore, angle x is in Quadrant 2 or QII
Secant is hypotenuse / adjacent
5 = hypotenuse (hypotenuse is never a negative number)
-2 = adjacent
use pythagorean theorem to solve for opposite (bc tan = opp / adj)
[tex](-2)^2+o^2=5^2;4+o^2=25;o^2=21;o=\sqrt{21}[/tex]
tanx = [tex]\frac{\sqrt{21}}{-2}=-\frac{\sqrt{21}}{2}[/tex]

What is the value of x?
Answer:
98 degrees
Step-by-step explanation:
first find angle G
53 + 45 + G = 180
subtract 45 and 53 from both sides
G = 82
angle g is supplementary (add up to 180) to x
x +82 = 180
subtract 82 from both sides
x = 98
Answer:
x = 98°
Step-by-step explanation:
There are 180° in a triangle, and 180° on a line.
180° - 53° - 45° = 82°
180° - 82° = 98°
The circumference of a circle is about 33.912 inches. The circle's radius is __ inches.
Use 3.14 for π.
Answer:
5.4
Step-by-step explanation:
Circumference = 2 x 3.14 x radius
To find this information, you must first divide:
33.912 ÷ 2 = 16.956
Then, divide:
16.956 ÷ 3.14 = 5.4
So then your answer is:
Radius = 5.4

Which statement best describes the association between variable X and variable Y?
Answer:
weak, negative association
Step-by-step explanation:
If variables have a strong association, the points will form a clear line/curve. Since the graph's points are scattered and fairly chaotic, we can say the association is weak.
Positive associations trend upwards and negative associations tend downwards. This graph seems to overall tend downwards, so we can say the association is negative.

What is the area of a circle that has the diameter of 4?
Answer:
Hello! answer: 12.56
Step-by-step explanation:
Area for circles is found be doing
radius × radius × pi since we arent given radius we have to figure it out. But what we do know it diameter is just 2 times the radius so to undo that to find our radius we just do 4 ÷ 2 and 4 ÷ 2 = 2 so 2 is our radius now we will square it which is just fancy for multiply is by itself so 2 × 2 = 4
4 × 3.14 = 12.56 So 12.56 is our area! Hope this helps you!
