Answer:
Domain (-3, 4, 5)
Range (1, 2, 6)
Step-by-step explanation:
Domain is your x so all of the values that can go into a relation or function (which is your input) are called Domain. Domain is also all of the set of elements of ordered pair ( which is the x coordinates).
Range is your y so all the values that can go into a relation or function ( which is your output) are called Range. Range is also all the set of second elements of ordered pair ( which is the y coordinates).
So, basically you just look at all the number that come first so say you have
(1,2), (2,3), (3,4)
Your first numbers to each point are (1, 2, 3) which is your Domain
then look at the second number which are (2, 3, 4) which is your Range.

27x + 45y and 7(9x + 7y) are these equivalent?
Answer:
No
Step-by-step explanation:
If you want to know whether they are equivalent or no, we will first have to find the value of both.
[tex]27x+45y[/tex]
Since there aren't any like terms here, your answer would be
[tex]27x+45y[/tex]
Let's solve for next one.
[tex]7(9x+7y)[/tex]
Let's add in parenthesis to 7.
[tex](7)(9x+7y)[/tex]
Now we will separate everything. And also you will have to add.
[tex](7)(9x)+(7)(7y)[/tex]
Now that we added we got our answer.
[tex]63x+49y[/tex]
Both values were not the same, so therefore, your answer is no, they are not equivalent.
Hope this helps!

The sorting of the dataset and the information from the five number summary, which includes the three quartiles and the minimum and maximum values indicates that we get;
1. 2.8, 4, 4.3, 6, 7.5, 8.5, 9, 11.6, 12, 12.1
2. The interquartile range is; 7.745
What is the five number summary of interquartile range of a data set?The five number summary includes the first, second and third quartiles, Q₁, Q₂, and Q₃, and maximum and minimum values of the dataset, which serves to describe the characteristics of the data.
here, we have,
1. The sorted data from least to greatest can be presented as follows;
2.8, 4, 4.3, 6, 7.5, 8.5, 9, 11.6, 12, 12.1
Therefore, the original data in the question is already sorted from least to the greatest
2. The interquartile range, IQR, is the the difference between the third quartile, Q₃, and the first quartiles, Q₁, of the data.
IQR = Q₃ - Q₁
The dataset indicates that we get;
The number of datapoints in the dataset, n = 10
The first quartile = The (N + 1)/4 percentile value
First quartile, Q₁ = (10 + 1)/4 × 10 = The 2.75th value
The 2.75th value is the value 0.75 = 3/4 larger than the 2nd value, which can be found as follows;
Q₁ = The 2.75th value = 4 + (4.3 - 4) × (3/4) = 4.225
The third quartile, Q₃ = The (N + 1) × (3/40th value, therefore;
Q₃ = The (10 + 1) × (3/4)th value = The 8.25th value (The value 0.25th more than the 8th value )
Q₃ = 11.6 + (12 - 11.6) × 0.25 = 11.7
The interquartile range, IQR = 11.7 - 4.225 = 7.475
The interquartile range = 7.475

You borrow $350 from your aunt and agree to repay her $400 ($350 principal + $50 interest) in 18 months. What interest rate (using simple interest, and to the nearest tenth) are you paying?
Answer:
The interest rate is 0.79% per month.
Step-by-step explanation:
Present value of borrowed amount = $350
Future value of borrowed amount = $400
Interest amount = $50
Time duration = 18 months or 1.5 years
Now we have to find the rate of interest by using the above information. Here below is the calculation of interest rate.
Interest rate = P×R×T
50 = 350 × R×18
R = 0.007936
Or, R = 0.79% per month.

Since Ray QR is a bisector you can determine that PRQ and QRS are equal angles (def. of a bisector). Then, what I chose to do is graph them and find where they intercept which was 22. We now know 22 is x so we can substitute it into the equation and solve to deterine that our answer is 106.
3/4 x - 1/2 - 4 = 12
Answer: x=22

Step 1: Simplify both sides of the equation.
Step 2: Add 9/2 to both sides.
Step 3: Multiply both sides by 4/3.

What is the smallest positive number that is prime and 10 less than a perfect square?
Answer:
The problem states that the answer cannot be a perfect square or have prime factors less than $50$. Therefore, the answer will be the product of at least two different primes greater than $50$. The two smallest primes greater than $50$ are $53$ and $59$. Multiplying these two primes, we obtain the number $3127$, which is also the smallest number on the list of answer choices. So we are done, and the answer is $\boxed{\textbf{(A)}\ 3127}$.

One year, Mr James travels 8 x 10^3 miles for his job. The next year he traveled 1 x 10^4 miles. How many more miles did he travel the second year than he did the first year? Please give me the answer and explain ToT
Answer:
2 000 miles
Step-by-step explanation:
In the first year, Mr James travels 8 x [tex]10^{3}[/tex] miles = 8 000 miles.
The second year, he traveled 1 x [tex]10^{4}[/tex] miles = 10 000 miles.
Comparing the distance covered in the two years,
10 000 miles - 8 000 miles = 2 000 miles
Therefore, Mr James travels 2 000 more miles in the second year than he did the first year.
Let's assume that Mr James conveys himself to his place of work all through the first year in his private car. But in the second year, there were some days in which the car was not available. So he had to go for his job by public transportation. This itch during those days, could cause an increase in the distance covered from his home to his place of work for the second year.
How much of the circle is shaded? simply your answer
Answer:
The part that is shaded is 5/14
Step-by-step explanation:
The total circle is 1
1/2 + 1/7 + x = 1 where x is the shaded area
Multiply each side by 14 to get rid of the fractions
14(1/2 + 1/7 + x) = 1*14
7 + 2 + 14x = 14
9+14x = 14
Subtract 9 from each side
14x = 5
Divide by 14
x = 5/14
The part that is shaded is 5/14

Which expression has the same value as -18-(-9)?
0 - 18+2
-12-(-3)
- 1945
O-8-(-4)
Answer:
the answer is -12-(-3)
Step-by-step explanation:
The expression equivalent to -18-(-9) is -12-(-3)
What are expressions?An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation.
Given is an expression, -18-(-9), we are given to find the expression equivalent to it,
-18-(-9) = -18+9 = -9
1) -18+2 = -16 (not equivalent)
2) -12-(-3) = -12+3 = -9
Therefore, we see, the value of expressions -12-(-3) and -18-(-9) are equivalent,
Hence, the expression equivalent to -18-(-9) is -12-(-3)

find 3+root 2/3-root 2=a+b root2
Answer:
a = [tex]\frac{11}{7}[/tex] ; b = [tex]\frac{6}{7}[/tex]
Step-by-step explanation:
[tex]\frac{3 + \sqrt{2}}{3 - \sqrt{2} } = a + b\sqrt{2} \\\\[/tex]
Rationalising [tex]\frac{3 + \sqrt{2}}{3 - \sqrt{2} }[/tex] gives :-
[tex]\frac{3 + \sqrt{2}}{3 - \sqrt{2} } = \frac{(3 + \sqrt{2})(3 + \sqrt{2})}{(3 - \sqrt{2})(3 + \sqrt{2}) } = \frac{(3 + \sqrt{2})^2}{3^2 - (\sqrt{2})^2 } = \frac{11 +6\sqrt{2} }{7}[/tex]
Comparing [tex]\frac{11 + 6\sqrt{2} }{7}[/tex] with [tex]a + b\sqrt{2}[/tex] gives
a = [tex]\frac{11}{7}[/tex] & b = [tex]\frac{6}{7}[/tex]
Answer:
[tex]\frac{11}{7}[/tex] + [tex]\frac{6}{7}[/tex] [tex]\sqrt{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{3+\sqrt{2} }{3-\sqrt{2} }[/tex]
Multiply the numerator/ denominator by the conjugate of the denominator.
The conjugate of 3 - [tex]\sqrt{2}[/tex] is 3 + [tex]\sqrt{2}[/tex] , thus
= [tex]\frac{(3+\sqrt{2})(3+\sqrt{2}) }{(3-\sqrt{2})(3+\sqrt{2}) }[/tex] ← expand numerator/ denominator using FOIL
= [tex]\frac{9+6\sqrt{2}+2 }{9-2}[/tex]
= [tex]\frac{11+6\sqrt{2} }{7}[/tex]
= [tex]\frac{11}{7}[/tex] + [tex]\frac{6}{7}[/tex] [tex]\sqrt{2}[/tex] ← in the form a + b[tex]\sqrt{2}[/tex]
with a = [tex]\frac{11}{7}[/tex] and b = [tex]\frac{6}{7}[/tex]

The area of a sector is 30 m2 in a circle with radius 4 m. What is the arc length of the sector?
Answer:
15 m
Step-by-step explanation:
The area of the circle is
A =pi r^2
A = pi 4^2 = 16 pi
The area of the sector is 30
The fraction is
30/16 pi
Take this time 2pi which are the radians of a circle
30 /16 pi * 2 pi = 15/4
This is the number of radians the angle is
The arc length is s = r * theta where theta is in radians
s = r theta
= 4 * 15/4
= 15

Answer:

Step-by-step explanation:
6x + 2y = -10
y = -4x - 8
6x + 2(4x - 8) = -10
6x + 8x - 8 = -10
14x - 8 = 10
(we put together the like terms)
14x = 10 + 8
14x = 18
x = [tex]\frac{18}{14}[/tex]
x = 1.28571428571
