one angle of linear pair is 4 time the other find the angles
need answer asap
Answer: The angles are 36 and 144.
Step-by-step explanation:
Let the linear pairs be 4x and x
so
4x + x = 180 (being linear pair)
or, 5x = 180
or, x = 180/5
so, x = 36
so, 4x = 4*36 = 144

Which function is the same as the linear function represented by the table ?
Answer:
A) y = 3x – 2
Step-by-step explanation:
Just check the results: when you put the numbers of the x-colum from the table, the result will be the corresponding numbers of the y-colum. and that means this is the right equation
Mike weights 200 pounds and plans to lose 1.5 pounds a week. Jeff weights 180 pounds and plans to lose 0.5 pounds a week. When mike and Jeff weigh the same?
Answer:
20 weeks
Step-by-step explanation:
200-1.5w=180-0.5w
You can double-check by substituting 20 for w (weeks), if it is equal, then the equation is correct.

The perimeter of a triangle is 16x−6. If two sides measure 3x+2 and 4x−9, then how long is the third side?
Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,
we know,
[tex] \hookrightarrow \: y + 3x + 2 + 4x - 9 = 16x - 6[/tex]
[tex] \hookrightarrow \: y + 7x - 7 = 16x - 6[/tex]
[tex] \hookrightarrow \: y = 16x - 6 - 7x + 7[/tex]
[tex] \hookrightarrow \: y = 6x + 1[/tex]
hence, measure of the third side is 6x + 1

Hi! I'm happy to help!
First, we need to get our two equations, so we need to look at what facts we have throughout the equation. It tells us that x is 3 times as much as y. We can use this to write our first equation:
3y=x
All of the interior angles inside of a triangle add up to 180°, and because we already have 3 angles, we can use this information to make our second equation:
x+y+45=180
Now, we have to use these equations together to get our answer.
Since we can replace 3y for x (first equation) we can replace it in our second equation:
3y+y+45=180
We edit both sides of the equation in the same way to get the same outcome, but to simplify. Since we are solving for y, let's isolate it by subtracting 45 from both sides:
3y+y+45=180
-45 -45
3y+y=135
Let's combine the 3y and y to make things simpler:
4y=135
From here, we divide both sides by 4, to isolate y:
y=33.75
Now that we have our y value, we can use our first equation to solve for x:
3y=x
3(33.75)=x
101.25=x
We used our equations to get both our x and y values: 33.75, and 101.25.

Is the set of real numbers closed under addition? Explain why or why not. If it is not closed, give an example
Answer: Yes, the set of real numbers is closed under addition.
Explanation:
Let x and y be two real numbers. Their sum x+y is some other real number. This is what it means when we say the set of real numbers is closed under addition. Taking any two numbers and adding them will get us some other real number.
There is no way to have x+y be nonreal while x,y are both real.
Kareem is putting 8 books in a row on his bookshelf. He will put one of the books, Pride and Prejudice, in the first spot. He will put another of the books, Little Women, in the last spot. In how many ways can he put the books on the shelf
Answer:
720
Step-by-step explanation:
He has 8 books. He knows the placement of 2... so
8 - 2 = 6
To find the total... 6!
6*5*4*3*2*1 = 720
The required number of the ways the book is arranged on the shelf is 720 ways.
Given that,
Kareem is putting 8 books in a row on his bookshelf. He will put one of the books, Pride, and Prejudice, in the first spot. He will put another of the books, Little Women, in the last spot. In how many ways can he put the books on the shelf is to be determined.
In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
here,
There are 8 books to be arranged, 1st and last place is fixed,
now remaining books = 8 - 2 = 6
now, a number of combinations can be formed with the number 6,
= 6!
= 6×5×4×3×2×1
= 720
Thus, the required number of the ways the book is arranged on the shelf is 720 ways.

Many doctors rely on the use of intravenous medication administration in order to achieve an immediate response of a particular drug's effects. The concentration, C, in mg/L, of a particular medication after being injected into a patient can be given by the function C of t is equal to the quantity negative 10 times t squared plus 50 times t end quantity over the quantity t squared plus 4 times t plus 3 end quantity comma where the time, t, is hours after injection. Part A: What is the domain of the function C(t) based on the context of the problem? Show all necessary calculations. (5 points) Part B: Graph the function to determine the greatest concentration of the medication that a patient will have in their body. (5 points)
Graphs are used to show the relationship between variables, where the variables are represented by a pair of axes.
The domain of the function is [tex]t \ge 0[/tex] The greatest concentration of the medication is 5mg/LGiven that:
[tex]C(t) = \frac{-10t^2 + 50t}{t^2 + 4t + 3 }[/tex]
(a): The domain of the function
Because the medication concentration C(t) is a function of time (t), the domain is the possible values t can take.
t, cannot take negative values (i.e. it is not possible to have a negative time).
The least possible value of t is 0
So, the domain of the function based on the context is:
[tex]t \ge 0[/tex]
(b) The greatest concentration of the medication
From the graph (see attachment), the maximum y-value is 5.
Hence, the greatest concentration of the medication is 5 mg/L
