write x<19 in interval notation
The inequality x<19 is the unbounded interval
answer:____
Answers
The resulting inequality equation in interval form is (-∞, 19).
Interval form of an inequalityThe range of values that might result in an inequality being true can be represented using interval notation.
There are two kinds of intervals, called open and closed (explained below), and each has a unique manner to notate it so we can distinguish between the two.
Given the inequality expression x < 19. This means that the interval must contain values that are less than 19 (19 excluded.)
The inequality x<19 as an unbounded interval is given as (-∞, 19).

Thanks for the response.
i did the same for 2-square root 10, for 2 - 3.1 < 2 - sqrt 10 < 2 - 3.2 and thought 2 -3.1 < 2 -sqrt 10 < 2 -3.2,
-1.1<< 2 - sqrt 10 < -1.2 will be the answer but doesn't look like its right. Appreciate your help for this. thanks
Answers
Think of -1.1 as -11
Think of -1.2 as -12
I moved the decimal points to the right for each value
Then on a vertical number line, notice how -12 is below -11, so -12 < -11
If we divide both sides by 10, then we go from -12 < -11 to -1.2 < -1.1
In short, the final expression you have -1.1 < middleStuff < -1.2 is in the wrong order.
It should be -1.2 < 2 - sqrt(10) < -1.1
I swapped the places of -1.1 and -1.2
If you were to use a calculator, then 2-sqrt(10) = -1.162 approximately which fits the description of being between -1.2 and -1.1; this helps confirm we have the correct upper lower and upper bounds.
------------------------------------
Here's another way to look at it
3.1 < sqrt(10) < 3.2
-1*3.1 > -1*sqrt(10) > -1*3.2 ............ see note1 below
-3.1 > -sqrt(10) > -3.2
-3.1+2 > -sqrt(10)+2 > -3.2+2 ....... see note2
2-3.1 > 2-sqrt(10) > 2-3.2
-1.1 > 2 - sqrt(10) > -1.2
-1.2 < 2 - sqrt(10) < -1.1 ........... see note3
Footnotes
note1: For this step I multiplied all three sides by -1. Multiplying by a negative will flip the inequality signsnote2: I added 2 to all three sides. This does not flip any of the inequality signs.note3: We go from the form a > b > c to c < b < a. The outer sides 'a' and 'c' swap places while b in the middle stays where it is. The inequality signs flip. It might help to think of something like 3 > 2 > 1 flipping to 1 < 2 < 3.Which pair of similar triangles can be mapped from one to the other by dilation with scale 3 and center of dilation (0,0) followed by the translation (x,y) (x -6, y -6)

A bagel shop sold S plain bagels and 13 rye bagels. What is the ratio of the number of rye bagels to the number of plain bagels sold?
Answers
We can conclude that (B) 13 : 8 is the ratio of Rye bagels to Plain bagels.
What is the ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a bowl of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the total amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8. Ratios contrast two figures by ordinarily dividing them. A/B would be your formula if you were comparing one data point (A) to another data point (B).So, the ratio of Rye bagels to Plain bagels:
Rye bagels = 13Plain bagels = 8Then,
Rye bagels: Plain bagels13 : 8Therefore, (B) 13 : 8 is the ratio of Rye bagels to Plain bagels.

In order to calculate the function (f/g)(x), we need to divide f(x) by g(x).
First, let's find the zeros of the function f(x), so we can write it in the factored form:
[tex]\begin{gathered} f(x)=-10x^2+30x+40\\ \\ a=-10,b=30,c=40\\ \\ x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\ x=\frac{-30\pm\sqrt{900+1600}}{-20}\\ \\ x_1=\frac{-30+50}{-20}=-1\\ \\ x_2=\frac{-30-50}{-20}=4 \end{gathered}[/tex]So the factored form is:

A merchant bought several pieces of silk for $70. He sold all but two of them at a profit of $4 per piece. His total profit was $18. How many pieces did he originally purchase?
Let n be the number of pieces. He sold n - 2 pieces
Let p be the original price. His selling price = p + 4
Then n · p = 70.00
And (n - 2) · (p + 4) = 70.00+18.00 ---> np + 4n - 2p - 8 = 88.00
---> np + 4n - 2p = 96.00
---> 70.00 + 4n - 2p = 96.00
4n - 2p = 26.00
2n - p = 13.00
Trying some possibilities (7 & 1), (8 & 3), (9 & 5), and (10 & 7), finally gets us to the answer: n = 10 and p = 7.00.

To check for this, we have to get the slope of the two lines
The slope of a line can be calculated using the formula:

[tex]m\text{ = }\frac{0+1}{2-0}\text{ = }\frac{1}{2}[/tex]When two lines are perpendicular, the product of their slopes is equal to -1

A container has a capacity of 2/3 gallons. How many gallons are there in six of these containers in each container is filled to capacity.
Answers
The number of gallons in 6 containers is 4
How to determine the number of gallons?The statement is given as
A container has a capacity of 2/3 gallons
This means that
1 container = 2/3 gallons
Multiply both sides of the equation by 3/2
So, we have
3/2 * 1 container = 2/3 gallons * 3/2
Evaluate the products
So, we have
3/2 containers = 1 gallon
Multiply both sides by 4
So, we have
4 * 3/2 containers = 4 gallons

Range and Domain. The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

A function's domain and range are its constituent parts. In contrast to a function's range, which is the set of all potential outputs, a function's domain is the set of all possible inputs.
