Step-by-step explanation:
a restricting is only necessary, if we need to limit the x values or the y values for various reasons.
the limit for the x values are to eliminate any values that would create an invalid or otherwise undefined result.
otherwise the inequality itself establishes a restriction already.
e.g. sqrt(x) + 3 >= 1 would need an additional restriction
x >= 0 to know we can't even try small negative x to find out verify the solution.
something like
sqrt(x² + 3) >= 1 does not need any further restrictions, because we can use any value for x, from - infinity to +infinity. and the inequality will always be valid.
also consider, that the left side can never get smaller than sqrt(3) which is larger than 1. so, really everything goes.
we could say something like
sqrt(x² + 16) >= 5
we still don't need to give any additional restrictions, but the inequality itself rules out all x that are
-3 < x < 3.
Solve for x
3x = 4y

When traveling to Great Britain, Bethany exchanged $635 US dollars into £580 British pounds. How many pounds did she receive for each US dollar?
After the exchange from the U.S dollar to British pounds, Bethany received £0.91 for each U.S. dollar.
What is an exchange rate?An exchange rate is a rate or a price of one country's currency in terms of another.
The exchange rate describes how much each currency can be obtained when converting one currency to another.
In this instance, the exchange rate between the U.S. dollar and the British pound is $1 = £0.91.
Data and Calculations:Total US dollars with Bethany = $635
The total British pounds received by Bethany after the exchange = £580
Exchange rate per U.S. dollar = £0.91 (£580/$635)
Exchange rate per British pound = $1.095 ($635/£580)
Thus, Bethany received £0.91 for each U.S. dollar.

twenty more than a number is less than twice the same number
Answer:
x+20<2x
Step-by-step explanation:
20 more than a number implies that twenty must be added to the variable. Then, because it says less than you add a less than symbol. Finally, twice the same number tells you to use x again but since it’s being multiplied by 2, typing 2x makes it easier to understand.

Step-by-step explanation:
Given a graph of an original object and its image after dilation, you want to know the scale factor of the dilation.
DilationThe scale factor multiplies each of the coordinates.
The original coordinates of point A are (0, 1).
The coordinates of dilated point A' are (0, 2).

What is the 99th digit of pie?
The approximation of pi to 99 decimal places is 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679.
We have,
Determining the 99th digit of pi requires an understanding of the properties of pi and how it is calculated.
Pi is an irrational number, which means it has an infinite number of non-repeating decimal digits.
Since pi has an infinite number of digits, it is not possible to directly state the 99th digit without extensive computation.
However, various methods and algorithms have been developed to approximate the value of pi to a specific number of decimal places.
The 99th digit of pi has not been explicitly determined.
Thus,
The approximation of pi to 99 decimal places is 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679.

Step-by-step explanation:
it cant be a or c because if it is a negative then there is no need to put a + sign or add another - sign
Answer:
A
Step-by-step explanation:
Let's get the answer.
Suppose the question was the distance between 12 and 1. You would write it as 12 - 1 = 11. So you have to pick an answer that looks like this example.
B: is actually 11 12 -1 = 11
C: is 12 +(-1) = 12 - 1 which also gives 11
D: -1 -12 = -13. You are not really really with a distance here. You are combining 2 negative numbers.
So the answer is A.
-12 - (-1) = -12 + 1 = - 11

What is a right angle?A right angle can be defined as a type of angle that is formed by the intersection of two (2) straight lines at 90 degrees. This ultimately implies that, a right angle has a measure of 90 degrees.
How to calculate the magnitude of cos θ?In order to determine the magnitude of cos θ, we would apply the law of cosine because the given side lengths represent the adjacent side and hypotenuse of a right-angled triangle.
cos(θ) = Adj/Hyp
Where:
Adj represents the adjacent side of a right-angled triangle.Hyp represents the hypotenuse of a right-angled triangle.θ represents the angle.Substituting the parameters into the formula, we have;

Special Angle Pairs
Find m<1
Please help !
Special Angle Pairs, m<1, then the expression is,
(4x + 16)° = (2x + 34)° = 52° where, x = 9°
⇒ As shown in Graph,
⇒ (4x + 16)° is congruent to (2x + 34)°
⇒ Because they are vertical angles.
The angles opposite each other when two lines cross. They are always equal. In this example a° and b° are vertical angles. "Vertical" refers to the vertex (where they cross), NOT up/down.
These are vertical angles.
So,
We can write,
(4x + 16)° = (2x + 34)°
Calculate the equation,
(4x - 2x)° = (34 - 16)°
We can use sum or difference,
(2x)° = (18)°
We can divide the values,
(x)° = (18/2)°
x° = 9°
Hence,
x° = 9°
We can substitute x = 9° value in (4x + 16)° and (2x + 34)° expression,
So,
We can use,
= (4x + 16)°
= (4*9 + 16)°
= (36 + 16)°
= 52°
Therefore,
(4x + 16)° = 52°
We can use,
= (2x + 34)°
= (2*9 + 34)°
= (18 + 34)°
= 52°
Therefore,
(2x + 34)° = 52°
Hence,
Special Angle Pairs, m<1, then the expression is,
(4x + 16)° = (2x + 34)° = 52° where, x = 9°

Diseases tend to spread according to the exponential growth model. In the early days of AIDS, the growth multiplier (i.e. common ratio) was around 2.0. In 1983, about 1800 people in the U.S. died of AIDS. We can use the exponential model:
P
n
=
1800
(
2.0
n
)
.
If the trend had continued unchecked, how many people would have died from AIDS in 2004?
If the trend had continued unchecked, 3,774,873,600 people would have died from AIDS in 2004
How many people would have died from AIDS in 2004?The equation of the function is given as
P(n) = 1800(2.0)^n
Where n represents the number of years since 1983
There are 21 years from 1983 to 2004
This is calculated as
n = 2004 - 1983
n = 21
Substitute 21 for n in the equation P(n) = 1800(2.0)^n
So, we have
P(21) = 1800(2.0)^21
Evaluate
P(21) = 3774873600
Hence, if the trend had continued unchecked, 3,774,873,600 people would have died from AIDS in 2004

On the attached line segment, we have the following points assuming that the point A is at A = 0
So, we have

The above means that
AB : CB = C - A : B - C
