What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.We have Trinity who has 48.75 inches of ribbon. She cut the ribbon into 15 equal-sized pieces.
Assume that the length of each piece be [x]. Then, we can write -
15x = 48.75
x = 48.75/15
x = 3.25 inches
Therefore, the length of each piece be 3.25 inches.

A line passes through the points (-2,-4) and (3, 5). Which equation best represents a line
parallel to this line?
A) y = -5/9x+ 4
B) y = 9/5x + 4
C) y = 1x + 4
D) y = -4/3x + 4
Answers
m=(y2-y1)/(x2-x1)
m=(5-(-4))/(3-(-2))
m=9/5
so the answer is B since the gradient also 9/5
The equation best represents a line parallel to the given line is y = 9/5x - 2/15.
What is the equation of line?The general equation of a straight line is
y = mx + c,
where m is the gradient, and y = c is the value where the line cuts the y-axis.
This number c is called the intercept on the y-axis.
Now it is given that the line passes through (-2,-4) and (3,5).
So here,
x1 = -2;
y1 = -4;
x2 = 3;
y2 = 5
Hence slope of the line is given as,
m1 = (y2 - y1)/(x2 - x1)
⇒ m1 = {5-(-4)}/{3-(-2)}
⇒ m1 = (5+4)/(3+2)
⇒ m1 = 9/5
Since both the lines are parallel, hence
m1 = m2 = 9/5
Therefore equation of line parallel to the given line will be,
(y - y1) = m2( x - x1)
⇒ {y-(-4)} = 9/5{x - (-2)}
⇒ y + 4 = 9/5(x +2)
⇒ y + 4 = 9/5x + 18/5
⇒ y = 9/5x + 18/5 - 4
⇒ y = 9/5x - 2/15
Hence, The equation best represents a line parallel to the given line is y = 9/5x - 2/15.

9/10 - (1/8-3/10)= please help me through steps
Answers
Answer:
43/40 or 1 3/40
Step-by-step explanation:
9/10 - (1/8 - 3/10)
Remember, we have to solve what's in the parentheses first!
To find 1/8 - 3/10, we must find the least common multiple of the denominators, which is 8 and 10.
Let's list the multiples of 8 and 10
Multiples of 8: 8, 16, 24, 32, 40, 48, 56...
Multiples of 10: 10, 20, 30, 40, 50, 60...
We found a match! 40 is a multiple of both 8 and 10, so we can use that.
To make the denominator 40 for 1/8, we have to multiply both the numerator and denominator by the same number, and the denominator must equal 40 after.
So,
8 times what equals 40?
To make it easier, we can do 40 / 8, which is 5.
That means we multiply the denominator and numerator by 5, so we get 5/40 - 3/10.
If you do the same thing for 3/10, you get 12/40.
Our equation is much easier!
We can easily do 5/40 - 12/40, which is -7/40.
Now, we do 9/10 - (-7/40)
Remember, two minuses right next to each other make a plus!
Our equation is now 9/10 + 7/40.
If you do the least common multiple for 9/10, you get 36/40.
Finally, we do 36/40 + 7/40, which is 43/40.
If it's asking for a mixed number, it would be 1 3/40.
Therefore, 9/10 - (1/8 - 3/10) equals 43/40 or 1 3/40!

What is the solution to m(n(x))? m(x)=10x−9 n(x)=7x2+4
Answers
The composite function m(n(x)) is 70x²+ 19
Given the functions
m(x)=10x−9
n(x)=7x²+4
We need to get the composite function m(n(x))
m(n(x)) = m(7x²+4)
To get m(7x²+4), we need to replace x as 7x²+4 in function m(x) as shown:
m(7x²+4) = 10(7x²+4) - 9
m(7x²+4) = 70x²+ 28 - 9
m(7x²+4) = 70x²+ 19
Hence the composite function m(n(x)) is 70x²+ 19

You are recently promoted as the chief traffic management officer of a major city in the country. Based on recent data, you learned that one of the leading causes of road accidents is overspeeding.
In your desire to minimize road accidents, you went out to observe how traffic management rules are implemented on the streets. Your attention was caught by a fast-moving car that seemed to be breaking the speed limit of 100 kilometers per hour(km/hr.), and so you followed it along the highway. After a short time, the driver of the car noticed you and started to slow down. Eventually, he stopped on the side of the road.
Supposed the speed of the car had been noted during this time and is modeled by the quadratic equation y = 3x² + 17x - 20, where y represents the speed of the car in km/hr. and x represents the number of minutes after you started following the car. How long did it take for the car to be under surveillance before it could finally stop on the side of the road? Did the driver of the car really break the speed limit of 100 km/hr.? Explain.
You will prepare an observation report highlighting whether it is necessary to come up with more stringent implementation of traffic rules based on the outcome of your analysis of the problem that you encountered on the road.

By what least number should 4851 be divided to get a perfect square number ? Also find the square root of the square number so obtained ?
Answers
Answer:
The least number should 4851 be divided to get a perfect square number = 11
The square root of the obtained perfect square number is 21
Step-by-step explanation:
Given number = 4851
It can be written as
4851 = 3×1617
4851 = 3×3×539
4851 = 3×3×7×77
4851 = 3×3×7×7×11
4851 = (3×3)×(7×7)×11
It is clear that We should divide the given number by 11 then we get a perfect square number.
4851/11 = 441
441 = 21×21
=> 441 = 21²
=> √441 = √(21²)
=> √441 = 21
Answer:-The least number should 4851 be divided to get a perfect square number = 11
The square root of the obtained perfect square number is 21
Used Method :-→ Prime Factorization Method
Answer:
11 is the least number and the when you take the square root of the number you get 21
Step-by-step explanation:
The easiest way to solve this problem is guess and check.
First of all, a perfect square NEEDS to be a WHOLE number
Since 4851 is odd, you cannot divide it by an even number evenly, as it would result in a number with a remainder or leftover decimal amount.
This means you cannot divide by 2, 4,8...etc
We just have to guess and check odd numbers starting at 3.
4581/ 3 = 1527 sqrt(1527) = 39.07684737 decimal so not this one
4581/ 5 = 916.2 decimal so not this one
4581/ 7 = 654.4285714 decimal so not this one
4581/ 9 = 509 sqrt(509) = 22.56102835 decimal so not this one
4581/ 11 = 441 sqrt(441) = 21
This is the first instance where 4581 is divisible by a number that yields a perfect square, so 11 is the least number and the square root of the result is 21.

30/100 caffeine
Of the 65/100, 22 are caffeine free but that is unnecessary info for the question. The 22 caffeine free would fall under the 65/100 anyways.
So 65 + 30 = 95
100-95 = 5
5/100 simplified is 1/20
Yes, you are correct . Since we know 65 sodas are diet and 30 are caffeine-free.
65 + 30 = 95
What plus 95 equals 100?
95 + x = 100
Or 100 - 95 = 5
= 5/100
When 5/100 is simplified, it equals 1/20.

Step-by-step explanation:

I hope I could help. Enjoy your day! Maybe brainiest if this was right?
No pressure! :)
Answer:
37
Step-by-step explanation:
This is a vertical angle, meaning 74 and 2x would be equivalent to each other. So we have to make 2x equal to 74. We set up an equation, 2x = 74. Divide 2 for both sides; 74 divided by 2 = 37; 2x divided by 2 (2 cancels out, leaving x alone). Therefore, x = 37.
To check, substitute x with 37. 37 times 2 is 74, and since the left is 74 the right also have to be 74.

Step-by-step explanation:
Given that ∠DOE is 51 degrees we know that ∠AOE is 180 degrees as it is a straight line.
∠BOD is a right angle given the ∟symbol so therefore ∠BOD is equal to 90 degrees.
m∠DOE + m∠BOD = 141 degrees (because 51 + 90)
Therefore m∠AOB = 39 because 180 - 141 = 39
Straight angles are equal to 180! Hope this helped
