Line segment CD is shown on a coordinate grid:
A coordinate plane is shown. Line segment CD has endpoints 1 comma 2 and 1 comma negative 1.
The line segment is reflected about the y-axis to form C′D′. Which statement describes C′D′?
C′D′ is perpendicular to CD.
C′D′ is half the length of CD.
C′D′ is greater than twice the length of CD.
C′D′ and CD are equal in length.
Answers
Answer:
im pretty sure the answer would be C'D' and CD would be equal in length!
Step-by-step explanation:
because you are only reflecting it across the y-axis, no changes will be made to the line itself, only the location of the line :)

Jolon used the slope-intercept form to write the equation of a line with slope 3 that passes through the point (5, –2). His work is shown below.
Step 1: Negative 2 = 3 (5) + b
Step 2: negative 2 = 15 + b
Step 3: Negative 2 + 15 = 15 + 15 + b
Step 4: Negative 13 = b
Step 5: y = 3x – 13
Analyze the steps. In which step did the Jolon make an error?
Answers
Answer:
step 3
Step-by-step explanation:
He should have subtracted 15 instead off adding 15. this would have gotten rid of the fifteen on the right side and left him with -17=b. Instead, he would have added 15 and gotten 13=30+b. That threw off the rest of the equation. The rest of the equation is wrong. b should equal -17
the slope-intercept equations should be y=3x-17

3 liters of water are shared equally by 5 people how much water does each person get? division equation to represent the situation
Answers
600 mililiters each
Step-by-step explanation:
1 liter is equal to 1000 mililiter and is multiplied by 3 and the answer is devided into 5.
The division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.
What is division?The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.
Now it is given that,
Number of People = 5
Liters of water = 3
So, Water shared by each person = Liters of water / Number of People
⇒ Water shared by each person = 3/5
This is the division equation to represent the situation.
⇒ Water shared by each person = 0.6
Thus, the division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.

The value of d in the given expression is 2/5.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given an expression as
3/2 = 5d - 1/2
we need to solve for d;
3/2 = 5d - 1/2
5d = 3/2 + 1/2
5d = 4/2
5d = 2
d = 2/5
Hence, the value of d in the given expression is 2/5.

Answer:
-Why is Democritus important with regard to atomic theory? Democritus developed his atomic philosophy as a middle ground between two opposing Greek theories about reality and the illusion of change. He argued that matter was subdivided into indivisible and immutable particles that created the appearance of change when they joined and separated from others.
-Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
-What subatomic particle did JJ Thomson discover? He discovered the electron in 1897.
-In 1913, Neils Bohr proposed a new atomic model known as the Bohr's model, which is patterned after the solar system.
- List the principles of Bohr's model:
a. An electron moves around the nucleus in a circular orbit.
b. An electron's angular momentum in the orbit is quantisized.
c. The change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon.
- In 1926, Erwin Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This model is known as the Rutherford Model of an atom.
-In 1932, James Chadwick discovered the neutron.
-Since 1932, the atomic theory has been further enhanced by the concepts that protons and neutrons are made of even smaller units called quarks. The quarks themselves are in turn made of vibrating strings of energy.
-Everything in the universe (except energy) is made up of matter.
-Therefore everything in the universe is made up of atoms.
-An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons and electrons.
The protons and the neutrons make up the centre called the nucleus.
The electrons fly around above the nucleus in a small cloud.
The electrons carry a negative charge and the protons carry a positive charge.
In a normal (neutral) atom the number of protons is the same number of electrons.

Conversion a mixed number 2 2/5 to a improper fraction:-
=> 2 2/5 = 2 × 5 + 2 = 12/5
To find new numerator:
a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/5
= 10/5
b) Add the answer from previous step 10 to the numerator 2. New numerator is 10 + 2 = 12
c) Write a previous answer (new numerator 12) over the denominator 5.
Two and two fifths is twelve fifth
Multiple:
= 12/5 × 5/7
= 12 × 5/5 × 7
= 60/35
= 12 × 5/7 × 5
= 12/7
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(60, 35) = 5. In the next intermediate step, , cancel by a common factor of 5 gives 12/7
12/7 in mixed fraction is 1 5/7

Step-by-step explanation:
Equivalent Fractions with the LCD
8/21 = 8/21
2/7 = 6/21
Solution:
Rewriting input as fractions if necessary:
8/21, 2/7
For the denominators (21, 7) the least common multiple (LCM) is 21.
LCM(21, 7)
Therefore, the least common denominator (LCD) is 21.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
8/21 = 8/21 × 1/1 = 8/21
2/7 = 2/7 × 3/3 = 6/21
