Step-by-step explanation:
-k + 4(k + 1) = 2k
-k + 4k + 4 = 2k
-k + 4k - 2k = -4
(-1 + 4 - 2)k = -4

Given set is A = {x:x+3 = 3 and x € N }
A is an empty set .
Reason :-
Put x = 1 then x+3 = 1+3 = 4
Put x = 2 then x+3 = 2+3 = 5
If we put x = 1,2,3...
We get { 4,5,6...}
So there is no natural number for x to get x+3 = 3
So ,There is no element to write for the set A
A is an empty set .
Note :-If x€W then x+3 = 0+3 = 3 then A is not an empty set .
Simplify the expression.
5+2⋅[(2+2)⋅5+5]
Answer:
55
Step-by-step explanation:
Remember PEMDAS
solve parentheses first : (2+2) = 4
Then multiply inside the brackets 4 x 5 = 20
20+5 = 25
Then multiply 2 x 25 = 50
50+5 = 55
Your answer would be 55

Determine which lines, if any, are parallel. Choices may be repeated and some might not be used at all. Question 6 options: m∠20 + m∠21 = 180° ∠13 ≅ ∠17 ∠4 ≅ ∠9 m∠14 + m∠17 = 180° ∠10 ≅ ∠23 ∠8 ≅ ∠19 1. a || b 2. b || c 3. a || c 4. d || e 5. doesn't prove lines parallel
Answer:
Step-by-step explanation:
The answers are shown below:
1. m∠20 + m∠21 = 180-----> a || b
2. ∠13 ≅ ∠17 -----> a || c
3. ∠4 ≅ ∠9-----> d || e
4. m∠14 + m∠17 = 180°------> a||c
5. ∠10 ≅ ∠23 ------> b||c
6. ∠8 ≅ ∠19 --------> d || e
What are parallel line?The fundamental characteristics listed below make it simple to recognise parallel lines.
Straight lines that are always the same distance away from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.m∠20 + m∠21 = 180-----> (Co - interior angle)
a || b
∠13 ≅ ∠17 -----> Corresponding angle
a || c
∠4 ≅ ∠9-----> alternate exterior angle
d || e
m∠14 + m∠17 = 180°------> (Co - interior angle)
a||c
∠10 ≅ ∠23 ------>alternate interior angle
b||c
∠8 ≅ ∠19 (Vertically opposite angle)
d || e

Find the products 1/ 5a^2b - 1/3c and -25ab - 1/6 cd
Answer:
find it yourself
Step-by-step explanation:
hahahhaha
The required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.
Given that,
To find the products [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd].
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Given expression,
= [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd]
= 1/5a²/b[-2/5ab - 1/6cd] - 1/3[-2/5ab - 1/6cd]
= -2/25a³b² - 1/60abcd +2/15ab + 1/18abcd
= -2/25a³b² + 2/15ab + 7/180abcd
Thus, the required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.

According to the table, what was the hiker’s total displacement?
A.0
B.6 km north
C.10 km northeast
D.20 km
Answer:
A: 0
Step-by-step explanation:
Important to remember - total displacement is the direct distance between the start and finish points, and isn't always equal to the total distance travelled.
In the case of the table above, the hiker travels the same distance in opposite directions, which actually means they cancel each other out! Traveling 4 km to the west, then 4 km to east means you end up in the same spot, right? So your total displacement is 0! (or 4 - 4, which equals 0). Same happens with the north-south hikes - the hiker ends up in the same spot, as the displacement is equal to 6 - 6 = 0.
So, the total displacement of the hiker is 0. (Even though the hiker travelled 20 km!)

Answer:

Step-by-step explanation:
3x-(2x-1)=7x-(3*5x)+(-x+24)
Answer:
[tex]\boxed{\boxed{\sf x=\frac{23}{10}}\: \sf or \:\boxed{x=2.3}}[/tex]
_________________
[tex]\boxed{\sf Step\: By\:Step:- }[/tex]
[tex]\sf 3x-\left(2x-1\right)=7x-\left(3\times \:5x\right)+\left(-x+24\right)[/tex]
Remove the parentheses:
[tex]\to\sf 3x-\left(2x-1\right)=7x-3\times \:5x-x+24[/tex]
Combine like terms:
[tex]\sf ^*7x-x=6x[/tex]
[tex]\to\sf 3x-\left(2x-1\right)=6x-3\times \:5x+24[/tex]
Multiply 3 and 5x = 15x:-
[tex]\to\sf 3x-\left(2x-1\right)=6x-15x+24[/tex]
Combine like terms:
[tex]\sf ^*6x-15x=-9x[/tex]
[tex]\to\sf 3x-\left(2x-1\right)=-9x+24[/tex]
Expand: 3x-(2x-1)= x+1
[tex]\to\sf x+1=-9x+24[/tex]
Subtract 1 from both sides:
[tex]\to\sf x+1-1=-9x+24-1[/tex]
[tex]\to\sf x=-9x+23[/tex]
Add 9x to both sides:
[tex]\to\sf x+9x=-9x+23+9x[/tex]

Divide both sides by 10:

Point DD is located at (-2,-6)(−2,−6) on the coordinate plane. Point DD is reflected over the x-axis to create point D'D. Point D'D
is then reflected over the y-axis to create point D''D
What ordered pair describes the location of D''?D
Answer:
(2,6)
Step-by-step explanation:
since DD is at (-2,6) and you're reflecting it just count 6 spaces from the point to the x-axis then go up 6 more the point will be at (-2,6) and if you go to the right 2 spaces to the y-axis then go two more you'll end up at (2,6)
