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
Answers
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)

a 10kg box putting pushed with a force of 24 Newtons and a fraction of 12N. Determine coefficient of Friction and Determine acceleration of the Box
PLEASE HELP
Answers
Assuming the force is applied horizontally over a flat surface, the net horizontal force is
F (h) = 24 N - 12 N = (10 kg) a
Solve for the acceleration a :
12 N = (10 kg) a
a = 1.2 m/s²
Meanwhile, the net vertical force is zero since the box of only moving horizontally.
F (v) = n - (10 kg) g = 0
where n is the magnitude of the normal force exerted upward by the surface. We see that
n = (10 kg) (9.8 m/s²)
n = 98 N
The friction force has a magnitude that is proportional to the normal force,
12 N = μ (98 N)
where μ is the coefficient of kinetic friction. Solve for μ :
μ = (12 N)/(98 N)
μ ≈ 0.12

65−2x=6x+9
x2+1=8x−5
3+4x=5x−4
9−x=14x
Answers
Step-by-step explanation:
x = 7
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
Option C
The equations having the solutions 7 are 65−2x=6x+9 and 3+4x=5x−4. the correct options are A and C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that we have to check all the equations having solution 7.
Checking option A,
65−2x=6x+9
65 - ( 2 x 7 ) = ( 6 x 7 ) + 9
51 = 51
Checking option B,
x²+1=8x−5
(7²) + 1 = ( 8 x 7 ) - 5
50≠ 51
Checking option C,
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
Checking option D,
9 - x = 14x
9 - 7 = 14 x 7
2≠ 98
Therefore, the equations having the solutions 7 are 65−2x=6x+9 and 3+4x=5x−4. the correct options are A and C.

Given f(x)=3x−3 and g(x)=2x−3
f(3)−g(5)+12=
Answers
Answer:
When f(x) = 3x - 3 and g(x) = 2x - 3,
f(3) - g(5) + 12 = 11.
Step-by-step explanation:
Given:
f(x) = 3x - 3
g(x) = 2x - 3
First solve f(3).
f(x) = 3x - 3
Substitute input value.
f(3) = 3(3) - 3
Multiply 3 and 3.
f(3) = 9 - 3
Subtract 3 from 9.
f(3) = 6
Next, solve g(5).
g(x) = 2x - 3
Substitute input value.
g(5) = 2(5) - 3
Multiply 2 and 5.
g(5) = 10 - 3
Subtract 3 from 10.
g(5) = 7
Knowing these values, solve the expression.
f(3) - g(5) + 12
Replace functions with their values.
6 - 7 + 12
Subtract 7 from 6.

Add -1 and 12.

Answers
Answer:
From construction, we construct point M as the center of the figure. According to the linear pair postulate, we know that the sum of the angles on a straight line equal to 180 degrees. Therefore, we know that the other angles have to be 90 degrees. Therefore the angles are congruent because all right angles are congruent.

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have given few Resultant value.
So, x = 5 shows that the resultant value of x is 5.
and, x = 0 shows that the resultant value of x is 0.
and, 5 = 5 shows only equality and for equation there must be variable.

Since 12 is a multiple of 3, we can multiply the 3 by 4. Now what you do to the denominator you must do to the Numerator. 1 x 4 = 4

If 2a - b = 4 , find a.
Answers
To solve for 'a' we have to make it the subject of the equation. Since there are two unknowns ('a' & 'b'), we won't get a numerical value of 'a', but an expression in terms of the second unknown 'b'.
Since 2a - b = 4 [add 'b' to both sides]
then 2a = 4 + b [divide both sides by 2 = multiplying by ¹/₂]
a = ¹/₂ (4 + b)
