Answer:
Vertical Angles!
Step-by-step explanation:
Very simple!
Vertical angles are a pair of angles that are equal in degree measure.
Essentially, they are equal to each other. Nothing more to it.
This means that [tex]29=2x+3[/tex]!
I presume you have done math before, so this solves to be: [tex]x=13[/tex]
(I don't have a degree sign, but it should be there in your answer.)
Hope this helps!
P.S. How's life?

Let R be a relation on a collection of sets defined as follows,
R={(A,B)|A⊆B}
Then pick out the correct statement(s).
1) R is reflexive and transitive
2) R is symmetric
3) R is antisymmetric.
4) R is reflexive but not transitive
Answer:
Options 1) and 3) are correct.
Step-by-step explanation:
R={(A,B)|A⊆B}
Reflexive:
As A⊆A, [tex](A,A)[/tex]∈ R.
So, R is reflexive
Symmetric:
Let [tex](A,B)[/tex]∈ R. So, A⊆B
Take [tex]A=\{1,2\}\,,\,B=\{1,2,3,4\}[/tex]
Here, A⊆B but B⊄A
So, [tex](B,A)[/tex]∉ R
R is not symmetric
Transitive:
Let [tex](A,B)[/tex]∈ R and [tex](B,C)[/tex]∈ R
So, A⊆B and B⊆C.
Therefore, A⊆C
So,
[tex](A,C)[/tex]∈ R
Hence, R is transitive.
Option 1) is correct.
Antisymmetric:
Let (A,B)∈R and (B,A)∈R
So, A⊆B and B⊆A
Hence, A = B
So, R is antisymmetric
Option 3) is also correct.

If KL NM and KN ≈ KM, find NM and mMKN.
A. NM = 6; mK=70°
B. NM = 9; mK=35°
C. NM = 12; mK=55
D. NM = 12; mK=70
Answer:
D. NM=12; mK=70°
Step-by-step explanation:
KN≈KM so they have the same 55° and then
180°-55°-55°=70° and

The jewelry store had a watch sale for Father’s Day. The watch I want is priced $75 but is on sale for 40% off what, is the sale price of the watch?
Answer:
$45
Step-by-step explanation:
The watch was sold on sale of 40%. This means that the price of the watch on sale is 60% of the original price. (100%-40%=60%)
So, you find the 60% of the original price, $75.
75*0.6=45

x
3.5x = 60
x = $17.14
Answer:
Sarah multiplied the denominator by the denominator and the numerator by the numerator instead of finding the cross products. The equation should be 5x = 42, so the cost should be $8.40.

The graph shows a function that models the value V (in millions of dollars) of a stock portfolio as a function of time t (in months) over a 18-month period.
Answer:
Option (A)
Step-by-step explanation:
Graph attached shows a function that models the value V of a stock portfolio as a function of time.
y-values on the graph shows the value of V and x-values represent the time.
Lowest point of the curve shows the minimum value of V and highest point of the curve shows the maximum value.
Maximum value of the function → 6.93 at t = 4
Minimum value of the function → 1.05 at t = 15
Therefore, Option (A) will be the answer.
A number is doubled and then the product is increased by 6. This sum is then multiplied by -3, and the result is 54 greater than three times the opposite of the number. What is the number? *
Answer:
-24Step-by-step explanation:
Let the number be x
Then we have the equation
(2x + 6)*(-3) = -3x + 54 -6x - 18 = -3x + 546x - 3x = -18 - 543x = -72x = -72/3x = - 24let the number be "x" .
now according to the given question ;
(2x+6)×(-3)=-3x +54 -6x -18 = -3x + 54 6x - 3x = -18-543x = -72x = -72/3x = -24 The required answer is -24 .Can -0.05 be a probability?

so, my teacher barley taught us this yesterday and i'm still having trouble with some questions, could anyone please help? ( this is 7th grade math )
5.) x>20
11.)x≤−15
13.)x≥−21
2.)x≤−7
6.)x≤−45
10.)x≤10
12.)x≥−12
16.)x≤−4
Answer:
2. x ≤ -7
5. x > 36
6. x ≤ -40
10. x ≤ 10
11. x ≤ -15
12. x ≥ -12
13. x ≥ -21
16. x ≤ -4
Step-by-step explanation:
2. x ≤ -7 (You want to add 8 to both sides like any equation, but don't forget it is an inequality, not an equation!)
5. x > 36 (You need to multiply by 2, to get rid of the division. So multiply both sides by 2, that gets rid of the 2 on the one side, and you get 36 on the other side when you multiply 18 by 2).
6. x ≤ -40 (You need to multiply by -5. REMEMBER: When you multiply or divide by a negative, you switch the sign. So if it is a < then it would be a > and same with if you had ≤ then it would be ≥ instead).
10. x ≤ 10 (You need to divide by -2. And once again you switch the signs).
11. x ≤ -15 (Add 8, like you did in number 2).
12. x ≥ -12 (Multiply by 6. REMEMBER: Do NOT switch the signs if you the number you are dividing by is in the numerator, or if you multiply and the negative number is first, UNLESS you have 2 negatives.
13. x ≥ -21 (Multiply by 7).
16. x ≤ -4 (Divide by 10).

Which equation is an identity? O 3(x - 1) = x + 2(x + 1) + 1 O x-4(x + 1) = -3(x + 1) +1 O 2x + 3 = 1 = 1 (4x + 2) + 2 01 1 (6x – 3) = 3(x + 1) - x-2
HURRY!!!!
Answer:
Step-by-step explanation: C. 2x+3=1/2(4x+2)+2 hopes this helps:)
The equations that are identities are option B x – 4(x + 1) = –3(x + 1) + 1 and option C 2x + 3 = 1/2(4x + 2) + 2.
To check which equation is an identity, we need to simplify each equation and see if it is true for all values of x.
A. 3(x – 1) = x + 2(x + 1) + 1
Expanding the right side:
3(x – 1) = x + 2x + 2 + 1
3x – 3 = 3x + 3-3 = 3
This is a contradiction and cannot be true for any value of x. Therefore, option A is not an identity.
B. x – 4(x + 1) = –3(x + 1) + 1
Expanding both sides:
x – 4x – 4 = –3x – 3 + 1
-3x – 3 = -3x – 3
This equation simplifies to -3x - 3 = -3x - 3, which is true for all values of x. Therefore, option B is an identity.
Similarly,
Option C is an identity.
Option D is not an identity.

What is the image point of (1,0)(1,0) after a translation right 1 unit and up 4 units?
Answer:
0,4
Step-by-step explanation:
Each time a machine is repaired, it remains up for an exponentially distributed time with mean 5 hours. When it fails, its failure will be a type 1 failure with probability 0.7 and a type 2 failure with probability 0.3. Type 1 failures take an exponential amount of time with mean 1 hour to repair. Type 2 failures take an exponential amount of time with mean 1.25 hours. The status of the machine can be monitored as a continuous-time Markov chain with states 0 (= working), 1 (= repairing a type 1 failure), 2 (= repairing a type 2 failure). The parameters for the continuous-time Markov chain are:______
How do you these two questions?
Answer:
a) A = 3π/16
b) A = ∑₂°° (π/n⁴) = π⁵/90 − π
Step-by-step explanation:
(a) The area between the curve and the x-axis is:
A = ∫ₐᵇ y (dx/dt) dt
x = ½ (1 − cos t) cos t
dx/dt = ½ (1 − cos t) (-sin t) + ½ sin t cos t
dx/dt = -½ sin t + ½ cos t sin t + ½ sin t cos t
dx/dt = -½ sin t + sin t cos t
dx/dt = -½ sin t (1 − 2 cos t)
y dx/dt = -½ sin t (1 − 2 cos t) × ½ (1 − cos t) sin t
y dx/dt = -¼ sin²t (1 − 3 cos t + 2 cos²t)
y dx/dt = -¼ sin²t + ¾ sin²t cos t − ½ sin²t cos²t
y dx/dt = ⅛ (-2 sin²t) + ¾ sin²t cos t − ½ (sin t cos t)²
y dx/dt = ⅛ (-1 + 1 − 2 sin²t) + ¾ sin²t cos t − ½ (½ sin(2t))²
y dx/dt = ⅛ (-1 + cos(2t)) + ¾ sin²t cos t − ⅛ sin²(2t)
y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ (-2 sin²(2t))
y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ (-1 + 1 − 2 sin²(2t))
y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ (-1 + cos(4t))
y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t − ¹/₁₆ + ¹/₁₆ cos(4t)
y dx/dt = -³/₁₆ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ cos(4t)
A = ∫₀ᵖⁱ [-³/₁₆ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ cos(4t)] dt
A = -³/₁₆ t + ¹/₁₆ sin(2t) + ¼ sin³t + ¹/₆₄ sin(4t) |₀ᵖⁱ
A = [-³/₁₆ π + ¹/₁₆ sin(2π) + ¼ sin³π + ¹/₆₄ sin(4π)] − [0 + ¹/₁₆ sin(0) + ¼ sin³0 + ¹/₆₄ sin(0)]
A = -³/₁₆ π
We got a negative answer because the graph traces to the left (x decreases as t increases). So the area is simply ³/₁₆ π.
b) Each circle has radius 1/n², so the area is π (1/n)² = π/n⁴.
The sum of the areas from n=2 to n=∞ is:
A = ∑₂°° (π/n⁴)
A = ∑₁°° (π/n⁴) − π
A = π ∑₁°° (1/n⁴) − π
A = π (π⁴/90) − π
A = π⁵/90 − π

Which of the following sequence of transformations takes point J(9, 1) to J’(-3, 7)?
reflected across x-axis and translated (x, y) → (x - 2, y - 2)
translated (x, y) → (x - 2, y + 2) and rotated 270° counterclockwise about the origin
