how do you solve this? need help asap!! find y!!
Answer:
x = 21 degrees
y = 66 degrees
Step-by-step explanation:
Supplementary angles sum 180 degrees and complementary angles sum 90 degrees.
The first two upper angles are supplementary since they complete half a turn of a circle.
The relation is
(3x+5)+(6x-14)=180.
Joining like terms
9x-9=180
Dividing by 9
x - 1= 20 =>
x = 21 degrees
The first and the last angle are the same because they are formed by two parallel lines to a common side, so
3x-5=y-8 or
y=3x+3 = 63+3 =>
y = 66 degrees
If the probability of surviving a head on car accident at 55 mph is 0.097, then what is the probability of not surviving
The probability of not surviving a head-on car accident is: 0.903

The probabilities of occurrence and non-occurrence of an event add up to one.
If p is the probability that an even will happen and q is the probability that it will not happen
Then

Will the point (2, 6) be on the graph of y = 3x?
A. No, because an equation does not have points.
B. Yes, because x = 6 and y = 2 is a solution to the equation.
C. Yes, because x = 2 and y = 6 is a solution to the equation.
D. No, because x = 6 and y = 2 does not make the equation true.
Answer:
Yes, because x = 2 and y = 6 is a solution to the equation.
The point (2, 6) does lie on the graph of the equation y = 3x because when you substitute x = 2 and y = 6 into the equation, it holds true (6=3*2). Hence, yes, because x = 2 and y = 6 is a solution to the equation.
Explanation:To determine if the point (2, 6) is on the graph of y = 3x, you would need to substitute the values of x and y into the equation and see if it holds true. In this case, if we substitute x = 2 and y = 6, we get 6 = 3*2, which simplifies to 6 = 6. This shows that the equation is true, therefore, the point (2, 6) lies on the graph of y = 3x. So the correct answer is C: Yes, because x = 2 and y = 6 is a solution to the equation.

What is the solution to the system of equations? 3x-6y=-12 " " x-2y=10 Use the substitution method to justify that the given system of equations has no solution. What do you know about the two lines in this system of equations?
The two lines in this system of equations are parallel
Step-by-step explanation:
Let us revise the relation between 2 lines
If the system of linear equations has one solution, then the two line are intersected If the system of linear equations has no solution, then the two line are parallelIf the system of linear equations has many solutions, then the two line are coincide (over each other)∵ The system of equation is
3x - 6y = -12 ⇒ (1)
x - 2y = 10 ⇒ (2)
To solve the system using the substitution method, find x in terms of y in equation (2)
∵ x - 2y = 10
- Add 2y to both sides
∴ x = 2y + 10 ⇒ (3)
Substitute x in equation (1) by equation (3)
∵ 3(2y + 10) - 6y = -12
- Simplify the left hand side
∴ 6y + 30 - 6y = -12
- Add like terms in the left hand side
∴ 30 = -12
∴ The left hand side ≠ the right hand side
∴ There is no solution for the system of equations
∴ The system of equations represents two parallel lines

Using substitution method, we can see the system of equation has no solution and graphically, the lines are parallel to each other and don't intersect.
What is the solution to the system of linear equations?To solve the system of equations using the substitution method, we can solve one equation for one variable and substitute it into the other equation.
Let's start by solving the second equation for x:
x - 2y = 10
x = 2y + 10
Now we substitute this expression for x in the first equation:
3x - 6y = -12
3(2y + 10) - 6y = -12
6y + 30 - 6y = -12
30 = -12
Since the equation 30 = -12 is not true, we have reached a contradiction. This means that the system of equations has no solution.
Regarding the two lines in this system of equations, we can observe that they are parallel and they don't intersect with one another.

Please help ASAP. Quadrilateral CDEF is inscribed in circle A. If the m∠C = 7x + 11° and m∠E = 7x + 1°, what is the measure of ∠E?
A) 95
B) 99
C) 81
D) 85
Answer:
The answer is D
Step-by-step explanation:
∠C + ∠E = 180°(consecutive angles)
7x +11° + 7x + 1° = 180°
14x + 12° = 180°
14x = 168°
x = 12°
∠E = 7x + 1°
= 7(12°) + 1
= 85°
The measure of ∠E is 85 degrees
How to determine the measure of E?To calculate the measure of E, we start by calculating the value of x using:
∠C + ∠E = 180° (consecutive angles of cyclic quadrilateral)
So, we have:
7x +11° + 7x + 1° = 180°
Evaluate the like terms
14x + 12° = 180°
Subtract 12 from both sides
14x = 168°
Divide both sides by 14
x = 12°
Recall that:
∠E = 7x + 1°
Substitute 12 for x
∠E = 7(12°) + 1
Evaluate
∠E = 85°
Hence, the measure of ∠E is 85 degrees

If the engine in a 1200 kg car could produce 10,000 N to accelerate from 0 to 27
m/s, how much time would that take?
Answer:
The time taken by engine of the car to accelerate is 3.24 seconds
Step-by-step explanation:
Given as :
The mass of the car = 1200 kg
The Force applied by engine to accelerate = 10, 000 N
The change in velocity = [tex]v_2[/tex] - [tex]v_1[/tex] = 27 m/s
Let The time taken by engine = t sec
And Let The acceleration = a m/s²
Now,
∵ Force is define as the product of mass and acceleration
I.e F = mass × acceleration
or, F = 1200 × a
or, 10,000 = 1200 × a
∴ a = [tex]\frac{10,000}{1200}[/tex] m/s²
I.e a = 8.33 m/s²
Now , Again
∵ Acceleration is define as the rate of change of velocity
I.e a = [tex]\dfrac{v_2-v_1}{t}[/tex]
or, a = [tex]\dfrac{27-0}{t}[/tex]
Or, t = [tex]\dfrac{27}{a}[/tex]
I.e t = [tex]\dfrac{27}{8.33}[/tex]
∴ t = 3.24 sec
So, The time taken = 3.24 seconds
Hence The time taken by engine of the car to accelerate is 3.24 seconds . Answer
Why is 3.4 * 910 is NOT correct scientific notation?
Explanation:
Scientific Notation is number between 1-10 multiplied by 10[tex]^{#}[/tex] (or e#) This has the 1-10 right but the other number incorrect.
The correct scientific notation is 3.4e+9.
Need to explanation why is 3.4 * 910 is not correct scientific notation.
Scientific notation means the longer value coded to short terms like 34000 to 3.4e+4.
Here 3.4*910 does not represent any thing because the correct manner for the scientific notation is ae + b. Where a = value and b =power to the 10.
so the correct scientific notation is 3.4e+9.

what value of k makes the factor (x+3) a factor of the function f(x)=3x^3-2x+k?
Final answer:
To find the value of k that makes (x+3) a factor of the function f(x)=3x^3-2x+k, substitute x=-3 into the equation, leading to the solution k=75.
Explanation:
The question asks for the value of k that makes (x+3) a factor of the function f(x)=3x³-2x+k. To solve this, we use the fact that if (x+3) is a factor of f(x), then f(-3)=0. Therefore, we substitute x=-3 into the equation and solve for k.
Substituting x=-3 into f(x)=3x³-2x+k gives:
f(-3) = 3(-3)³- 2(-3) + k = -81 + 6 + k
Since f(-3)=0, we have -75 + k = 0
Thus, k = 75
This computation shows that the value of k that makes (x+3) a factor of the given function is 75.

A used-boat dealership buys a boat for $2900 and then sells it for $4500. What is the percent increase?(Round to the nearest whole number as needed.)
Answer:
55%
Step-by-step explanation:
We have to divide the new price by the original price
4500/2900 = ca. 1.5517
Take away 100% from this answer and we get 0.5517 over the original price
This is the same as 55.17% can be rounded to 55%
To find the percent increase in the boat's price, subtract the original price from the selling price, divide by the original price, then multiply by 100 and round to the nearest whole number. The calculation shows about a 55% increase from the original price of $2900 to the selling price of $4500.
Explanation:To calculate the percent increase, you would subtract the original price of the boat from the selling price and then divide by the original price to get the fraction of the increase. Finally, you multiply this fraction by 100 to convert it to a percentage. Using the given numbers: The original price is $2900, and the selling price is $4500.
Subtract the original price from the selling price: $4500 - $2900 = $1600Divide the increase by the original price: $1600 / $2900 ≈ 0.5517241379Multiply by 100 to convert to a percentage: 0.5517241379 × 100 ≈ 55.17%When you round this to the nearest whole number, you get a percent increase of 55%.
