Chords AB and CD intersect at point E, AE = 10, EB = 4, and CE = 8. Therefore, ED = A) 4 B) 5 C) 6 D) 7
Answers
Answer with explanation:
It is given that two chords AB and CD intersect at point E.
Also, A E= 10, E B=4 , CE=8
So, By Intersecting chord Theorem
⇒A E × E B = CE × E D
⇒10 × 4= 8 × ED
⇒ 40 =8× DE
Dividing both sides by , 8 we get
DE= 5 unit
Option: B, DE=5 unit

You reach into a bag of coins and withdraw two coins without replacement. What is the probability you withdrew a nickel and then a dime if the bag held five pennies, ten nickels, and four dimes?
Answers
aaaaaaaaaaaaaaaaaaaaaa
Answer: [tex]\dfrac{20}{171}[/tex]
Step-by-step explanation:
Given : Number of nickels in the bag = 10
Number of dimes in the bag = 4
The total number of coins in the bag =[tex]10+4+5=19[/tex]
The probability of drawing nickel :-
[tex]\text{P(nickel)}=\dfrac{10}{19}[/tex]
Total number coins left = 18
The conditional probability of drawing dime, given that a nickel is already drawn :-
[tex]\text{P(dime}|\text{nickel)}=\dfrac{4}{18}[/tex]
Now, the probability you withdrew a nickel and then a dime is given by :-
[tex]\text{P(dime and nickel)}=\text{P(dime}|\text{nickel)}\times\text{P(nickel)}\\\\=\dfrac{10}{19}\times\dfrac{4}{18}=\dfrac{20}{171}[/tex]

PART 2...Solve the below system of equations using the best method. Please describe the method used [substitution, graphing, elimination, etc], and give your answer in the form (x,y).
1.) 7x + 2y = 4
y = -4x + 1
2.) 3x - 4y = 1
-2x + 3y = 1
Answers
7x + 2y = 4
y = -4x + 1
Substitute what y is equal to from the second equation into y of the first equation.
7x + 2(-4x + 1) = 4
7x - 8x + 2 = 4
-x + 2 = 4
-x = 2
x = -2
Now substitute x with -2 in the second original equation to find y.
y = -4x + 1
y = -4(-2) + 1
y = 8 + 1
y = 9
Solution: (-2, 9)
2.) The first equation has 3x. The second equation has -2x. Multiply the first equation by 2 and the second equation by 3 and add them to use the elimination method.
3x - 4y = 1
-2x + 3y = 1
6x - 8y = 2
-6x + 9y = 3
-----------------
y = 5
The first original equation has -4y, and the second original equation has 3y. Multiply the first equation by 3 and teh second by 4 and add them to eliminate y.
9x - 12y = 3
-8x + 12y = 4

Check out the attached image "figure 1". The graph of the line is shown in red. The red line is the equation y = -3x+4. The answer choices A through D are shown as blue points. Only point A = (1,7) is not on the red line. So point A is not a solution to the equation.
Answer: Choice A) (1,7)
=============================================
Problem 2)
First error is in step 3, specifically the "additive inverse" portion. It should be "additive property of equality" since we're adding 10x to both sides.
The second error is the reasoning in step 5. Instead of "symmetric property" it should be "subtraction property of equality".
The third error is all of line 7. We are not multiplying both sides by 6. Instead we divide both sides by 6. The reasoning should be "division property of equality"
Finally, the last error is the first column on line 8. The final answer should be x = 7 (since 42 divided by 6 = 7)
See the image attachment "figure 2" for the visual summary of the table, and what needs to be fixed.

Parallel slope of 8x+y=11
Answers
First, we must put this into slope-intercept form, just so that we see this better :)
Slope-intercept form : y=mx+b where m=slope, b=y-intercept.
Subtract 8x from both sides.
y = -8x + 11
-8 is in the "m" spot. Remember, m=slope :)
So, our slope is -8.
Remember, if 2 lines are parallel to one another, then they have the same slope.
So, the parallel slope of -8 is -8.
However, if 2 lines are perpendicular from one another, they have negative reciprocal slopes :)
~Hope I helped!~
Answer:
The slope parallel to this line is -8.
Step-by-step explanation:
That's because parallel lines have the same slope. Therefore to find the slope of a parallel line, we must first find the slope of this one. On order to do that, we need to solve for y and then look at the coefficient of x.
8x + y = 11
y = -8x + 11
Therefore, we know the slope to be -8, which means the parallel slope must also be -8.
Bob can do a job in 5 hours while Bill can do the same job in 8. How many hours would it take them, working together, to do this job?
Answers
Final answer:
Bob and Bill can complete the job together in approximately 3.08 hours by combining their individual rates of work, which are 1/5 and 1/8 jobs per hour respectively.
Explanation:
The question asks how long it would take Bob and Bill to complete a job if they worked together, with Bob being able to do it in 5 hours and Bill in 8 hours. To solve this, we calculate the rates at which Bob and Bill work and then combine these rates to find their combined rate.
Bob's rate is 1 job per 5 hours, or 1/5 jobs per hour. Bill's rate is 1 job per 8 hours, or 1/8 jobs per hour. When they work together, their combined rate is 1/5 + 1/8 = 8/40 + 5/40 = 13/40 jobs per hour.
To find the total time it takes for them to complete 1 job, we take the reciprocal of their combined rate: 1 / (13/40) = 40/13, which is approximately 3.08 hours.
Combining Bob and Bill's individual rates, it would take them approximately 3.08 hours to complete the job together.
Find out how long it would take Bob and Bill to do the job together:
Calculate individual rates.
Bob's rate: He can complete the job in 5 hours, meaning his rate is 1 job / 5 hours.
Bill's rate: He can complete the job in 8 hours, meaning his rate is 1 job / 8 hours.
Combine rates.
To find their combined rate, we simply add their individual rates: Combined rate = Bob's rate + Bill's rate Combined rate = (1 job / 5 hours) + (1 job / 8 hours)
Calculate combined time.
Now, divide 1 (representing the entire job) by the combined rate to find the total time they take working together: Time together = 1 / Combined rate Time together = 1 / ((1 job / 5 hours) + (1 job / 8 hours))
Simplify and express the answer.
This can be simplified to: Time together = 40 / 13 hours Time together ≈ 3.08 hours
Therefore, it would take Bob and Bill approximately 3.08 hours to complete the job together.

Answers
slope = (5 - (-1) / (-2 - 3) = -6/5
y = mx + b
slope(m) = -6/5
(3,-1)...x = 3 and y = -1
sub and find b, the y int
-1 = -6/5(3) + b
-1 = -18/5 + b
-1 + 18/5 = b
-5/5 + 18/5 = b
13/5 = b
so ur equation is : y = -6/5x + 13/5
To find the linear equation of a line passing through two given points, use the formula for the slope of a line to calculate the slope, then substitute this value, along with one of the given points, into the point-slope form of a line and solve for y.
Explanation:The subject of this question is the formulation of a linear equation, specifically a equation of a line passing through two given points (3, -1) and (-2, 5). The formula used to find the slope (m) of a line between two points is: m = (y2 - y1) / (x2 - x1). Use this formula to calculate the slope using these points(m = (5 - (-1)) / (-2 - 3) = -6/5) .
Next, using the point-slope form of a line, y - y1 = m(x - x1), we substitute m with the calculated slope, and (x1, y1) with one of the given points. (Let's use (3, -1), y - (-1) = -6/5(x - 3) simplifying this gives us the answer: y=-6/5x +13/5. Therefore, the correct answer is choice B: y=-6/5x +13/5.
