y=2x+7. In order to create an equation that is parallel to the old equation, Julie must make sure that her new equation has the same slope as the old equation. The slope of the old equation is 2, so Julie's new equation should also have a slope of 2. Additionally, she must make sure that the y-intercept of her new equation is the same as the given data point, which is (6, 7). Therefore, the new equation should be in the form y = 2x + b, where b is the y-intercept. Plugging in the values from the given data point, we get y = 2x + 7. This equation is parallel to the old equation and passes through the given data point, so it is the correct answer.
Answer:
The answer to the question is that the new equation that is parallel to the old equation and passes through the point (6, 7) is y = 2x - 5.
Step-by-step explanation:
To create an equation that is parallel to the old equation, you need to use the same slope. This means that your new equation should be y = 2x + b, where b is a constant. Since the point (6, 7) is on the new equation, you can plug those values into the equation to find b.

Answer the questions about the following polynomial..... please help!
Answer:
x⁵ - 1/3x² -1
Step-by-step explanation:
In order to write polynomials in standard form:
1) Find the degree (power) of each term
2) Arrange them in descending order (largest to smallest)
We have : -1 + x⁵ - 1/3x²
The degree of -1 is 0 since there is no power.
The degree of x⁵ is 5.
The degree of - 1/3x² is 2.
Now arranging them in descending order:
x⁵ has the largest degree, followed by - 1/3x² and then -1, so the polynomial in standard form is:
x⁵ - 1/3x² -1
A train leaves the station at time t=0. Traveling at a constant speed, the train travels 260 kilometers in 2 hours. Answer parts a and b
The function which can be used to find the relation between distance and time is f(t) = 130t.
As we know the train travels 260 kilometers in 2 hours,
then the distance traveled in one hour will be 130 kilometers.
distance = 130
when time = 0 ,
distance also = 0 , as the train has not started moving yet.
Then , the function which can tell bout the relation will be ,
f(t) = 130t
where d = f(t)
Distance is a scalar quantity which tells us about how far an object is from its starting position. Distance don't have a direction.

if x^2 + y^2 = 289, find the value of dy/dt at (8,15)
Answer: a)
Step-by-step explanation:
To find [tex]\frac{dy}{dx}[/tex], we will have to use implicit differentiation, and because the base is [tex]dx[/tex], we will take the deriviative of both sides with respect to [tex]x[/tex].
To derive [tex]y[/tex] with respect to [tex]x[/tex], just derive the term with respect to y then multiply the term with [tex]\frac{dy}{dx}[/tex].
So [tex]\frac{d}{dx} x^{2}[/tex] is just [tex]2x[/tex], [tex]\frac{d}{dx} y^{2}[/tex] is [tex]2y \frac{dy}{dx}[/tex], and [tex]\frac{d}{dx} 289[/tex] is 0. Now substitue each term with it's deriviative.
[tex]2x + 2y \frac{dy}{dx} = 0[/tex]
Now, just solve for [tex]\frac{dy}{dx}[/tex] when [tex]x[/tex] is 8 and [tex]y[/tex] is 15
[tex]2(8) + 2(15)\frac{dy}{dx} = 0[/tex]
[tex]16 + 30\frac{dy}{dx} = 0[/tex]
[tex]\frac{dy}{dx} = \frac{-16}{30} = \frac{-8}{15}[/tex]
So the answer is choice a)

How do I solve for x in #34 and #35?
Answer:
34. x = 3 1/3
35. x = 5.2
Step-by-step explanation:
Given figures involving triangles with angle bisectors and parallel segments, you want to solve for x.
In each case, you need to make use of two proportional relationships. An angle bisector divides the triangle proportionally. An segment parallel to one side of the triangle divides it proportionally.
34.Using the angle bisector relation, you have ...
QP/PT = QS/ST
x/3 = 5/ST ⇒ x = 15/ST
Using the parallel segment relation, you have ...
PT/QR = ST/SR
3/2 = ST/3 ⇒ ST = 9/2
Using the value of ST in the equation for x gives ...
x = 15/(9/2) = 30/9 = 10/3
x = 3 1/3
35.Using the angle bisector relation, you have ...
EF/ED = CF/CD
7.2/9 = CF/6 ⇒ CF = 6(7.2/9) = 4.8
Using the parallel segment relation, you have ...
CB/BA = CF/FE
x/7.8 = 4.8/7.2
x = 7.8(4.8/7.2)
x = 5.2
__
Additional comment
In each case, we assigned a numerical value to the intermediate variable (ST, CF). We didn't actually need to do that.

Answer:
1
Step-by-step explanation:
For function f(x), the average rate of change from x = a to x = b is:
average rate of change = (f(b) - f(a))/(b - a)

a fast-food restaurant runs a promotion in which certain food items come with game pieces. according to the restaurant, 1 in 4 game pieces is a winner. if jeff keeps playing until he wins a prize, what is the probability that he has to play the game exactly 5 times?
The probability that Jeff has to play the game exactly 5 times i.e he keeps playing until he wins prize is (0.25)⁵.
We have, a fast-food restaurant runs a promotion which consists some food items with games pieces. 1 in 4 game pieces is a winner. This means, probability of winning game or sucess (p) = 1/4 . Since number of trials is fixed, trials are independent and probability of success is constant in each trial, we can use Binomial distribution. The Binomial distribution probability formula is
P(X= x) = ⁿCₓ(p)ˣ(1-p)⁽ⁿ⁻ˣ⁾
where,n --> number of trials
p --> probability of success
x --> number of times for a specific outcome within n trials
ⁿCₓ --> number of combinations
we have calculate the probability that he has to play the game exactly 5 times, i.e
x = 5 . Jeff keeps playing until he wins and he wins when he play exactly 5 times so,n= 5
Now, plugging all known values in above formula we get,
P(X= 5) = ⁵C₅(0.25)⁵(1-0.25)⁰
=> P(X= 5) = ⁵C₅(0.25)⁵(0.75)⁰
=> P(X= 5) = 1× (0.25)⁵× 1 = (0.25)⁵

2. m<COD = 90 degree
3. m<BOD = 130 degree
4. m<AOD = 180 degree
Step-by-step explanation:
1. We see that <AOB has one leg at 0 and the other leg at 50 degrees, so the <AOB is 50 degrees.
2. We see that <COD has one leg at 0 and the other leg at 90 degrees, so the <COD is 90 degrees
3. We see that <BOD has one leg at 50 and the other leg at 180 leg, so the <BOD is 180 - 50 = 130 degree
4/ We see that <AOD has one leg at 0 and the other leg at 180 degrees, so the <AOD is 180 - 0 = 180 degrees
a line with a slope of 2 passes through the points (10,8) and (w,6). what is the value of w?
Answer:
w = 9
Step-by-step explanation:
Use a slope formula to solve. Subtract the y's put that on top and subtract x's and put that on the bottom. This calc should equal 2 that was given.
(8-6)/(10-w) = 2
2/(10-w) = 2
Cross-multiply.
2 = 2(10-w)
Distributive property
2 = 20 - 2w
Add 2w
2 + 2w = 20
Subtract 2
2w = 18
divide by 2
w = 18/2 = 9
Or you can logic it out...8-6 is 2 on top. Need a 1 on the bottom (bc 2/1 is 2) 10-9 is 1 for on the bottom. w = 1

An airplane is descending from 35600 ft at 3200ft per mile,
how long would it be until the plane reaches 18,000 ft? I dont remember the exact ft but i just need a example such as a equation to solve please! please help! T>T
Answer:
To calculate how long it will take for the plane to reach 18,000 ft, first find the difference between the plane's current altitude and its target altitude:
35,600 ft - 18,000 ft = 17,600 ft
Then, divide this difference by the rate of descent to find the time it will take for the plane to reach its target altitude:
17,600 ft / 3,200 ft/mile = 5.5 miles
Since the rate of descent is given in feet per mile, this result is equivalent to the time it will take for the plane to reach its target altitude. Therefore, it will take the plane 5.5 miles (or a similar amount of time) to reach 18,000 ft.

The percentage of buyers who paid between $17,000 and $18,000 is %___
The percentage of buyers who paid less than $16,000 is %__
Answer: If the prices paid for a model of a new car are approximately normally distributed with a mean of $17,000 and a standard deviation of $500, it means that the majority of the prices paid for the car will fall within a certain range around the mean. Specifically, approximately 68% of the prices paid will be within one standard deviation of the mean, which in this case would be between $16,500 and $17,500. Approximately 95% of the prices paid will be within two standard deviations of the mean, which would be between $16,000 and $18,000. And approximately 99.7% of the prices paid will be within three standard deviations of the mean, which would be between $15,500 and $18,500. This shows that the prices paid for the car are relatively consistent, with only a small percentage falling outside of the range determined by the mean and standard deviation.
