The engineers designing the All Aboard Railroad between Boca Raton and Jupiter decide to create parallel tracks through this portion of the railway. To illustrate their plans to the county commission, they use a coordinate plane. The southbound track will have an equation of 2x + 5y = 15. What is the equation of the parallel northbound track that runs through the point (4, – 2)?

Answers

Answer:

there are no signs between the x and y and constant

it could be

2x+5y=15

2x+5y=-15

-2x+5y=15

2x-5y=15

for ax+by=c, the equation of a line paralell to that is

ax+by=d where a=a, b=b, and c and d are constants

(for this answer, I'm going to use 2x+5y=15)

given 2x+5y=15, the equation of a line paralell to that is 2x+5y=d

to find d, subsitute the point (4,-2), basically put 4 in for x and -2 for y to get the constant

2x+5y=d

2(4)+5(-2)=d

8-10=d

-2=d

the eqaution is 2x+5y=-2 (Only if the original equation is 2x+5y=-15

identify the slope of the line for the equation 1/6 x + 1/4

Answers

Answer:

y = 1/6x - 8/3

Step-by-step explanation:

The equation of a line in slope-intercept form is.

y = mx + b

where m represents the slope and b, the y-intercept.

Rearrange y + 2 = 1/6 (x - 4)  into this form

distribute bracket and simplify.

y + 2 = 1/6x - 2/3

⇒ y = 1/6x - 2/3 - 2

⇒ y = 1/6x - 8/3 ← in slope-intercept form

Felipe and Makayla each tried to solve the same
equation for x.
Original equation: 2x + 6 = 3x - 8
The result of Felipe's first step was -x + 6 = 8.
Describe the first step Felipe made to the equation

Answers

Felipe subtract 3x from both side to get rid of x on one side. Ik this isn’t part of the answer but the correct way to do this would be to subtract 2x from each side after adding 8 to each side of the equation

Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -

2x - 3x + 6 = 8

What is a function?

An expression in mathematics defines a relationship between one variable (the independent variable, x)  and another variable (the dependent variable, y). For example -

f(x) = 4x + 6

Given is the equation equating two functions as -

2x + 6 = 3x - 8

We have -

2x + 6 = 3x - 8

2x - 3x + 6 = 8

-x + 6 = 8

Therefore, Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -

2x - 3x + 6 = 8

A covered bridge is 8 yards long. In a painting for sale at a gallery, the bridge in the painting to the actual length of the bridge. One salesperson says the ratio in simplest form is 5/8. Another salesperson says the ratio in simplest form is 5/24. Which ratio is correct? What error leads to the incorrect ratio?

Answers

Answer:

The ratio that is correct is 5/24.

The error that leads to the incorrect ratio is working with the different units of length.

Step-by-step explanation:

Here is the complete question:

A covered bridge is 8 yards long. In a painting for sale at a​ gallery, the bridge is 5 feet long. A customer wants to know the ratio of the length of the bridge in the painting to the actual length of the bridge. One salesperson says the ratio in simplest form is 5/8 Another salesperson says the ratio in simplest form is 5/24 Which ratio is​ correct? What error leads to the incorrect​ ratio?

Step-by-step explanation:

From the question,

A covered bridge is 8 yards long and in a painting at the gallery, the bridge is 5 feet long.

To determine the ratio of the length of the bridge in the painting to the actual length of the bridge,

First, we will convert both lengths to the same unit and then divide the length of the bridge in the painting by the actual length of the bridge.

Convert 8 yards to feet

1 yard = 3 feet

∴ 8 yards = (8 × 3) feet = 24 feet

The actual length of the bridge is 24 feet

The length of the bridge in the painting is 5 feet

Hence, the ratio of the length of the bridge in the painting to the actual length of the bridge is 5 feet ÷ 24 feet = 5/24

Hence, the ratio that is correct is 5/24.

The error that leads to the incorrect ratio is working with the different units of length (that is, not converting both length to the same unit before determining the ratio).

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.
What is the measure of B?

Answers

I believe it is 74°. Because translations preserve size

The measure of the angle B is 74 degrees.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.

If triangle ABC is translated 2 units up and 2 units right, that means that all the vertices of the triangle are translated by the same units 2 up and 2 right.

The angle sum property of a triangle;

80 + 26 + B = 180

B = 180 - 106

B = 74

Therefore, the size and shape of the triangle wouldn't change.

The triangle A'B'C' will still have the same size and shape, and all the sides will have the same length.

Hence, the measure of the angle B is 74 degrees.

Which statement is modeled by 2p + 5 < 11
Group of answer choices

The sum of 5 and 2 times p is at least 11

5 added to the product of 2 and p is less than 11

2 times p plus 1 is at most 11

the product of 2 and p added to 5 is 11

Answers

Answer: 5 added to the product of 2 and P is less than 11

The reason for this is because the inequality multiples 2 and the variable p, which is the product. Then, you have to add 5 to the product of 2p. Since the sign is opened towards the 11, this indicates that the sum of 5 and 2 times p is less than 11. Hope that helps!

Answer:

x = 7

Step-by-step explanation:

What condition is necessary for AE and BF to be equal? In this situation, what is the relationship between AB and CD? What can you conclude

about parallel lines with regard to the distance between them? Use the word perpendicular in your answer.

Answers

Answer:

In order for line AE to equal line BF, m/DFB and m/CEA must both be 90°. When this occurs, line AB does not intersect line EF: the two lines are parallel. line AE and line BF represent the perpendicular distances between line AB and line CD. When the two lines are parallel, the perpendicular distance between them is the same throughout their length.

Step-by-step explanation:

Plato Sample Question

When the two lines are parallel, then the perpendicular distance between them is the same throughout their length.

How are parallel straight lines related?

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

In order for line AE to equal line BF, Angle DFB and Angle CEA must both be 90°.

When this occurs, line AB does not intersect line EF then the two lines are parallel.

Thus the line AE and line BF represent the perpendicular distances between line AB and line CD.

When the two lines are parallel, then the perpendicular distance between them is the same throughout their length.
