A line has a slope of – 1/7 and passes through the point (4,5). What is its equation in point-slope form?

Answers

Answer 1

Answer:

y-5=-1/7(x-4)

Step-by-step explanation:

The equation of the line in point-slope form is y-5=-1/7(x-4)

Answer 2

Answer:

y = -1/7 x + 39/7

Step-by-step explanation:

An equation in point slope form is

y = mx+b  where m is the slope and b is the y intercept

We are given the slope

y = -1/7 x + b

Substitute in the point for x and y and solve for b

5 = -1/7(4) +b

5 = -4/7 +b

5 + 4/7 = b

5*7/7 + 4/7 = b

35/7 + 4/7 = b

39/7 = b

The equation is

y = -1/7 x + 39/7

Answers

The value of YZ = 2 units.

What are collinear points?

The Latin words "col" and "linear" are combined to form the word "colinear." "Col" stands for "together," and "Linear" is a line. Collinear points are hence points that are situated along a single line. Numerous instances of collinearity can be observed in daily life, such as a line of pupils standing together.

Given X, Y, and Z are collinear. Y is between X and Z.

so XY + YZ = XZ

given XY = 12 units and XZ = 14 units

XY + YZ = XZ

12 + YZ = 14

YZ = 14 - 12

YZ = 2 units

A wheelchair ramp is to be built beside the steps to the campus library. Find the angle of elevation of the 23-foot ramp, to the nearest tenth of a degree, if its fi nal height is 6 feet.

Answers

The angle of elevation of the ramp is 28.6 degrees.

If the ramp's final height is 6 feet, calculate the ramp's angle of elevation to the nearest tenth of a degree.The angle of elevation of the ramp is the angle formed by the ramp to the horizontal ground.It is also known as the angle of inclination. To find the angle, the following equation is used:

Tan = (Change in Height) / (Length of Ramp)

Therefore, using the given information, the angle of elevation of the 23-foot ramp is:

Tan = (6 feet) / (23 feet)

Tan = 0.26

= 14.5° (to the nearest tenth of a degree)

Therefore, the angle of elevation of the 23-foot ramp is 14.5°.

The angle of elevation of the 23-foot ramp is 15.7 degrees to the nearest tenth of a degree.This can be found using the equation for finding the angle of elevation of an incline, which is tan θ = rise/run.In this case, the rise is 6 feet (the final height of the ramp) and the run is 23 feet (the length of the ramp).Therefore, the equation becomes tan θ = 6/23, and the angle of elevation can be found by solving for θ.Using a calculator, this value turns out to be 15.7 degrees.

At a banquet hall there are 25 tables that seat 4 people and 30 tables that seat 6 people. There are no other tables in the banquet hall. What is the ratio of the number of tables that seat 4 people to the total number of tables in the banquet hall?​

Answers

Answer:

1:11

Step-by-step explanation:

We know

There are 25 tables that seat 4 people

First, we find the total number of tables by taking

25 + 30 = 55 tables

Then we find the ratio of tables that seat 4 people to the total number of tables by

5 / 55 = 1/11 = 1:11

So, the ratio is 1:11

The transformation of the function is given by reflection along y axis and a translation of 5 units up

What is Reflection?

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the transformation be represented as A

Now , the equation will be

Let the triangle be represented as ΔODG

Now , the coordinates of ΔODG is

Now , the transformed triangle is ΔACT

The coordinates of ΔACT is

A = A ( 1 , 3 )

C = C ( 5 , 2 )

T = T ( 2 , 1 )

Now , on reflecting the triangle ΔODG along y axis , we get

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse

So , the coordinates of triangle O'D'G' , we get

O' = O' ( 1 , -2 )

D' = D' ( 5 , -3 )

G = G' ( 2 , -4 )

Now , translating the triangle ΔO'D'G' up by 5 units , we get

The y coordinate of the triangle gets incremented by 5

So ,

A = O' ( 1 , -2 + 5 )

C = C ( 5 , -3 + 5 )

T = T ( 2 , -4 + 5 )

And , the coordinates of the triangle ΔACT is

A = A ( 1 , 3 )

C = C ( 5 , 2 )

T = T ( 2 , 1 )

A singular plane and square are obtained in Euclidean geometry when the edges are not collinear. Any triangle that has three sides and three corners is a polygon.

Three line segments have measures of 18 units, 12 units, and 10 units. Will the segments form a triangle?



Does it form a triangle?

Answers

No, the segments will not form a triangle based on the line segments provided.

For three line segments to form a triangle, they must satisfy the triangle inequality theorem. The triangle inequality theorem states that for any triangle, the sum of the lengths of any two sides of the triangle must be greater than the length of the third side.

This is because if the sum of the lengths of any two sides is less than or equal to the third side, it would not be possible to form a triangle with those side lengths, as the two shorter sides would not be able to reach the longer side to form the triangle.

In this case, the sum of the two shorter segments (12 units + 10 units) is 22 units, which is less than the measure of the longest segment (18 units). Therefore, the three segments will not form a triangle.

Solve for x in the equation 2^(2x-1)x[1/8]^(1-x)=4^(3x+1)​

Answers

Answer: x=-6

Step-by-step explanation:

[tex]\displaystyle\\2^{2x-1}*(\frac{1}{8} )^{1-x}=4^{3x+1}\\\\2^{2x-1}*8^{(-1)(1-x)}=(2^2)^{3x+1}\\\\2^{2x-1}*(2^3)^{x-1}=2^{2*(3x+1)}\\\\2^{2x-1}*2^{3*(x-1)}=2^{6x+2}\\\\2^{2x-1}*2^{3x-3}=2^{6x+2}\\\\2^{2x-1+3x-3}=2^{6x+2}\\\\2^{5x-4}=2^{6x+2}\\\\Hence,\\\\5x-4=6x+2\\\\5x-4-2=6x+2-2\\\\5x-6=6x\\\\5x-6-5x=6x-5x\\\\-6=x\\\\Thus,\ x=-6[/tex]

Answer:

Step-by-step explanation:

We have:

2^(2x-1) x [1/8]^(1-x) = 4^(3x+1)

2^(2x-1) x [1/2³]^(1-x) = 2²^(3x+1)

2^(2x-1) x 2^-3+3x = 2^6x+2

2^5x-4 = 2^6x+2

on comparing both sides we get :

5x-4 = 6x +2

x = -6
