If LM=41-2x and NP=7x+5, find LM

Answers

Answer:
LM = 33 units

Explanation:
From the drawing:
LM = NP
41 - 2x = 7x + 5
41 - 5 = 7x + 2x
36 = 9x
x = 9

This means that:
LM = 41 - 2x
LM = 41 - 2(4)
LM = 33 units

What is the equation of the line that passes through the point (4,7) and has a slope of 0?

Answers

The equation would be,

y = 0x + 7

or simplified,

y = 7

The equation of the line with a slope of 0 passing through the point (4, 7) is: y = 7.

What is the equation of the line?

To find the equation of a line with a slope of 0 that passes through the point (4, 7), you can use the point-slope form of a line, which is:

y - y1 = m(x - x1)

In this case, the slope (m) is 0, and the point (x1, y1) is (4, 7).

So, the equation becomes:

y - 7 = 0(x - 4)

Since the slope is 0, the equation simplifies to:

y - 7 = 0

Now, add 7 to both sides to isolate "y":

y = 7

So, the equation of the line is simply:

y = 7

Write and solve an equation to answer the question. 83% of 20 is what number a

Answers

Of means multiply
(83/100) * 20
166 / 100
16.6 <<<<answer.

Final answer:

83% of 20 is 16.6.

Explanation:

To find 83% of 20, we need to understand that percent means per hundred.

So, to calculate 83% of a number, we can convert the percentage to a decimal by dividing by 100 and then multiply by the number.

In this case, the equation to find 83% of 20 is:

(83 ÷ 100) × 20 = x

Which simplifies to:

0.83 × 20 = x

Now, we do the multiplication:

0.83 × 20 = 16.6

Therefore, 83% of 20 is 16.6.

"write an equation in slope-intercept form of the line satisfying the given conditions."

The line passes through (-3,2) and is parallel to the line whose equation is y = 4x + 1.

How do I do this problem? Show all work.

Answers

Hi there,

Let's get started,

The line is parallel to the line whose equation is y = 4x + 1.

So the slope will be the same.

The equation that would be possible is :

y = 4x + c

By the way, we know that the line passes through (-3 ; 2).

We just have to substitute these values in the equation in order to find the value of c.

(x ; y) ==> x = -3 and y = 2

Let's do this then,

2 = 4(-3) + c

c = 2 - 4(-3)
c = 2 + 12
c = 14

In short, the answer would be :
y = 4x + 14.

Hope this helps !

Photon

Hey there :)

The line with coordinates ( -3 , 2 ) is parallel to the line y = 4x + 1

Being Parallel means, both have the same slope
The slope is 4

The slope-intercept form is : y = mx + b {m is the slope and b is the y-intercept}

y - y₁ = m ( x - x₁ )

y - 2 = 4 ( x - (-3) )
minus and minus becomes addition
y - 2 = 4 ( x + 3 )
distribute 4 into the parenthesis
y - 2 = 4x + 12
+ 2 + 2

y = 4x + 14

Answers

Final answer:

The question is about finding the charge on different points using Coulomb's law. The charges at R and T are approximately the same, whereas S has about twice the charge based on the distances provided.

Explanation:

The student's question pertains to the concept of electric fields and forces in physics, specifically in the context of the Coulomb's law which defines the relationship between two charged objects. The equation used is derived from Coulomb's law, which is q1q2/r², where q represents the charges and r is the distance between them. Since qr/d² = qs/D², and taking into account the given distances (D as 6 units and d as 4 units), we conclude that the charge on S is about twice as much as that on R and T given that D²/d² equals 2.25.
