 A line segment is represented (written) using letters for the start point and the end point, as in QR:  QR is the line segment connecting Q to R.  This is the most common case.


Expecially when we're not talking about points on a given line, a line can be refered to by any arbitrary name, such as "line f."

A line passes through the points (–5, 2) and (10, –1). Which is the equation of the line?
LenKa [72]
We have y - 2 = m(x + 5), where m = (-1 - 2)/(10 + 5) = -3/15 = -1/5;
Then y - 2 = (-1/5)(x + 5);
5y - 10 = (-1)(x + 5);
5y - 10 = -x - 5;
x + 5y - 5 = 0 is the equation of the line.

Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x
anyanavicka [17]

Answer:

x = 7.2

Step-by-step explanation:

Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.

Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}

(Assuming x is greater than 1.7}

Given that, x + 3.8 = 2(x - 1.7)

⇒ x + 3.8 = 2x - 3.4

⇒ x = 7.2 (Answer)

Suppose a rectangular garden plot has a length that can be expressed as x+2 feet and a width expressed as x+7 feet. Write a poly
mafiozo [28]

Answer:

Area = x^2 + 9x + 14

Perimeter = 4x + 18

Step-by-step explanation:

Given:

Length of rectangular garden = (x + 2) ft

Width = (x + 7) ft

Required:

a. Polynomial expression of the area of the garden

b. Polynomial expression of the perimeter of the garden

SOLUTION:

Area of the rectangular garden = length × width

Area = (x + 2)(x + 7)

Expand using the distributive property of multiplication

Area = x(x + 7) +2(x + 7)

Area = x^2 + 7x + 2x + 14

Area = x^2 + 9x + 14

Perimeter = 2(length) + 2(width)

Perimeter = 2(x + 2) + 2(x + 7)

Perimeter = 2x + 4 + 2x + 14

Collect like terms

Perimeter = 2x + 2x + 4 + 14

Perimeter = 4x + 18
