Which is an equation of the line that passes through (–1, –5) and (–3, –7)?
nadya68 [22]

For this case we have that by definition, an equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points through which the line passes, then we find the slope:

(x1, y1): (- 1, -5)\\(x2, y2): (- 3, -7)

m = \frac {y2-y1} {x2-x1} = \frac {-7 - (- 5)} {- 3 - (- 1)} = \frac {-7 + 5} {- 3 + 1} = \frac {-2} {- 2} = 1

Then, the equation is of the form:

y = x + b

We substitute a point and find b:-5 = -1 + b\\-5 + 1 = b\\b = -4

Finally we have:

y = x-4

Answer:

Option B

If the diameter of a circle is 5 centimeters, how long is the arc sub tended by an angle measuring 60 degrees?
jenyasd209 [6]

Answer:

3/5pi

Step-by-step explanation:

The formula of getting the arc length is

arc length = angle * pi / 180 * r

arc length = 60 * pi / 180 * 5

arc length = 300 * pi / 180

arc length = 5pi / 3

Solve for x in the equation x squared 20 x 100 = 36. x = –16 or x = –4 x = –10 x = –8 x = 4 or x = 16
spin [16.1K]

Possible values of x is -4 or -16

<h3>How to solve?</h3>

{x}^2 + 20x +100 = 36

\\{x}^2 + 20x + 100-36 = 0

\\{x}^2 + 20x + 64 = 0

Using middle term split

In this method splitting of middle term in to two factors, In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term.

{x}^2 + 4x + 16x + 64 = 0

x(x+4) + 16(x+4) = 0

taking common (x+4)

(x+4)(x+16) = 0

Either

x+4 = 0

⇒ x = -4

or (x+16) = 0

⇒ x = -16

Thus possible values of x is -4 or -16
