TEA [102]2 years ago

Answer: See explanation

Step-by-step explanation:

Point slope form: y - y₁ = m (x - x₁)

y₁ = 6

x₁ = -7

y - 6 = -1 (x - [-7])

y - 6 = -1 (x + 7)

y - 6 = -1x - 7

Add 6 to both sides

y = -1x - 1    <em>or    </em>y = -x -1

Slope intercept form: y = mx + b

m = -1

b = 6

y = -1x + 6  <em>or   </em>y = -x + 6

Standard form: Ax + By = C

Change slope intercept form into _x + _y = c

Slope intercept form: y = -x + 6

Standard form:

y = -x + 6

Add x to both sides

x + y = 6    <em>or   </em>-x - y = -6

Hope I helped!

Answer:

17576

Step-by-step explanation:

As L can be anything from A to Z , there are 26 combinations for that and as repetition is allowed, for second and third letters, we again have 26 combinations available and thus 26×26×26=17576 combinations for letters.

Colton has watched 222 comedy movies for every 333 other movies. He has watched 303030 total movies.
Sedaia [141]

The total ratio is 5

The number of comedy movies watched is 12

The number of other movies watched is 18

<h3>What is a ratio?</h3>

Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. Therefore,

He has watched 2 comedy movies for every 3 other movies. The total movies he has watched is 30. Therefore,

  • 2:3

Ratio of comedy to total movies is as follows:

  • 2 : 5

number of comedy movies watched = 2 / 5 × 30 = 60 / 5 = 12

number of other movies watched = 3 / 5 × 30 = 90 / 5 = 18

Therefore,

total ratio = 5

number of comedy movies watched = 12

number of other movies watched = 18

Find the area of a circle circumscribed about an equilateral triangle whose side is 18 inches long
beks73 [17]

let's recall that an equilateral triangle has all interior angles of 60°.

Check the picture below.

so as you can see, 2√3 = x = r, namely the radius of the circle.

\bf \textit{area of a circle}\\\\ A=\pi r^2\qquad \qquad \implies A=\pi (2\sqrt{3})^2\implies A=\pi (2^2)(\sqrt{3})^2\implies A=12\pi
