Answer:

y+6 = -2(x-4)

Step-by-step explanation:

Point slope form is given by

(y-y1) = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

(y - -6) = -2( x-4)

y+6 = -2(x-4)

ohaa [14]

Answer:

The y-intercept is 40. This is the cost of registration ⇒ last answer

Step-by-step explanation:

* Lets explain how to solve the problem

- Patrick wanted to gather data about the cost of joining a community

 pool in his area

- He plotted the data and determined that the average community

 pool membership cost consists of a one-time registration fee and

 a monthly fee

∴ The cost consists of two parts:

# Part A: one-time registration fee, it is a fixed amount not depend on

  any other condition

# Part B: monthly fee, it depends on the number of months

- He modeled that by the equation y = 15 x + 40, where

# y is the cost for the membership

# 15 is the monthly fee

# x is the number of months

# 40 is the one-time registration

- The form of the equation is y = mx + c, where c is the y-intercept

∴ The y-intercept in the equation y = 15 x + 40 is 40

∴ The y-intercept is the one-time registration fee

* The y-intercept is 40. This is the cost of registration

Plz help me on this quick
Studentka2010 [4]

Answer: The third one

Step-by-step explanation: We can eliminate the first one right off the bat sinc we see that -4 has two outputs. Next, the graph's equation has no slope (x=3) so the input is all the same. Thirdly, the table shows a relationship between x and y and the numbers don't have a pattern that shows more than one output or input for a number. The fourth option are simply coordinates, it doesn't particularly tell us that all the coordinates are related to each other.

HELP!! What is the exact value of Tangent (pi/12)
Vlad1618 [11]

Answer:

2 - sqrt(3)

Step-by-step explanation:

Split pi/12 into two angles where the values of the six trigonometric functions are known.

tan (pi/4 - pi/6)

Apply the difference of angles identity

\frac{tan(pi/4) - tan(pi/6)}{1 + tan(pi/4)tan(pi/6)}

tan(pi/4) = 1 , tan(pi/6) = (sqroot3)/3

Plug in and Simplify

\frac{1-\frac{\sqrt{3} }{3} }{1+1\frac{\sqrt{3} }{3} }

\frac{\frac{3-\sqrt{3} }{3} }{\frac{3+\sqrt{3} }{3} }

\frac{3-\sqrt{3} }{3} *\frac{3}{3+\sqrt{3} }

\frac{3-\sqrt{3} }{3+\sqrt{3}} Need to multiply this by \frac{3+\sqrt{3} }{3+\sqrt{3} }

Expand and simplify numerator: \frac{6}{(3+\sqrt{3} )^{2} }

Expand and simplify denominator: \frac{6}{12+6\sqrt{3}}

Cancel the common factor: \frac{1}{2+\sqrt{3}}
