Write various of the equation of a line that passes through (-6, 3) and has a slope of - 1/3
pishuonlain [190]

Answer:

\large\boxed{y-3=-\dfrac{1}{3}(x+6)-\text{point-slope form}}\\\boxed{y=-\dfrac{1}{3}x+1-\text{slope-intercept form}}\\\boxed{x+3y=3-\text{standard form}}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

We have

m=-\dfrac{1}{3},\ (-6,\ 3)\to x_1=-6,\ y_1=3

Substitute:

y-3=-\dfrac{1}{3}(x-(-6))\\\\y-3=-\dfrac{1}{3}(x+6)

Convert to the slope-intercept form

y=mx+b

y-3=-\dfrac{1}{3}(x+6)           <em>use the distributive property</em>

y-3=-\dfrac{1}{3}x-2           <em>add 3 to both sides</em>

y=-\dfrac{1}{3}x+1

Convert to the standard form

Ax+By=C

y=-\dfrac{1}{3}x+1           <em>multiply both sides by 3</em>

3y=-x+3             <em>add x to both sides</em>

x+3y=3

Can anyone help me with this?
siniylev [52]

Answer:

1.  280/11

2. 1700/11

3. 280/11

4. 3600

5. 360

Step-by-step explanation:

Let n = sides of a regular polygon

For these problems, n = 22 because there are 22 sides.

I am going to write the formulas needed for each question below.

  1. 360/n
  2. 180 - 360/n
  3. 360/n
  4. 180(n-2)
  5. 360 (isn't affected by n)

To solve, just plug in N with 22.

These formulas are very easy to prove and I recommend if you have time try to prove these.

What is the value of a
liraira [26]

Answer:

b = 10

Step-by-step explanation:

In this question we have identified that b  ( or short leg ) = 5 brainly.com/question/23589050

In the image provided in that question the, we are told that the hypotenuse = short leg times 2

If we have identified that the short leg = 5 then the hypotenuse = 5 * 2 which is equal to 10
