Which would be an equivalent way to write y= 2 - 3x ?
Fudgin [204]
The answer is B, because the numbers in the equation are 2, and -3x. The signs have to stay with the numbers they are with. So if you move the 3 to the front you have to keep the negative with it.

Please answer! it's more complicated than it looks!​
kifflom [539]

Answer:

1. 360

2. Yes because in a regular hexagon all angles are congruent so the exterior angles are as well

3. (i) 60 (ii) 120

4.

(i) 1. 360 2. Yes because in a regular octagon all angles are congruent so the exterior angles are as well 3. (i) 45 (ii) 135

(ii) 1. 360 2. Yes because in a regular 20-gon all angles are congruent so the exterior angles are as well 3. (i) 18 (ii) 162

Step-by-step explanation:

Works for each polygon

1. First take the number of sides and subtract it by 2 then multibly that by 180

6-2=4x180=720

Then divide by the number of angles and subrtact that number by 180 to find the measure of one exterior angle

720/6=120

180-120=60

Then multiply by the number of exterior angles

60x6=360

2. Regular polygons always have equal angles so the exterior angles are as well

3. Put in your numbers from earlier

(i) 60 (ii)120

Hope this helps! :)

P.S. Feel free to mark brainliest :)

Find the value of x.
vesna_86 [32]

Answer:

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

The graph of y = 3/x is reflected over the y-axis and then translated down 2 units to form f(x). Which is the graph of f(x)?
adoni [48]

ANSWER

Given

The equation is

y =\frac{3}{x}

The equation of a rectangular hyperbola is xy = c²

where c is constant

thus  above  is the equation of the rectangular hyperbola.

First case

y =\frac{3}{x}

the graph of this equation is shown below.  

Second case

y =\frac{3}{x}

is reflected over the y -axis

than the equation becomes

y =\frac{-3}{x}

the graph is shown below.  

Third Case

y =\frac{-3}{x}

translated down 2 units to form f(x)

than the equation becomes

y-2 =\frac{-3}{x}

The graph is shown below.
