Briana is wrong. The 2 line cannot be parallel since their slopes are not the same. The slope of one line is 2 and the slope of the other is 2.5.

The other student is right. Just replace (9, 21.5) in both equations and it will satisfy both equation.

Let f(x) = 4x - 5 and g(x) = 6x - 3. Find f(x) - g(x).
professor190 [17]
F(X) = 4x - 5
G(X) = 6x - 3

F(x) - G(x)

(4x - 5) - (6x - 3)

4x - 5 - 6x + 3

-2x - 2

-2(X + 1).

I believe this would be the simplified solution.

Scrat [10]
1. 2700 degrees. 450 rotations in on minute is 450(360) degrees per minute. If you divide this by 60 you get 2700. 
2. 180 degrees. 4.3 rotations per minute is 4.3 times 360 degrees per minute. Multiply that times 5, and divide the answer by 360 and you get 21.5, which means he is 180 degrees from his starting point.

vampirchik [111]

Answer:

680

Step-by-step explanation:

Ratio of red to white 4 : 7

Number of white = 280

White + red buttons = x

7x / 11 = 280

7x = 280 * 11

7x = 3080

x = 3080 / 7

x = 440

Number of red buttons 440 - 280 = 160

Number of red bottons ;

Blue + red buttons = x

3 : 2 ; blue : red

3 + 2 = 5 ;

2x / 5 = 160

2x = 160 * 5

2x = 800

x = 800 / 2

x = 400

Number of Blue buttons :

400 - 160 = 240

Total :

White + red + blue

280 + 160 + 240 = 680 buttons
