Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

There is a bag filled with 2 blue, 4 red and 3 green marbles.
Lyrx [107]

Answer:

.753

Step-by-step explanation:

Let Ps = probability both marbles are the same color.

Let Pd = probability both marbles are a different color.

Pd = 1 -Ps

Let Pb = probability both marbles are blue

Let Pr = probability both marbles are red.

Let Pg = probability both marbles are green

Pb= 2/9 * 1/9 = 2/81

Pr= 4/9 * 3/9 = 12/81

Pg=.3/9 * 2/9= 6/81

Ps = Pb + Pr +Pg= 20/81

Pd =1-Ps= 61/81 = .753

Is this correct?

Let the number of games, x, and the number of rides y, For 2x + 4y = 20, what is the slope of the graph? What is the slope? (Hin
hram777 [196]

Answer:

m= -1/2, (0,5), (10,0)

Step-by-step explanation:

Let us write it in slope intercept form, y=mx +b where m is the slope:

2x+4y=20

4y= -2x+20

y= -1/2x+5

Therefore, the slope is -1/2

The y intercept can be found when we substitue 0 as x.

y= -1/2*0 +5

y=0+5

y=5

(0,5)

The x intercept can be found when we substitute 0 as y.

0=-1/2x+5

-5 =-1/2x

x= 10

(10, 0)
