Your answer is C. because the paper is open like a kite or planes wings so it will float. With the crumpled paper it will fall instantly because its not open and has more mass

The equation of the graphed line in slope point form using the point (2,-1 ) is blank and it’s equation in slope intercept is bl
valkas [14]

Answer:

y=\frac{1}{4}x-\frac{3}{2} (Slope intercept form)

y+1=\frac{1}{4}(x_-2) (Slope point form)

Step-by-step explanation:

The slope of the line can be calculated as following:

m=\frac{-1-(-2)}{2-(-2)}=1/4

The the equation of the line in slope point form is:

y-y_1=m(x_-x_1)

Where (x_1,y_1) is a point of the line.

Then you must susbtitute the point given and the slope and you obtain:

y+1=\frac{1}{4}(x_-2)

The intercept form is:

y=mx+b

Where b is the y-intercept.

Solve for y from the equation of the line in slope point form obtained above, then:

y+1=\frac{x}{4}-\frac{2}{4}\\y=\frac{1}{4}x-\frac{2}{4}-1\\y=\frac{1}{4}x-\frac{3}{2}

Solve the equations in two different ways:6p=0.6(5p+15)
Damm [24]

Answer:

Step-by-step explanation:

1st way:

Solve directly

6p=0.6(5p+15)

Open bracket

6p = 3p + 9

Collecting like terms

6p - 3p = 9

3p = 9

Dividing by 3

p = 9/3

p = 3

2nd way:

6p=0.6(5p+15)

Convert the decimal to fraction

6p= 6/10(5p+15)

6p= 3/5(5p+15)

6p= 3/5(5p) +3/5(15)

6p = 3p + 9

Collecting like terms

6p - 3p = 9

3p = 9

Dividing by 3

p = 9/3

p = 3

A bag contains 6 blue marbles 10 red marbles and 9 green marbles. If 2 marbles are drawn at random without replacement what is t
umka2103 [35]

Answer:

P(1 and 2 are green) = 3/25

Step-by-step explanation:

We need to know the total number of marbles

6 Blue + 10 red + 9 green = 25 marbles

P ( 1st marble is green) = green/ total

                                       = 9/25

Since we don't put it back, there are  

6 Blue + 10 red + 8 green = 24 marbles

P ( 2st marble is green) = green/ total

                                       = 8/24  = 1/3

P(1 and 2 are green) = P(1st green) * P(2nd green)

                                  = 9/25 * 1/3

                                   = 3/25
