Answer:
(Slope intercept form)
(Slope point form)
Step-by-step explanation:
The slope of the line can be calculated as following:

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

Where (
,
) is a point of the line.
Then you must susbtitute the point given and the slope and you obtain:

The intercept form is:

Where b is the y-intercept.
Solve for y from the equation of the line in slope point form obtained above, then:

It’s A because rise/run
Rise is y and run is x because the run is going left it’s a negative
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
Answer:
22!
Step-by-step explanation:
Its just simple
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
