Answer:
The equation of the line would be y = 5/4x - 4
Step-by-step explanation:
To find the equation of any line, start by finding the slope using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-4 - 1)/(0 - 4)
m = -5/-4
m = 5/4
Now that we have the slope, use that and either point to get the equation of the line
y - y1 = m(x - x1)
y + 4 = 5/4(x - 0)
y + 4 = 5/4x
y = 5/4x - 4

Answer:</h3>
<em>Your answer would be y=x+3/12</em>
<h3>
Step-by-step explanation:</h3>
Firstly, you'll switch sides of the equation.
<em>y=12x+3 ---> x=12y-3</em>
Next, add 3 to both sides.
<em>x=12y-3 ---> 12y-3+3=x+3</em>
Simplify it.
<em>12y-3+3=x+3 ---> 12y=x+3</em>
Then, divide both sides by 12.
<em>12y=x+3 ---> 12y/12 = x/12 + 3/12</em>
Simplify once more.
12y/12 = x/12 + 3/12 --- y= x+3/12
<u>y=x+3/12 would be your answer.</u>

Profit is what you earned minus what u bought.
hi,
You have to use a formula which is known as of binomial coefficient which is :
k among n is : C ( n /k) = n! / k! ( n-k)!
! = factorial
ex : 5 object among 8 is : C ( 8/5 ) = 8 ! / 5! * ( 8-5) !
As 8! = 8*7*6*5*4*3*2*1 = 40 320
As 5! = 5*4*3*2*1 = 120
as 3 ! = 3*2*1 = 6
then : 40 320 / 120 * 6
40 320 / 720 = 56
Conclusion : there is 56 way to select 5 object among 8 of them.
ps : you can also use Pascal Triangle to do such a thing.
