Answer:
Step-by-step explanation:
hello :
Part A : x+6y =6 means : 6y = - x+6
so : y = (-1/6)x+1 an equation for the line (D)
y = (1/3)x -2 is the line (D')
PartB : solution of the system : y = (-1/6)x+1 ....(1) color red
y = (1/3)x -2 ....(2) color bleu
is the intersection point : (6 ; 0)
PartC : Algebraically by (1) and (2) : (-1/6)x+1 = (1/3)x -2
(-1/6)x - (1/3)x = -2-1
(-x-2x)/6= -3
-3x = -18
so : x = 6 put this value in (1) or (2) : y = (-1/6)(6)+1 =0 the solution is : (6 ;0)
X=33/17
Here is how it works
By the way what you are working with is called improper factions, which is when the big number is placed over the smaller number.
Now 33/17 is also 1 16/17
35/17 is also 2 1/17
Now we can the proper fractions which are 1 16/17 and 2 1/17
1+2=3 and 16/17 + 1/17 equals 1
3+1=4

The answer is the third choice: y=-1/4x.
We find this by remembering that slop is rise over run. Since the rise is -1 and the run is for we can make it -1/4 as the slope, which is next to the x term. Since the y intercept is at the origin we do not have a b term from the formula y=Mx+b.
Let
x------> number of emails originally sent
we know that
so
Solve for x
Divide by both sides
therefore
