4) The solution of 2 lines is where they intersect. In this case it is (4,4) for both lines A and B.
5) Two lines with infinite solutions mean that they are the exact same line, so you can change the original equation to y=mx+b form.
2x + 2y = 8 divide each side by 2 to get x + y = 4
Answer: B
Step-by-step explanation:
answer:
y=2x+6
solution:
Alright, since the line is PARALLEL, the slope will remain the same. let call the # we will add to that b (like the 5 in y=2x+5).
so the formula will be y=2x+b
to find be, we will plug in one of the ordered pairs
6=2(0)+b
6=0+b
b=6
So, our equation is y=2x+6
to check:
(-3,0)
0=2(-3)+6
0=-6+6
0=0
20%
Because Suppose x% of 20 is 4
That is
x100×20=4
or
x5=4
—> =4×5=20
So 20% of 20 is 4

The number of passengers that :
- Needs Transfer only = 13 passengers
- Are going to work only = 17 passengers
Let :
Passengers that needs transfer = T = 35
Passengers going to work, W = 39
Passengers who do not need transfers and aren't going to work = 12
Using a venn diagram :
Let the Passengers who do not need transfers and are going to work and needs transfer = x
Passengers who need transfer only = 35 - x
Passengers who are going to work only = 39 - x
To find x :
35 - x + 39 - x + x + 12 = 64
86 - x = 64
-x = 64 - 86
-x = - 22
x = 22
the number of passengers that need transfers but aren’t going to work will be = 35 - 22 = 13 passengers
the number of passengers that are going to work but do not need transfers will be : 39 - 22 = 17 passengers
