Step-by-step explanation:
p(x)=7x+20
p=7x/x + 20/x
answer p=7+20/x
I hope its helpful.
Y=4x-18 is the parallel equation
Y=mx+b Substitute
2=4(5)+b Multiply by 5
2=20+b Substract 20 in both sides
-18=b
If the ratio is 1:18, and we need to know how the other side for the ration 9:?, then we have to multiply 9x18.
9x18=162
so Laurel and Delmar are 162 km away

Answer:
0 People initially had the cold.
6 People will have it after 2 days.
Step-by-step explanation:
To find out how many people had it initially, plug 0 in for x (implying 0 days later.)
C= 1*3(0)
C= 1*0
C=0
Nobody had the cold initially.
To find out how many people had it after 2 days, plug 2 in for x. (implying 2 days later.)
C= 1*3(2)
C= 1*6
C=6
Therefore 6 people had the cold after 2 days.
I hope this helps!
