Given :
Distance between them, D = 14 miles .
Mr. Howard can run 3 miles in 30 minutes.
Ms. Egan can run 4 miles in 30 minutes.
To Find :
Time taken by them to meet.
Solution :
Mr Howard speed,
.
Mr Egan speed,
. [ Since they run in opposite direction ]
Their relative speed :

Time taken by them to meet :

Hence, this is the required solution.

Answer:
slope1 : 7, slope 2 = 3 solution: (2,5)
Step-by-step explanation:
I simplify some steps
pair 1: x1 0 2
y1 -9 5 ........ -9, y1 intercept
pair 2: x2 0 2
y2 -1 5 ........ -1, y2 interept
2 pairs meet at (2,5)
y=7x-9 ......A
y=3x-1 ......B
A-B 0=4x-8
4x=8
x=2
y=5
slope 1=( y2-y1) / (x2-x1) = (5- -9)/(2-0) = 14/2 =7
slope 2 = (5 - -1) / (2 - 0) = 6/2 = 3
Answer:
2a^4c-2ac^2-15
Step-by-step explanation:
Sorry, I not sure if this is right or not cause I don't know if the exponent for -4a^4c is that or -4a^4c-15, but I'm just going to go with -4a^4c. However aside from that you just combine like terms.
