Answer:
285ab-159b
Step-by-step explanation:
distribute 13 and 23 into the parenthesis
78ab-117b+207ab+276b
combine like-terms
78ab+207ab-117b+276b
285ab-159b
Start by finding slope difference of y’s over difference of x’s
y-y1=m(x-x1)
Pick either point
y-6=-1(x+5)

Answer:
His usual speed is 105 km/hr.
Step-by-step explanation:
Let his usually speed be s km/hr and the distance between the towns be d km. So we have the equations:
s = d/6
s - 15 = d / (6 + 1)
from the first equation:
d = 6s and from the second:
d = 7(s - 15)
Eliminating d we get:
6s = 7(s - 15)
7s - 105 = 6s
s = 105.
