Answer:
Point-slope equation is
y-y1 = m(x-x1)
m is a slope, m=5/4
y1 = -5, x1 = 8
Point-slope equation is
y+5 = 5/4(x - 8).
Step-by-step explanation:
13 - (x+2) = 8
subtract 13 from both sides
-(x+2) = -5
divide by -1 to get rid of negative
(x+2) = 5
subtract 2 from both sides
x=3
Answer:
Both boats will be 54 miles apart after 3 hours.
Step-by-step explanation:
Given that from a point on a river, two boats are driven in opposite directions, one at 7 miles per hour and the other at 11 miles per hour, to determine how many hours they will be 54 miles apart, the following calculation must be performed :
54 / (11 + 7) = X
54/18 = X
3 = X
Therefore, both boats will be 54 miles apart after 3 hours.
It moves the line on the X axis to a different spot when moved
hope this helps <span />
I know you have 1 and 3 right but I'm sorry about not knowing the rest.
