Let x be equal to Jim's travel time
Let x + 2 be equal to Joan's travel time
distance = speed*travel time
6(x + 2) + 8x = 33
6x + 12 + 8x = 33
14x = 21
x = 21/14 = 3.5
3.5 hrs is the hours that Jim have been running until he met Joan.
Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
Answer:
The slope is 3/4 and a point on the line is (-5,2)
Step-by-step explanation:
This is given in point slope form
y - y1 = m(x-x1)
where m is the slope and (x1,y1) is a point on the line
y-2 = 3/4(x +5)
y-2 = 3/4(x - -5)
The slope is 3/4 and a point on the line is (-5,2)
