Step-by-step explanation:
50 miles per hour as they have been driving at a constant speed of 50 miles per hour throughout the trip.300/6=50 and 250/5=50
Answer:
a) (11/7, 9/7)
b) There's no point of intersection
Step-by-step explanation:
a) x - 2y + 1 = 0
2x + 3y - 7 = 0
To find the point of intersection, we need to solve the system of equations and the result will be the point of intersection (x,y)

Now we substitute x in the second equation:

Now we substitute y in our first equation.
.
The point of intersection is (11/7, 9/7)
b) x -2y +11 =0
-x + 2y - 13 =0
We are going to follow the same procedure:


Since this system of equations doesn't have a solution, the system has no point of intersection.
Answer:
Step-by-step explanation:
Around 0
Answer:
Step-by-step explanation:
2x=5x+60.
0=3x+60 ( subtract 2x from both sides)
-60=3x(subtract 60 on both sides)
x=-20
Hope this helps plz mark brainliest if correct :D
