Answer:
Step-by-step explanation:
8/v=6/v-3
8*(v-3)=6v
8v-8*3=6v
8v-24=6v
+24 +24
8v=6v+24
-6v -6v
2v=24
v=24/2
v=12 miles /hour
v2=12-3=9 miles /hour ( your friend)
The answer is 6/2 because there are 6 stars and 2 hearts. To simplify it, you can make it 3/1 by just dividing by 2.
Answer:
Quadrant 1
Step-by-step explanation:
how I understood this is first understanding how a graph works. Once you understand that you can count 13 horizontal on the "X" Axis, then go 18 up on the "Y" axis. you should get a point in the upper left area and that area is called Quadrant 1. Say if 13 was negative instead of going horizontal east you would go horizontal west. And the point should end up in Quadrant 2. Any more questions feel free to ask me below.
Answer: B (2,1)
You know what y is (x-1) so you substitute that for y in the other equation.
3x+ ((4)(x-1))=10
3x+4x-4=10
7x=14
x=2
Then put x=2 into y=x-1
y=2-1
y=1
