Answer:
The answer should be a positive 3 instead of a negative.
Step-by-step explanation:
The error is in the first step. The equation should've been set up like this...
-14+2y+4=4
-10y+2y=-4
2y=-4+10
2y=6
y=3
Answer:
NRS
Step-by-step explanation:
0.5(8-2x)=3-(x-1) Set up problem
4-1x =3-x-1 Distribute
4-1x =2-x Combine like terms
+x +x Add x to both sides to isolate x
4 =2 4 does not equal 2, so there are NRS.
Answer:
the last graph
Step-by-step explanation:
if you preform the vertical line test you will see that the last graph has no other x points that intersect
Answer:
The distance between the two train stations is 1728 km
Step-by-step explanation:
The speed of the bus = 54 km/h
The speed of the truck = 48 km/h
When the bus and truck meet again, the distance covered by the bus = 216 km more than he distance traveled by the truck
Let the distance between the two train stations = x
Let the location where they first meet be y from station A we have;
The location where they meet again = y - 216 km
Therefore, we have;
Location where they
The time for the truck and the bus to meet again = t
Therefore, 54 × t - 48 × t = 216 km
6·t = 216 km
t = 36 hours
Therefore, the time for the bus to travel x + 216 km = 36 hours
54 × 36 = 1944 = x + 216
x = 1944 - 216 = 1728 km
The distance between the two train stations = 1728 km.
