For every 3 you go across you go up 1 so the gradient is rise/run = 1/3
Therefore gradient is 1/3
2x-14=-3x+6
You need to combine like terms and get all the x's on one side and the numbers on the other
2x+3x-14=6
5x=6+14
5x=20
now divide to get x alone
x=4
Hope that helps
Answer:
D
Step-by-step explanation:
Graphing calculator
When two linear equations have only one solution the two lines on a graph would intersect each other ( they would only touch in one spot).
Speed = distance/time
so to work out time you do distance/ speed
234/52= 4.5hours
