The Decimal 2.6 converted into a fraction is
Let s = the speed of the slower train in km/hrs+10 = the speed of the faster train in km/hrLet t = time in hrs for the slower train to go 160 kmt-5 = time in hrs for faster train to go 160 km---------------Slower train:(1)
160=s.t
Faster train:(2) 160=(s+10) .(t-.5)From (1)(1) t=160/s
use the relations given in following screenshot and then use quadratic equation.
Answer:
Step-by-step explanation:
f(0)=2-3=-1 so the point (0,-1) must be on the graph
f(-5)=|-5+2|-3=3-3=0 so the point (-5,0) must be on the graph
Then, the correct answer is the second graph
Answer:
(5,14)
Step-by-step explanation:
4x-6=2x+4 because I chose any of the y values
change of subjects ⬇️
4x-2x =4+6
2x=10
2x÷2 and 10÷2
⬆️ making x stand alone
x= 5
put x into any of the equation
y=2(5)+4
y= 10+4
y=14
