Hey those are linear functions, gotta find Y or X and draw on two axis X/Y. in first y = 4/9x + 1/9. in second y = X/2 - 2.
D(e-f)=g
e-f=g/d
(divide both sides by d)
-f=g/d -e
(subtract e from both sides)
f=-g/d +e
(divide by negative three)
... and yur done.
Answer:
1.2, 2, 2.8
Step-by-step explanation:
Hey there,
15x=6
=> 5x=2, 3x=1.2, 7x=2.8
Hope this helps :)
