Answer:
y=3x-1 = x=1/3
Step-by-step explanation:
y=3x-1
to find the 0-intercept at x, underline y = 0
0=3x-1
move the variable to the left side and change its sign
-3x=-1
divide both sides of the equation by -3
x=1/3
Answer 6
Step-by-step explanation:
remove the para-these 2 x 3 x 5 / 2 power of 2 + 1
you get 30/ 5
30/5 =
6 therefore your answer is 6
As y decreases x increases so its an inverse variation.
y = k / x
when x = 2 y = 4
4 = k/2 so k = 8
the required equation is y = 8 / x
Check for the 2 last values:-
2 /3 = 8 /12 = 2/3 which checks out
