Solve 3* = 42. Round to the nearest hundredth.

Step-by-step explanation:

Given

Required

Find x

Take Log of both sides

Apply log rule

Make x the subject

--- approximated

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
