No, they forgot to switch variable labels after solving for the independent variable...
y=-8x+4
y-4=-8x
(y-4)/-8=x
Now that you have solved for the independent variable x, you switch the variable labels...
y=(x-4)/-8
f^-1(x)=(x-4)/-8 which should really be rewritten as:
f^-1(x)=(4-x)/8 :P
Answer:
Option B,contract job
Step-by-step explanation:
It is likely the number of hours in a work week is 40 hours .
With fifty weeks in year 2020 and 10 ten days of Bank Holidays,the gross annual income from the contract full time employment can be computed thus
gross annual income=$40*40*(53-2)=$81,600
The pay is $40 per hour
In a week 40 hours are worked
There are fifty three weeks in the year minus 10 days of holiday which represents 2 working weeks for a Monday to Friday job
The gross annual income for full time permanent role is $78,000
As a result,the full time contract job pays more
I think it is 3 good luck me saying this then u getting the wrong answer
Answer:
They will be picked up at 2 
yards above sea level
Step-by-step explanation:
Let us consider sea level as reference and positions above sea level as positive and below sea level as negative.
With respect to this reference,
the position of top most point is +17 
yards
and the position of lower most point is -13 yards
⇒ The position of midpoint is 
= +2
∴ <u>They will be picked up at 2 yards above sea level</u>
I think the correct answer from the choices listed above would be the second graph. The given inequality is given as x is greater than or equal to 4. So, the graph should include the value 4 then to the right of 4 in the number line. Hope this answers the question.
