Question

Joanna is paid $14 per hour 

Alberto started bench pressing 50 pounds. he then adds 5lbs every week .

determine whether each situation is linear or nonlinear , and proportional or non proportional ?

Answer 1

If Joanna worked 0 hours, she earns $0 (0,0). This is a linear equation because if you graph it, it'll make a straight line.

Since Alberto STARTED at 50 bench presses, (0, 50)
this makes it a non proportional situation.

(0,0)= proportional.


Theyre both Linear

Answer 2

Answer: Both the situation are linear.

Explanation:

Since we have given that

Cost of per hour = $14

Let the number of hour be 'h'.

So, our equation becomes

`Amount=A(h)=14h`

Number of pounds he started bench pressing = 50 pounds

Number of lbs added every week = 5

Let the number of weeks be 'w'.

So, our equation becomes

`Amount=50+5* w\\\\A(w)=50+5w`

Hence, both the situation are linear.
