PLEASE HELP ME. WILL FAN AND MEDAL :D
Amanda exercised for 10 minutes every day in the first week, 20 minutes in the second week, 30 minutes in the third week, and 40 minutes in the fourth week. Billy exercised for 5 minutes every day in the first week, 10 minutes in the second week, 20 minutes in the third week, and 40 minutes in the fourth week. Which statement best describes the methods used by Amanda and Billy to increase the time they spent exercising?
Amanda's method is linear because the number of minutes increased by an equal number every week. Billy's method is linear because the number of minutes increased by an equal factor every week. Both Billy’s and Amanda's methods are exponential because the number of minutes increased by an equal factor every week. Both Billy’s and Amanda's methods are exponential because the number of minutes increased by an equal number every week.
Which answer choice is it?
Amanda is adding each time week 10 minutes
therefore it is a linear increase suppose f(x)=x+10 is the linear function that describes what is happening where the inputs are 10 minutes each week
the other one is linear as well written as y=ax , x number of minutes exercised a the factor of increase
