Question

Peter played his favorite video game for 10 hours last week. Today Peter's parents restricted him to 5 hours each week for the next 8 weeks. Create the function, f(x), that models Peter's total video game time and explain what each number in the situation represents, using complete sentences.

Answer 1

he already got those 10 hours and now that everything is over
nobody can take them from him ; )

so whatever he will do,its always 10 hours on his account already.

Answer 2

always 10 additional hours*

Answer 3

let y, time he has played (in hours)

then

y = ........+10

Answer 4

@marinesrock what should be the independent variable here ?

Answer 5

the independent variable should be 5

Answer 6

if we use a formula, we use it to describe some "dimension" versus
another dimension...

Answer 7

the two dimensions here are:
- weeks
- hours played

Answer 8

so the independent variable is 8?

Answer 9

uhm, yea, well, you can also calculate the hours he spent playing
after 2 or 6 weeks with our formula :)

Answer 10

"that models Peter's total video game time"
they dont specifically ask
for the time in 8 wk

the formula must be flexible

Answer 11

ok so the equation would bey=5*8+10?

Answer 12

if you already solve for 8 weeks, that is correct

try to write it where x
is still flexible

Answer 13

x is number of weeks.

and that will be the solution to thisp roblem

Answer 14

so y=x*8+10

Answer 15

x is weeks(!)

he plays 5 hours/wk

Answer 16

ok so i need to put 5 in instead of 8?im confused on this stuff.math and me dont agree wit each other

Answer 17

yeah :)

Answer 18

you would put 5, fixed in there, becaue it's a coefficient that will get into effect for every week. how many weeks is still flexible at that point - but since x*5, that means every new week also increases playing time by 5hr

Answer 19

ok thank you for the help
