The function m(x)=30x represents the number of total minutes, m(x), that a student goes to extra help sessions, x. Erik wants to increase his grade so he goes to extra help sessions two times a week ("twice") for 10 weeks

900 minutes

Step-by-step explanation:

Given the function :

m(x) = 30x

m(x) ; function which represents number of total minutes ;

x = extra lesson session

If Eric goes for extra lesson session 2 times per week for. 10 weeks

Number of extra lesson sessions, x : (2 * 10) = 20 extra lesson sessions

Total Number of minutes :

m(x) = 30x

m(30) = 30(30)

= 900 minutes

your answer would be 12

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
