Marissa wants to join a video game club. She will be charged a flat fee to join the club and will also pay for each game she purchases. The total amount she can expect to pay, in dollars, can be estimated using the function f ( x ) = 20 x + 90 , where x is the number of games purchased. What is the inverse of this function?

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

answer: can you give the

step-by-step explanation:

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
