Afitness club requires $60 initiation fee and dues of $15 per month, write an expression for the cost of membership for n months.

f(x)=60+15n

Step-by-step explanation

f(x)=60+15n

because $60  once because you signed up and then 15 n because it will be $15 per month

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
