Bobby is trying to decide between two gym memberships. Gym A has a membership fee of $40 and then you pay $10 per class. Gym B has a membership fee of $30 and is $15 per class. How many classes will make the gyms the same price?

2 classes

Step-by-step explanation:

a: 10x+40

b: 15x+30

10x+40=15x+30

subtract 10x from each side

40=5x+30

now subtract 30

10=5x

5 times what equals ten

5*2=10

x=2

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

78.59 is the mean
