b=7
Answer:
The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
Step-by-step explanation:
The difference between continuous and discrete graphs and functions is that a discrete function allows the variables to be only certain points in the interval, usually only integers; meanwhile, a continuous function allows the variables to be any points in the interval. Here, both variables are discrete, that is, the number of people is {0, 1, 2, 3, ...}, and days are {Monday, Tuesday, Wednesday, ...}
Answer:
r = -1 or r = 13/3
Step-by-step explanation:
Solve for r over the real numbers:
abs(10 - 6 r) = 16
Split the equation into two possible cases:
10 - 6 r = 16 or 10 - 6 r = -16
Subtract 10 from both sides:
-6 r = 6 or 10 - 6 r = -16
Divide both sides by -6:
r = -1 or 10 - 6 r = -16
Subtract 10 from both sides:
r = -1 or -6 r = -26
Divide both sides by -6:
Answer: r = -1 or r = 13/3
