WILL GIVE BRAINLIEST The number of visitors to a park is expected to follow the function v(x) = 5(x − 1), where x is the number of days since opening. On the first day, there will be a ceremony with 20 people in attendance. What is the function that shows total visitors, including the ceremony?

A. c(x) = 20 + 5(x − 1)
B. c(x) = 20 − 5(x − 1)
C. c(x) = 5(x − 1) − 20
D. c(x) = 100x − 100

If x + 10 = 70, what is x? a. 40 b. 50 c. 60 d. 70 e. 80

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.
