Answer and Step-by-step explanation:
Each package has 12 pencils
total number of pencils Sarah purchased: n = 12p
n = total number of pencils
p = number of packages
n depends on p, because the total number of pencils dependos on how many packages she will buy, so:
independent variable: p
dependent variable: n
╔═══╦══════════╦════╗
║ p ║ n = 12p ║ n ║
╠═══╬══════════╬════╣
║ 3 ║ n = 12*3 ║ 36 ║

║ 4 ║ n = 12*4 ║ 48 ║

║ 5 ║ n = 12*5 ║ 60 ║

║ 7 ║ n = 12*7 ║ 84 ║

Answer:
A,D,E, and F
Step-by-step explanation:
They all equal -1/4.
Steps:
1) Draw the circle and mark the center (A) and the given point (B)
2) Draw a line that passes through the center (A) and the given poiint (B).
3) Draw a perpendicular line to the segment AB.
The last line drawn is tangent to the circle at the given point.
Because it’s important to know the equation so that would be easy to know the quadratic formula and easy to solve the problem
