Yes; 8
Yes; negative 8

12. Grass seeds grow rapidly. A grass seed has grown to a 12 millimeter tall blade of grass. Tomorrow it will be 23 millimeters tall, the next day it will be 34 millimeters tall, and on the next day it will be 45 millimeters tall. Write a rule to represent the height of the blade of grass as an arithmetic sequence. How tall will the blade of grass be in 15 days? (1 point)
A(n) = 16 + (n – 1)11; 194 millimeters
A(n) = 12 + (n – 1)11; 166 millimeters
A(n) = 13n; 195 millimeters
A(n) = 12n; 180 millimeters

13. A magician charges $50.00 for a visit and an additional $7.50 for each hour he performs. The function rule C = 7.50h + 50.00 describes the relationship between the number of hours h and the total cost of the visit C. If the magician will only visit a maximum of 8 hours, what is a reasonable graph of the function rule? (1 point)

14. What is the graph of the function rule?

y = |3x| – 1 (1 point)

Answer 1

Explanation:

11 = D. Yes ; -8

12 = A(n) = 12+ (n-1) 11 ;166 milliliters

13 = The first plot graphed is located nearest 50 to resemble the initial charge.

The last plot graphed should be located at the top of the graph vertical to 8 - the maximum hours he'll work.

Therefore, the answer is C.

14 = you have to select x-values and plug them into the equation. Once you plug those values into the equation, you will get a y-value. Your x-values and your y-values make up your coordinates for a single point
