It's 14 because when you divide you get 13 with a remainder of 58 which is over half of 99 which means that you round up to 14
To find out if the points lie on the line y = 1/3x + 9, plug in the x value of the coordinate into the equation and see if the y value results in the same number
A. (0,9)
y = 1/3x + 9 Plug in 0 for "x"
y = 1/3(0) + 9
y = 9 This point is on the line
B. (-9,6)
y = 1/3x + 9 Plug in -9 for "x"
y = 1/3(-9) + 9
y = -9/3 + 9
y = -3 + 9
y = 6 This point is on the line
C. (3,10)
y = 1/3x + 9 Plug in 3 for "x"
y = 1/3(3) + 9
y = 3/3 + 9
y = 1 + 9
y = 10 This point is on the line
D. (12, -5)
y = 1/3x + 9 Plug in 12 for "x"
y = 1/3(12) + 9
y = 12/3 + 9
y = 4 + 9
y = 13 This point is not on the line
Your answer is A, B, and C
Answer:
C.
![12 \sqrt[3]{6c}](https://tex.z-dn.net/?f=12%20%5Csqrt%5B3%5D%7B6c%7D%20)
Step-by-step explanation:
![5 \sqrt[3]{6c} + 7 \sqrt[3]{6c} \\ = (5 + 7)( \sqrt[3]{6c}) \\ = 12 \sqrt[3]{6c}](https://tex.z-dn.net/?f=5%20%5Csqrt%5B3%5D%7B6c%7D%20%20%2B%207%20%5Csqrt%5B3%5D%7B6c%7D%20%5C%5C%20%3D%20%20%20%285%20%2B%207%29%28%20%5Csqrt%5B3%5D%7B6c%7D%29%20%5C%5C%20%20%3D%2012%20%5Csqrt%5B3%5D%7B6c%7D%20)
The average is the sum divided by the count.
144 / 4 = 36
