8x - 12 = 6x + 2
8x - 12 + 12 = 6x + 2 + 12
8x = 6x + 14
8x - 6x = 6x + 14 - 6x
2x = 14
2x/2 = 14/2
X = 7
Answer:
H(d) = 0.3d + 12
Step-by-step explanation:
It started at 12 inches.
Then it grew 0.3 inches per day.
Let d = number of days.
The growth is 0.3 d.
Add the growth to the original length, to get 0.3d + 12.
Answer: H(d) = 0.3d + 12
Yes, since the number 09 keeps going it is a repeating decimal.
Answer:
Part A: Yes, there should be a strong negative correlation between number of hours of internet browsing and score on math test.
