Answer:
-13
Step-by-step explanation:
Given that:
Average temperature for a period of 4 days = - 8
Average temperature for a 5 day period = - 9
Temperature on the 5th day:
(total temp for the 4 days + 5th day temperature) / 5 = - 9
Let 5th day temperature = x
Total temperature for the 4 days = 4 * - 8 = - 32
(-32 + x) / 5 = - 9
-32 + x = - 45
x = - 45 + 32
x = - 13
Assuming equation 2 is y = (2/3)x-6, then the answer is A) Parallel.
Solve 2x-3y = 6 for y and you'd get y = (2/3)x-2. The slope here is 2/3 as it is for equation 2 as well. The slopes are the same but y intercepts are different, so the lines are parallel.
