Which empty boxes? have you attached any pic?
Well the answer i think is going to be 18
Answer:
correct and incorect
Step-by-step explanation:
For 11, we can subtract x from both sides for the first equation to get y=8-x, making the slope -1 for both equations and therefore making it parallel.
For 13, we can solve for y in the first equation by subtracting 14 from both sides and therefore getting 2x-14=y. For the next one, we can subtract 4x from both sides to get 10-4x=2y. Dividing both sides by 2, we get 10-2x=y. Since for the equations to be parallel they must be the same and for perpendicular they must be -1/(slope), this fits neither.
Using those two explanations, I implore you to solve the other two on your own!
The temperature starts at 85 degrees.
t = 85
After 1 minute, it loses 3.5 degrees.
t = 85 - 3.5
After 2 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 2
After 3 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 3
etc.
After 12 minutes, it loses another 3.5 times 12 degrees.
t = 85 - 3.5 * 12
