Answer:

B. (1, 2)

Step-by-step explanation:

In a function, each value used in as an x-coordinate can be used only once.

Values already used as x-coordinates: -3, 8, 0, -5

The answer cannot have -3, 8, 0, or 5 as an x-coordinate.

The only choice without one of those four values as an x-coordinate is (1, 2).

Answer: B. (1, 2)

s/4 = -1

We can multiply both sides by 4:

Please help ASAP! Only answer if you know the correct answer! Thanks :)

Answer:

29 Minutes

Step-by-step explanation:

The original speed is given in miles per hour (like a car), but the answer is asking for miles per minute, so we must convert the speed into miles per minute first. To do this, we set up this equation: \frac{10.1 miles\ }{1 hour}x\frac{1}{60minutes} which equals  \frac{0.168333333miles}{minute}. We can then divide the desired number of miles by the speed in miles per minute. Here is the eqaution for this \frac{4.9miles}{\frac{0.168333333miles}{1minute} }. The miles cancel and you are just left with 29.1 minutes after you divide 4.9 by 0.168333333. Hope this helps!
