Answer: C. |-4 - 3|
<u>Step-by-step explanation:</u>
x = -4
y = 3
The distance between them is the difference. The mathematical operation for difference is subtraction.
Distance is a unit of measurement. Measurements cannot be negative so the absolute value sign is used to ensure the difference is positive.
The correct answer is 23/6. Hope this helps.

Answer:
20 miles (Answer B)
Step-by-step explanation:
The northbound biker travels (4 mph)(4 hr) = 16 mi, and
the eastbound biker travels (3 mph)(4 hr) = 12 mi.
They travel at right angles to one another. Thus, the Pythagorean Theorem applies here. The distance between the two bikers is d = √( [12 mi]^2 + [16 mi]^2 ), or √(144 + 256) mi, or √400 mi, which works out to 20 miles.
Answer B is correct.
