Multiplying a vector by a scalar means to multiply each coordinate of the vector by said scalar.
So, we must multiply both entries by 7:

Since 1 km is 100,000 cm there are 39,400 inches in a kilometer
The answer would be C because for every 1 inch, would be 8 miles, so we then multiply the inches by 8 to get to 8 inches, so we then multiply the miles by 8 and we get 64 miles.
D = 64 mi.
Answer:
Point A and point B have 11 units between
Step-by-step explanation:
If the distance between 0 and 10 is 10 also known as the absolute value, you just add one more unit because it starts at -1
So 10 + 1 = 11 and because we are using 10 is greater than 1 its positive so the answer is 11
