Answer:
The distance between the two points is
Step-by-step explanation:
The formula of the distance between two points (x1, y1) and (x2, y2) is
d =
∵ The points are (-1, 3) and (4, 2)
∴ x1 = -1 and x2 = 4
∴ y1 = 3 and y2 = 2
→ Substitute them in the formula of the distance above
∵ d =
∴ d =
∴ d =
∴ d =
∴ d =
∴ The distance between the two points is
Answer:
Jessica spent 10 months in Spain and 8 months in Colombia.
Step-by-step explanation:
Let x be the number of months Jessica lived in Spain, then she lived 18 - x months in Colombia.
She learned an average of 160 words per month when she lived in Spain, so she learned 160x words in Spain.
She learned an average of 200 words per month when she lived in Colombia, so she learned 200(18-x) words in Colombia.
In total, she learned a total of 3,200 new words, thus
Jessica spent 10 months in Spain and 8 months in Colombia.
