Answer:option A is the correct answer.

Step-by-step explanation:

Let x represent the number of days the customer paid for pet sitting.

She charges a flat service fee of $20, plus $20 per day. This means that the total amount that she charges for x hours would be

20 + 20x

If one of her customers spent less than $80, then the inequality that could be used to solve for x would be

$20 + $20x < $80

ahrayia [7]
Answer:

d = √13

Step-by-step explanation:

d = √((x2 - x1)² + (y2 - y1)²)

points: (-3, 8) & (-1, 5)

d = √((-1 - -3)²+(5 - 8)²)

d = √(2)²+(-3)²

d =√(4 + 9)

d = √13
