Answer:
2√5
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
= √[1 - (-1)]² + [3 - (-1)]
= √(2)² + (4)²
= √(4) + (16)
= √20
= 2√5

Answer:
4
Step-by-step explanation:
The terms are separated by addition/subtraction symbols. There are 4 terms.
With parentheses around each term, you have ...
(9) + (14d) + (5w) + (7) . . . . 4 terms
_____
The two constant terms can be combined to give an expression with 3 terms:
14d +5w +16
y = 80x - 60
Answer is B. y = 80x - 60
Double check:
When x = 1, y = 80(1) - 20 = 80 -60 = 20
When x = 2, y = 80(2) - 20 = 160 -60 = 100
When x = 3, y = 80(3) - 20 = 240 -60 = 180
When x = 4, y = 80(4) - 20 = 320 -60 = 260
When x = 5, y = 80(5) - 20 = 400 -60 = 340
