Y = kx
80 = 16k
k = 80/16 = 5
direct variation
The first 2 choices are corect
Answer:
24 miles
Step-by-step explanation:
Distance formula (d):
D = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
Home to library
(-4, 1) ; (-4, 9)
D1 = sqrt((-4 + 4)^2 + (9 - 1)^2)
D1 = 8
Library to park :
(-4, 9) ; (2, 1)
D1 = sqrt((2 + 4)^2 + (1 - 9)^2)
D3 = 10
Park to home :
(2, 1) ; (-4, 1)
D1 = sqrt((-4 - 2)^2 + (1 - 1)^2)
D2 = 6
Answer:
f(2/9) = 1
Step-by-step explanation:
f(x) = 3x + 1/3........find f(2/9)...so sub in 2/9 for x
f(2/9) = 3(2/9) + 1/3
f(2/9) = 6/9 + 1/3
f(2/9) = 2/3 + 1/3
f(2/9) = 3/3
f(2/9) = 1 <=====
