Yuto left his house at 10am to go for a bike ride. By the time yutos sister tiki left their house, yuto was already 5.25 miles along the path they both took. If yutos average speed was 0.25 miles per minute and rikos average speed was 0.35 miles per minute, over what time period in minutes starting from when riko left the house will riko be behind her brother

52.5 minutes

Step-by-step explanation:

VR=0.25  VY =0.35

ΔD=5.25

t=

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
