Answer:

y+32=3(x+8)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(1-(-32))/(3-(-8))

m=(1+32)/(3+8)

m=33/11

m=3

y-(-32)=3(x-(-8))

y+32=3(x+8)

Julian is using a biking app that compares his position to a simulated biker traveling Julian's target speed. When Julian is beh

Gwar [14]

Answer:

11 km/hr.

Step-by-step explanation:

Given information:

Simulated speed = 20/km/h

Time = 15 mins = 1/4 hr = 0.25 hr

Distance Covered as per simulated speed = $20\times \frac{1}{4}=5km$

Position of Julian according to the app = $-2\frac{1}{4}=-2.25$ .

Actual distance covered by the bike is

$Distance= 5 - 2.25 = 2.75km$

Formula for speed:

$\text{Average Speed}=\frac{Distance}{Time}$

$\text{Average Speed}=\frac{2.75}{0.25}$

$\text{Average Speed}=11$

Therefore, the average speed of Julian is 11 km/hr.

The combined age of three sisters is 74. The eldest sisters age is twelve less than the sum of both sisters age. The middle sist

Anni [7]

Answer:

Step-by-step explanation:

let their ages be x,y,z and x>y>z

x+y+z=74 ...(1)

x=(y+z)-12

or x-y-z=-12 ...(2)

y=z+5 ...(3)

add (1) and (2)

2x=62

x=62/2=31

from (1)

31+y+z=74

y+z=74-31=43

substitute from (3)

z+5+z=43

2z=43-5=38

z=38/2=19

y=19+5=24

so their ages are 31,24 and 19
