Answer:
39,144,000 km
Step-by-step explanation:
Hi there!
Distance traveled = time * speed
Given speed: 233000 km/h
Given time: 7 days
It's important to note that our speed is given in per hours and out time is given in days. So in order to find how far the comet has traveled we must convert days to hours.
There are 24 hours in 1 day.
So to convert days to hours simply multiply amount of days by 24
24 * 7 = 168
So the comet has traveled for 168 hours
Now we can find distance traveled
Once again distance traveled = time * speed
Given speed is 233000 km/h
Given time is 168 hours
Distance = 168 * 233000 = 39,144,000
So the comet has traveled for a total distance of 39,144,000 km
The coordinates of point J' is (0,-2) which represent the image of J
let J (x,y) ⇒⇒⇒⇒ J' (x',y') = (0 , -2 )
The graph was dilated according to the rule:
(x,y) ⇒⇒⇒ ( 0.5x , 0.5y)
so, for the x coordinate
∴ x' = 0.5 x ⇒⇒⇒ x = 2x' = 2*0 = 0
for the y coordinate
y' = 0.5 y ⇒⇒⇒ y = 2y' = 2 * (-2) = -4
∴ The coordinates of J is ( 0 , -4 )
∴ The correct answer is the first option
-8(x+13)=2(x-7)+4x
-8x-104=2x-14+4x
-8x-104=2x+4x-14
-8x-104=6x-14
Hope this can help.
