Answers:
x = 9
y = -3
==============================================================
How to get those answers:
Simply multiply the coordinates of the point (3,-1) by the scale factor 3.
The new x coordinate will be 3*3 = 9 and the new y coordinate will be -1*3 = -3.
The point (3, -1) moves to (9, -3) after applying the dilation.
The rule I used is where k is the scale factor, which is k = 3 in this case.
Note how k > 1 means the point moves further away from the origin. It also means we have an enlargement.
Answer:
Stacey is 16 miles far from the beginning of the trail.
Step-by-step explanation:
Given:
Stacey's total hike journey to NCT, Colorado = 18 miles
Distance covered by her to, a resting spot = 4 miles
We have to find:
How far from the beginning of the trail is Stacey hours after leaving the resting spot.
According to the question.
Distance remaining = miles
Time taken = hours Speed maintained =
mph
After leaving the resting spot she has covered a distance :
⇒
⇒
⇒ miles.
In hours she has covered
miles and also she has covered
miles before stopping here.
From the beginning she has covered :
⇒
