Step-by-step explanation:
The property of translations on a coordinate plane, is pretty easy to remember, if you go up, you add to the y, if you go down, subtract from the y
If you go left, subtract from the x, if you go right, add to the x.
Example: State the number of moves the x and y variable in each vertex had to go through and what direction, (-100, 27) to (100,0)
Answer:
The x had to go through 200 moves to the right to add 200 onto the x
The y had to go through 27 moves to the left to subtract 27 from y.
Hope this helps!
Answer:
-6 and 2
Step-by-step explanation:
look left and right on number line. count 4 places over going both ways
1/4 + 1/4 + 1/4 is the sum of unit fraction, there are 3 unit fractions
Answer:
Step-by-step explanation:
This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:
Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):
and cross multiply to solve:
638x = 4466 so
x = 7 hrs
