Answer:
6 =t
Step-by-step explanation:
-9 (t – 2) = 4(t – 15)
Distribute
-9t +18 = 4t -60
Add 9t to each side
-9t +18+9t = 4t+9t -60
18 = 13t -60
Add 60 to each side
18+60 = 13t-60+60
78 = 13t
Divide each side by 13
78/13 = 13t/13
6 =t
Answer:
(x, y ) → (x - 4, y + 8 )
Step-by-step explanation:
4 units left in the x- direction means subtract 4 from the x- coordinate
8 units up in the y- direction means add 8 to the y- coordinate
Then the translation rule is
(x, y ) → (x - 4, y + 8 )
Answer:
Points B and C are opposite
Step-by-step explanation:
0 on the number line marks the center of the number line. To the right on the number line are positive integers and to the left from zero are negative integers.
Points B and C are opposite because they are each half way between 0 and 1 on the right and 0 and -1 on the left
