Answer:
-6
Step-by-step explanation:
Substitutet -7 for y in -3(9+y): -3(9 - 7) = -3(2) = -6
C = child tickets
a= adult tickets
c + a = 157
6.20c + 9.30a = 1178.00
6.20c + 9.30a = 1178.00
-6.20c -6.20a = -973.40
3.10a = 204.60
a = 66 adult tickets
c + 66 = 157
-66. -66
c= 91 child tickets
Answer:
K'= (-2, 4)
Step-by-step explanation:
First we are going to rotate our point 270° counterclockwise.
The rule for a 270° counterclockwise rotation is 
, which means that we just need to interchange the coordinates of the point and change the sign of the x-coordinate:
Now, to shift the point 3 units down, we just need to subtract 3 units from the new y-coordinate of our resulting point form the previous procedure:
We can conclude that the coordinates of K' are (-2, 4)
Answer:
=21k-18
Step-by-step explanation:
Answer is 3, -9
6 units away means x+6 or x-6
-3+6=3 (you can draw a number line if it helps you)
Or -3-6=-9
Therefore answer is both 3 and -9
