Answer:
Hope this helps :) look at the picture because I dont know how to type that
Step-by-step explanation:
(2x+5y=60)
- (2x-5y=-20)
-------------------
10y=80
y=8
2x+5(8)=60
2x+40=60
2x=20
x=10
Answer: linear
Step-by-step explanation:
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:
Step-by-step explanation:
-11x (5lx + 12)=(-11x)(51x)+(-11x)(12)
=-561x²-132x
