Rotating counterclockwise 270 degrees would make the original Y value the new X value and the original x value would become the new Y value with the opposite sign.
So the new location would be (-9, 8)
Multiply bottom equation by -3 to add and eliminate y’s.
So...
5x-15y=10
+-9x+15y=18
You get -4x=28 so x=-7
Plug in to get y
5(-7)-15y=10
-35-15y=10
-15y=45
So y=-3
Check in other equation
3(-7)-5(-3)=
-21+15=-6
So x= -7 and y= -3

Step-by-step explanation:
Answer:
X=3
Step-by-step explanation:
11=3(X × ⅓) +8
11=3(X/3) +8
11-8=X
X=3
Answer:
-5 = <em>v</em>
Step-by-step explanation:
First you take the positive five and subtract it from -20 making it -25. Then you divide -25 by positve 5 and you get -5 making your answer -5 = <em>v</em>
