Answer:
Just substitute "x" with "3".
Step-by-step explanation:
y = 2.4x + 3.1
y = 2.4(3) +3.1
y = 7.2 + 3.1
y= 10.3
Answer: 10.3 minutes
I got 36. I did 5-2=3, 3•180=540, 540/5=108, 180-108=72, and 72/2= 36
(-2,3). When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x).
