Midpoint formula is M=( (x1+x²)/2 , (y1+y²)/2 )
let A be there point (x1,y1), our (2,3)
plug into the formula to get
(-2,1)=( (2+x²)/2, (3+y2)/2 )
so -2=(2+x2)/2 and 1=(3+y2)/2
x2=-6 and y2=-1
answer is B
Answer:
The 3rd option
Step-by-step explanation:
The pattern is every 2 hours is $15 so 4 hours would be equal to $30
Since 4 hours would equal 30 and we need 12 hours multiplying both numbers by 3 would get you the answer
