A (5,-3) does not belong
B (-2,4) does not belong
C (0,0) belongs
D (2,1) belongs
E (-5,2.5) does not belong
Step-by-step explanation:
To find the answer, you'll need to know
what is the number in half? If (x,y) is like
10,5 then that will belong.
Call Martha's age 5 years ago is x So Martha father's age five years ago is 7x
We have : 7x + 5 = 4(x + 5)
3x = 25+5=30 so x = 5 so Martha's present age is 10 and her's father's present age is 40
