1. 3*3 + 3*8 = 9+24=33
2. 4*4+.5*2*4+5*5= 16+4+25=45
3. 5*10+4*10= 90
4. 24+.5*4*4 = 32
It is not a function because there can't be two of the same number on the x-axis.
Let x be the number.
5 - 2x = 7
5 - 5 - 2x = 7 - 5
-2/-2x = 2/-2
x = -1
The number is -1.
Its either the first choice or last choice.
The answer is 64!!
Hope this helps!
