This is a long and tedious process but basically what you want to do is draw little rectangles to approximate the area. In this case what the problem wants you to do is
f(0)*2(length times width)+f(2)*2+2(4)*2+f(6)*2+f(8)*2+f(10)*2+f(12)*2+... +f(20)*2+f(22)*2=
(f(0)+f(2)+f(4)+f(6)+f(8)+f(10)+f(12)+f(14)+f(16)+f(18)+f(20)+f(22))*2=
approximately, I don't know how specific you're teacher wants them but Im putting down f(x) in integers for the sake of simplicity:
(9+10+11+12+15+18+21+26+27+26+17+13)*2=410
Answer is 3 sweets. so 12 left out of 20. Sally took 3 times more than Sammy.
<span>Describe the translation in words: (x, y) (x - 3, y + 7) =3 units to the left, 7 units up
Describe the translation as an ordered pair: 5 units to the right, 4 units down.
=(x, y)(x + 5, y – 4)
Describe the translation in words: (x, y) (x + 6, y – 2) =6 units to the right, 2 units down
Describe the translation as an ordered pair: 1 unit to the left, 8 units down
=(x, y) (x – 1, y – 8)
