"square defg is similar to square dꞌeꞌfꞌgꞌ. segment ef is 2 units and segment eꞌfꞌ is 6 units.

which scale factor was used to dilate square defg to form square dꞌeꞌfꞌgꞌ? (see attachment for the diagram and choices)"

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
