7. Construct Arguments Cole orders 4 bags of salted potato chips, 3 bags of sour cream
and chive potato chips, I and 2 bags of
barbecue potato chips. Cole finds the cost
using the expression 4x + 3x + 2x, where x is
the cost of one bag of chips. Explain a more
efficient way to use an expression to work
out the cost. One bag of chips
cost $3. Five bags cost
$10

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
