Part a at the toaster company, the weekly cost to run the factory is $1400 and the cost of producing each toaster is an additional $4 per toaster. choose a function rule representing the weekly cost in dollars, f(x), of producing x toasters. a f(x)=1400x+4 b f(x)=4x+1400 c f(x)=4x−1400 d f(x)=1400−4x

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?
