When setting up a proportion to calculate scale drawings, how do you write the proportion? A)actual/actual B)actual/drawing C) drawing/drawing D)drawing/actual
The correct answer is option D: drawing/actual
Suppose there is a drawing that has a scale of 1:10. So, this means anything drawn with the size of "1" would have an actual size of "10" in the real world, so a measurement of 120mm on the drawing would be 1200mm on the actual/real image.
The slope of an absolute function at the point where it evaluates to zero is undefined. Here, when x=1, so |4x-4|=|4-4|=|0|, the slope is undefined. This is where the vertex of the "V" on the graph of the absolute value function.
