If ΔXYZ is dilated by a scale factor of 3 about point Y, which of the following is true about a line A prime Y prime? line A prime Y prime is perpendicular to line AY.
line A prime Y prime is parallel to line AY.
line A prime Y prime passes through the center of dilation.
line A prime Y prime intersects with point X′.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

answer: the answer is 100 x 12,500, which is 1,250,000.

step-by-step explanation: emily solved for a part when she should have solved for the whole.  

875,000 should be the numerator of the equivalent ratio.  

70 x 12,500 is 875,000.
