A microscope shows you an image of an object that is 80 times the actual size. Therefore, the scale factor of the enlargement is 80. An insect has a body length of 7 millimeters. What is the body length of the insect under the microscope? I know it's 560, but not sure if m...

What is the image of A(3,-1) after a reflection, first across the line y=3, and then across the line x=-1? I believe (3,-1) but not real sure, doesn't the x stay the same?

The coordinates of the vertices of triangle CDE are C(1,4), D(3,6), and E(7,4). If the triangle is reflected over the line y=3, what are the coordinates of the image of D? I think (3,-6), but not real sure.

Thank you I see what I did wrong.

In the graph below, point D is reflected across the y-axis. What are the coordinates of it's image? The graph looks like D is below the x-axis to the right 3 places from y-axis and down 1 place from x-axis. So would my answer be (3,1)?

Hello Diana, Remember the three basic rules when dealing with logs: n * log(A) = log(A^n) log(A) + log(B) = log(A*B) log(A) - log(B) = log(A/B) Also note that log, and ln are both logarithms and interchangable, just with base 10 for log and base of nature exponent e for ln. Us...
