Lizzy's bank account earns 6% simple interest per year. She deposits $500, and after some time she earns $210 in interest. How much time, in years, must have passed in order for her to earn this much interest?

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

Δabc is dilated by a scale factor of 3 with the origin as the center of dilation to form δa′b′c′. the slope of is -1.2. the length of is p units, the length of is q units, and the length of is r units. the slope of is . the length of is units.

Lines a and b are perpendicular. if the slope of line a is 3, what is the slope of line b?
