what is the missing reason for the 2nd step in the proof below?
given: adi cd
prove: the slope of ad equals
the negative reciprocal
of the slope of cd.
.
statement
1. ad 1 cd
reason
given
given
2. the slope of ab is -1
the slope of cd is
3. aabd - adbc
the altitude to the hypotenuse forms
similar right triangles.
corresponding sides in similar
triangles are proportional.
5. the negative reciprocal
of cd's slope is
definition of negative reciprocal
6. the slope of ab equals the negative
reciprocal of the slope of cd.
substitution

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
