Pick any number and add 1 to it. find the sum of the new number and the original number. add 9 to the sum. divide the new sum by 2 and subtract the original number from the quotient

For the quadratic function [tex]y=(x+4)^2-1[/tex] , do the following: a) rewrite the function in the standard form, b) rewrite the function in intercept form, c) find the vertex, d) find the y-intercept, e) find the x-intercepts.

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

If abcde is reflected over the x-axis and then translated 3 units left, what are the new coordinates d?
