Please help me Brainliest for the first to answer or for whoever is correct... Please please please help me As a construction manager, you are asked to build a new road, which crosses the point (1,0). There is another road already built, which can be expressed as y = -1/2 X − 3. You are asked to build your road such that it crosses this road at a perpendicular angle. Find the correct value for a and b in the following equation of your road. y = + b

Write your answer as an equation in slope-intercept form.

Thank you!

The dash figure is a dilation if the original figure. find the scale factor. classify the dilation as an enlargement or a reduction

Let x have probability generating function gx (s) and let un generating function u(s) of the sequence uo, u1, satisfies p(x > n). show that the (1- s)u(s) = 1 - gx(s), whenever the series defining these generating functions converge.
