Part a: explain why the x-coordinates of the points where the graphs of the equations y = 4−x and y = 8−x−1 intersect are the solutions of the equation 4−x = 8−x−1. (4 points)

part b: make tables to find the solution to 4−x = 8−x−1. take the integer values of x between −3 and 3. (4 points)

part c: how can you solve the equation 4−x = 8−x−1 graphically? (2 points)

Aflower has 26 chromosomes. to create a new flower, how many would a sperm cell have what is called?

What is x and y intercepts for y=x+7

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
