The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.
y=3x108/x
What are the wavelengths for X-rays with frequency 3 x 10^18
1 x 10^-10
3 x 10^-10 m
3 x 10^26m
9 x 10^26m

Next, chad created this graph with ordered pairs that show the possible ratios of the number of damage to defense cards in his deck. what error chad make?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

Part a: sam rented a boat at $225 for 2 days. if he rents the same boat for 5 days, he has to pay a total rent of $480. write an equation in the standard form to represent the total rent (y) that sam has to pay for renting the boat for x days. (4 points)
