What is the rule for the reflection? a) r y=x (y, x) -> (-y,-x) b) r y=-x (x, y) -> (-y,-x) c) r y=x (x, y) -> (y, x) d) r y=-x (x, y) -> (y, x)

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
