Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
