Which system is equivalent to 3x^2-4y^2=24 -6x^2-2y^2=11

Find the solution(s) to x^2-14+49=0

If abcde is reflected over the x-axis and then translated 3 units left, what are the new coordinates d?

(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.)
