Wayne is solving a system of linear equations.

y = −34x + 5
x = −2

To solve this system, he graphed the line y = −34x + 5.

When Wayne graphs the line x = −2, at which point will he find the solution of this system of linear equations?

Sum is 17 and their difference is 3

(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.)
