Solve each system of equations by graphing 4x-y=5 and. 2x+y=7

Identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)

Give me the equations of two lines that have the same slope but are not parallel.

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
