Use the elimination method to solve the following system of equations. x+y=1 and x-y=-6 . the system has a single solution. the solution set is (x, y) (type an ordered pair, using integers or fractions.) b. there are infinitely many solutions. the solution set is (type an equation. type your answer in standard form.) c. the solution set is the empty set.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
