Solve by the method of your choicex + y = 22y = x2 – 4x + 4

Determine whether the given ordered pair is a solution of the system.(4, 5)4x + y = 212x + 4y = 28

Solve the linear inequality. Other than ∅, use interval notation to express the solution set and graph the solution set on a number line.-3(3x – 2) < -12x - 3

Solve the system by the addition method.-2x – 7y = 177x + 3y = 5

Use graphs to find the set.(-9, 0) ∪ [-3, 9]

Express the interval in set-builder notation and graph the interval on a number line.(-5, 9]

Solve by the method of your choice.x2 + y2 = 5 -7x + y2 = 11

Solve the equation by completing the square.x2 + 8x + 32 = 0

Newborn Josie is participating in a study that uses the high amplitude sucking paradigm. Josie hears a tone and starts sucking her pacifier quickly. As the same tone is presented again and again and again, her sucking rate decreases. Therefore, which of the following statements is TRUE?
