Use the procedure for solving variation problems to solve the exercise. y varies jointly as a and b and inversely as the square root of c. y=16 when a=4, b=4, and c=4. Find y when a=5, b=3, and c=16

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"
