The equation y=2x means: two times the input value equals the output value. If the
input value is -3, then what is the output
value?

7. if the value of x varies directly with the value of y, and x = 3 when y = 21. what is the valu y, and x = 3 when y = 21. what is the value of x when y = 105?

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
