If y= -12 when x= 9 find y when x= -4

This is a fraction. So it's y over x. So -12 over 9 equals y over -4. After you put those in fractions, you cross multiply. So -12(-4) is 48, and 9y. Then you set them equal to each other, so 48=9y. You divide 9 on both sides and your answer should be y=5.3

Find the exact value of tan22.5 using the half angle formula.

mote1985 [20]

Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
