Well, let's see.secant = 1/cosinecosecant = 1/sine5/cosine + 3/sine = 0Multiply both sides of the equation by sine :5 sin/cos + 3 = 0But sin/cos = tangent .5 tan(x) + 3 = 05 tan(x) = -3tan(x) = -0.6'x' is the angle whose tangent is -0.6 .
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
C divided by5 then multiplied by 9 then add 32-30 divided by 5 x 9 +32=-22
There is no one solution to this problem. For example: y = x2 y = 5x y = x + 20 y = 2x / 5 + 23 These are just four of the infinite set functions that would give "y" a value of 25 when x = 5.
When you have decimals you times them buy 100 to get the percent so .5 equals 50% and .05 equals 5% and .005 equals .5%
