Given a value of x, find the value for -3x + 2
-3/2
-4. x=2
3x + 2 = 3x + 6 This is not possible.
3x + 2 = 0 3x = -2 x = -2/3
Given a value of x, find the value for -3x + 2
y = 2 sin 3x y' = 2(sin 3x)'(3x)' y' = 2(cos 3x)(3) y' = 6 cos 3x
y=2 sin(3x) dy/dx = 2 cos(3x) (3) dy/dx = 6 cos(3x)
x is 30 to work it out- 3x 30=90 90-2=88
-3/2
-4. x=2
3x + 2 = 3x + 6 This is not possible.
x = 87 so 3x + 2 = 261 + 2 ie 263
3x + 2 = 0 3x = -2 x = -2/3
3x - 7 = 2 3x = 9 x = 3
-2
3x+12 = 18 3x = 18-12 3x = 6 x = 2
