For this case we must indicate the solution set of the given inequalities:
Subtracting 14 from both sides of the inequality we have:
Dividing by 6 on both sides of the inequality:
We multiply by -1 on both sides, taking into account that the sense of inequality changes:
Thus, the solution is given by all values of x greater than 7.
On the other hand we have:
Subtracting 15 from both sides of the inequality we have:
Dividing between 9 on both sides of the inequality we have:
Thus, the solution is given by all values of x less than -3.
Finally, the solution set is:
(-∞, - 3) U (7,∞)
Answer:
(-∞, - 3) U (7,∞)

This is a linear equation with y-intercept $50 and slope $0.25/mile:
TC = $50 + ($0.25)x, where x is the number of miles driven.

Hello:
Use implicit differentiation : <span>y sin 12x = x cos 2y
y' sin12x+12ycos12x =cos2y -2x y'sin2y
when : x = </span>π/2 and y =π/4<span>
</span>y' sin12(π/2) +12(π/4)cos12(π/2) =cos2(π/4) -2(π/2) y'sin2(<span>π/4)
</span>y' sin(π/6) +(π/3)cos(π/6) =cos(π/2) - π y'sin(π/2)
y' (1/2) +(π/3)(√3/2) = - π
y' (1/2) =-(π/3)(√3/2) - π
y' = -π (1+√3)/3
an equation of the tangent line is : y- π/4 = ( -π (1+√3)/3)(x-<span>π/2)</span>
