The six basic functions are: 1. function, latex: f\left(x\right)=xf ( x ) = x 2. function, latex: f\left(x\right)=x^2f ( x ) = x 2 3. function, latex: f\left(x\right)=x^3f ( x ) = x 3 4. function, latex: f\left(x\right)=\sqrt{x}f ( x ) = x 5. function, latex: f\left(x\right)=\sqrt[\: 3]{x}f ( x ) = x 3 6. function, latex: f\left(x\right)=|x|

What is the equation of a vertical line passing through the point (−5, −1)? y = −5 y = −1 x = −5 x = −1

What is the area of the trapezoid shown ?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
