Evaluate the expression when a=10 2a+3 =

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Find solution of the linear equation y = 2/3x + 1/3
