An exponent of zero automatically means the answer will beone, so the first tow will be one.I would need diagrams or additional information to solve theangles.As for the equations, put them through the quadraticformula:  x  =  −  b  ±                    b        2        −        4        a        c                    2        a                x  =  −  1  ±                    1        −        4        (        1        )        (        −        12        )            2          x  =  (  −  1  ±            49        2                −      1      ±      7        2  3 and -4Number Two is not a quadratic equation, it is a linearequation and is solved differently.To use substitution:y = 2x +1 y= x - 7Take the definition of the variable y (x - 7) and put it intothe other eqution.x - 7 = 2x + 1Simplify-8 = xx = -8Now plug that into the equation:y = -8 - 7y = -15The answer is (-8, -15)
