Question

Solve each equation by graphing both sides of the equation or inequality

Answer 1

Answer:

see below

Step-by-step explanation:

6.   $-3x^2+9=-3$

           $-3x^2 =-12$

               $x^2=4$

                $x=$ ±$2$

Solution: $x=2, x=-2$

Points of intersection:  (2, -3) and (-2, -3)

7.         $(x-2)^2-10\leq (x-6)^2-2$

     $x^2-4x+4-10\leq x^2-12x+36-2$

                   $-4x-6\leq -12x+34$

                            $8x\leq 40$

                              $x\leq 5$

Solution:  $x\leq 5$

Point of intersection is (5, -1)
