high school algebra

Question

1. Put in a+bi form 28+π-1200 2. Put in a+BI form Zsub1 - 32subZ 3. Define what is congruent to y=-0.7x^2 Vertex(-7,-6) opens down 4. Find absolute value /2x-3/ =3 for x (I used slash marks because i couldn't type value signs lol)

Answer 1

3 opens down vertex (-7,-6) congruent to y =-0.7x^2

in vertex form y = a(x-h)^2 + k where (h,k) = vertex = (-7,-6)

y= a(x+7)^2 -6 where you find a from y=-0.7x^2

y = -0.7(x+7)^2 -6

congruent means the two parabolas have exactly the same shape and size
