Answer:
1/4,0.5, and 3/8 on edg
Step-by-step explanation:
Answer:
d=2
Step-by-step explanation:
3d + 6 = 12
first subtract 6 from both sides
3d=6
divide by 3 on both sides
d=2
y = -3(x<span> - 2)^2 + 1 </span>x<span>-coordinate of vertex: </span>x<span> = -b/(2a) = -12/-6 = 2 y-coordintae of vertex: y(2) = -12 + 24 - 11 = 1 </span>Vertex form: y = -3(x<span> - 2)^2 + 1 Check. Develop y to get back to standard form: y = -3(</span>x^2 - 4x + 4) + 1 = -3x<span>^2 + </span>12x<span> - </span>11<span>. </span>
I redrew the triangle (just turned it around it make it easier to understand).
