You circle the points on both sides and then you calculate them and get what you need...
Answer:
Step-by-step explanation:
Because midpoints were used to make similar triangles we can say
AC=2(DE)
5x+12=2(9x-20)
5x+12=18x-40
-13x+12=-40
-13x=-52
x=4
AC=5x+12
AC=5(4)+12
AC=20+12
AC=32

Its the 4th one have a great day
Answer:
Step-by-step explanation:
Hi there!
Because we're given the vertex of the parabola, we can determine its equation in vertex form:
where the vertex is
Plug in the vertex (0,0)
Now, we must solve for a. Plug in the given point (-2,3) and solve for a:
Therefore, the value of a is . Plug this back into :
I hope this helps!
