Answer:
Length of DE is 25.
Step-by-step explanation:
Right, so this is something called midsegment theorem. ΔDBE is similar (but not congruent) to ΔABC because of the angles they share. Since DE is described as a midsegment, this means BE=EC and BD=DA; so ΔDBE is half the size of ΔABC, meaning its side lengths are also half that of the larger triangle.

Answer:
1. -2
2. -10
3. -8
Step-by-step explanation:
1. you add 4 to -3 which is equal to one then you multiply 1 by -2 which is -2
2. 4-2=2 then 2(-5) is equal to -10
3. -7+3=-4 and 4-5 is equal to -1 then you multiply that by 2 which is equal to -2
If it has a single zero that means it has to be just touching the x-axis with its tip.
We know that if it has only one zero, the discriminant equals 0.
So,
Solving for k,
.
Hope this helps.
Answer:
The y-axis is the axis of symmetry.
Step-by-step explanation:
The vertical line through the vertex is the axis of symmetry. If that point lies on the y-axis, then the y-axis is the axis of symmetry.
It will be an even function, with no x-term. That is, it will be of the form ...
y = ax^2 +c
