So let me help you!
Step-by-step explanation:
KF = 8 units
m∠DFE = 90°
-
We know that DK is 16 so you would just have to divide it by 2
-
Since EF is a bisector, split it right down the middle means it will be equal to 90 degrees.
Answer:
The parabolic equation does not intersect the linear equation.
Explanation:
Given equation's:
- y = x² − 5x + 9
- y = -2x
To solve , use substitution method by inserting 2nd equation into 1st
when substituted y = -2x
collect terms
simplify
Find discriminant:
As the discriminant is negative, it tell us that they both does not intersect each other.
