The x-coord. of the vertex is halfway between the given zeros. Here, it'd be halfway between x=3 and x=9, which comes out to x = 6 (answer).
4x + 10 = -26
-10 -10
4x = -36
Then -36 divided by 4
X= -9 -9 is the answer.
Answer:
t≥7
Step-by-step explanation:
11≤t+4
4 moves to the other side hence its sign changes
11-4≤t
7≤t
they change sides
t≥7
the sign was facing t so this does not change
