Answer: Vertex = (-1, 5) x-intercepts = No real solutions
Step-by-step explanation:
Vertex = -2/2= -1
-1^2 + 2(-1) +6
1 -2 +6
-1 +6
=5
Discrminats= 2^2 -4(1)(6)
4 -4(1)(6)
4-24
= -20 (It's a negative so there's no real solutions, meaning there's no xintercepts/R0XS)
440/55 = 8 hours
It will take him 8 hours
If the discrimination is equal to 0, there is one real solution
Answer:
t is 32t+3
Step-by-step explanation:
-16×t×2=32
32t+3
