Answer:
1. D
2. D
3. H
4. B
5. B
Step-by-step explanation:
2x^2 -5x -3 = 0
D = 25 +24 = 49
x_1,2 = (5+/- sqrt49)/4 = (5+/-7)/4 = -2/4 = -1/2 and 12/4 = 3
x_1,2 = -1/2 and 3
hope this will help you
Answer:
7 P.M.
Step-by-step explanation:
Time at which the walk was begun = 4 p.m.
Finished after rotating the clock 90° i.e. = 3 hours

= 7:00 PM
Graph is accurate enuf so that you can determine immed that the vertex / minimum is at (3,-4) and that the y-intercept is at (0,5).
If by "solutions" you mean "roots," the roots are {1, 5} (where y=0).
Step-by-step explanation:
use the formula if things get to difficult
