Aman went on a camping and hiking trip over fall break after two full days 3/10 of his supplies were gone. how many days could he hike before he runs out of supplies?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

The graph below shows the height of a projectile t seconds after it is launched. if acceleration due to gravity is -16 ft/s2, which equation models the height of the projectile correctly?

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?
