Answer:
Amy makes more money
Step-by-step explanation:
Allison:
works 15hr
makes $5.25 per hr
(5.25)15 = 78.75
Allison makes 78.75 per week.
Amy:
works 15hr
makes 3.10 per hour
(3.10)15 = 46.50
plus 38 in tips
46.50 + 38 = 84.50
Hello!
The discriminant of quadratic functions is: b² - 4ac. Since the equation is in standard form, which is Ax² + Bx + C = 0 , we can substitute those values into our discriminant and simplify.
The value of the discriminant will tell us how many solutions there are to the given quadratic equation.
A positive discriminant will have two real solutions.
A discriminant of zero will have one real solution.
A negative discriminant will no real solutions.
1. Substitute, a = 16, b = 8, c = 1.
8² - 4(16)(1)
64 - 4(16)(1)
64 - 64(1)
64 - 64
0
Since the discriminant is zero, the answer is choice A, double root, because since it is raised to the power of 2, it must has two roots, but in this case, both of the roots the same x-values.
